| Ms. Jaina Sabido fo P2RO, Inc. | 1. I just have one clarification because according to the specs, the requirement is 10 to 15 minutes backup time. I just need to know if-- can we specify the capacity of the batteries? Normally, for this kind of equipment, it only houses 7ah batteries. Can we identify how many units do we have inside the UPS |
1. Please refer to the Section VII of Bidding Document Technical Specification requirements. |
| Ms. Jaina Sabido fo P2RO, Inc. | 2. 200-220 volts, supposing these units will be installed in different locations, tama po ba? Normally, nilalagay na nominal input na ganyan, it's not actually a range. It only indicates na naga-apply tayo sa mga design ng kuryente sa Pilipinas. We have 220, 230, 200, 208. These are nominal voltages only. Iba po 'yung input voltage na sinasabi ni Sir na range. Let's say, for example, kinabit mo sya sa-outside ng Manila, medyo malikot po 'yung kuryente, doon papasok 'yung AVR range n'yo or 'yung input range n'yo. Say, 'yung kuryente nila doon pumapalo ng 190 vac, ibig sabihin kaya pa ng UPS mo. Tama naman po 'yung sina-suggest nila na medyo lakihan natin 'yong range, but I think for specifications sa mga biddings, we have to put in the minimum requirement. So, in cases na tumaaas sila, let's say, 290 'yong kaya nila-ang tawag doon ay upper limit or 'yong mataas na boltahe, mas maganda po. Pero hindi naman siguro kailangan na i-adjust natin 'yong range for everybody. Like, for example, 'yong sa ibang sites po, kadalasan po pagka kuryente, bumababa po kadalasan pagka outside ng mga cities-magaganda ang kuryente. So, on record, ang note ko lang po, for the nominal voltage, it's okay to put in 200 to 220. Minsan nga po 200 to 230, to adapt sa Philippine electrical supply. Medyo malikot po talaga ang kuryente natin at tayo ay naga-adapt sa 208, 220, 230 na mga boltahe. For the AVR range, sa inyo po 'yon, pwede n'yong lakihan. Ang ibig sabihin lang po kasi paglinakihan mo, pagkinabit mo 'yan sa isang site na 100 voltage ang supply, halimbawa po sa Bicol, 180, gumagana pa ang UPS mo. Pagka 170 na, magba-battery mode na ngayon ang UPS mo. Ano po ang disadvantage n'un? Sa unit, nagagamit 'yong baterya. So medyo-ang baterya po kasi is consumable. May number lang 'yan ng pagcha-charge. Kung nag-discharge na s'ya, nagamit mo na 'yung buhay ng baterya mo. Nonetheless, I don't think you have to adjust doon sa range. Pwede n'yo po sigurong i-consider pag if it's really a very---'yong specs n'yo, I think lahat naman po makaka-comply. Hindi s'ya masyadong stringent. |

| Mr. Lot Ramos of Faxcable | 1. 'Yong 15 minutes kasi, I think we need to have a standard na lang. Let's say, kung 10 minutes, 10 minutes. Kasi alam naman natin dito, lahat ng supplier ng UPS is the same as 7ah lang naman ang laman n'yan-ng battery ng UPS na 'yan. So kung magkakaroon tayo ng 10 to 15 minutes backup time, 'gaya ng sinabi n'yo, lagyan na lang natin s'ya ng loading. For example, 10 to 15 minutes backup time at 650 va load. Kasi po, pagnaglagay po kayo ng load na computer lang, iisipin namin na dapat mas more than s'ya or less than s'ya ng 10 to 15 minutes. For example po, 10 minutes at full load, parang ganoon po. Para lahat po kami apple to apple. Kasi pagnaglagay kami ng 10 to 15 minutes, anong load po 'yon? Isang computer, isang monitor. Tayo na lang po mag-specify kung anong klaseng load po. Kunyari, 10 minutes at 650 va load or 20 minutes at 50% load, para lahat po kami, apple to apple. Mahirap po kasi na iba-iba po 'yong specs e. |
1. See previous answer to BAC Queries dated March 21, 2018. Testing is done using optimal load. |
| 2. Ma'am, napansin ko kasi na 'you put a nominal input/output voltage. So, pag may hyphen, parang range s'ya. Might as well Ma'am, Sir, lagay na lang tayo ng 220, 230, 240 and then 'yong range natin, 'yong input natin, magbigay na lang tayo ng (+)(-), let's say, (+)(-)20. And then sa output range, ganoon din po, para identify natin kung ano po 'yung input, kung ano po 'yung output. Kasi po, may mga UPS po na pwede pong 200, pwedeng 220, pwedeng 230, pwedeng 240. If you say nominal voltage, we will give you a 230. So 'yung nasa specs po natin is a range of voltage. So we can offer 208. Payag ba kayo sa 208? So, I suggest Ma'am, hindi ko lang alam sa ibang bidder, na maglagay tayo ng nominal voltage ng unit. Kung 220, 230 or 240. Kung doable naman, fine na lang sa amin. At saka Sir, pwedeng pa-indicate 'yong range ng-kasi sabi ni Sir kanina, 'yong AVR range n'yo kanina is hindi s'ya swak sa nominal voltage. Normally Sir, 'yong 240 n'yo kaya pa ng hanggang 280 'yan e, the maximum. The battery surge of the UPS is hanggang 300 volts e. Pero ang UPS natin, siguro 220-280 is safe na. |
2. Please refer to the Section VII of Bidding Document Technical Specification requirements. | |
| 3. Pag meron kang 240 volts nominal, for example, nandoon ka sa isang city, sabi nga natin malikot 'yong boltahe, pero I give you a 240 voltage, kaya ko po sinasabi na dapat po ang AVR range nyo, ang UPS is kaya po hanggang 280. What if 'yong 240 n'yo, maximum mo 'yan, naging 250, battery ka kaagad n'un Sir. Lahat po ng UPS vendor dito can comply on the 280 volts kasi ang battery store ng UPS is 300 volts. We cannot just give you a UPS-actually kulang po 'yong specs ninyo. Kaya nga po kami nandito. Ma'am, 'yung sinasabi ko pong input nominal voltage, kung kayo po ang titingin, range po 'yung nandoon e. 'Di ba po? Range po 'yan. Kaya nga dapat po nakalagay po doon 200 or 220 or 230 or 240. Kasi po, pag ako bumasa n'yan, sabihin n'yo po sa akin kung hindi range ang pagkakaintindi n'yo d'yan. Kaya nga sabi ko, Sir, maglagay po tayo ng 230 at saka 'yung AVR range n'yo po, ilagay n'yo po. Kasi 240 po mababa para sa AVR na variable. Kung ako manufacturer ng UPS sa China at maglalagay ako ng 180 vac hanggang 240, mababang specs po 'yun. Kaya nga sabi ko sa inyo Sir, pinasa-suggest po namin na i-apple to apple natin 'yung specs para lahat po kami 'yon ang ibibigay. Kung sa nominal input/output voltage, lagay na lang po tayo ng 220, 230, 240. 'Yan po kasi ang standard sa Pilipinas. Hindi na po standard 'yong 200 e. Ang standard is 220, 240. Kaya lang po nagkakaroon tayo ng mataas na boltahe is because of the lugar, sa lugar natin, sa generator, sa mga-. So dapat may nominal input talaga tayo. We cannot, ako Ma'am I cannot accept that's hyphen e kasi kung technical guy ka, range po tingin ko d'yan. |

| Mr. Anthony Ebol of ASPEX, Inc. | 1. Yung pong 600 va, kung pwede pong huwang na nating specify kasi pag sinabi po natin na 10 to 15 minutes at 650 va, full load po iyon. Siguro po Sir, ang pinakamaganda po roon, 10 to 15 minutes backup time at PC load – one set of PC load. Ganoon na lang po. 'Yan naman po 'yong usually na ginagawa po natin sa mga previous na bidding po natin. Acceptance Testing, 'yon po 'yong mga ginamit natin, one set of computer lang po. Pag ini-specify po natin na 650 va, full load po 'yon Ma'am ng 650 va UPS po natin and wala pong makaka-comply kung 7ah battery lang po ang gagamitin natin doon sa 10 to 15 minutes backup time. |
1. Please refer to the Section VII of Bidding Document Technical Specification requirements. |
| 2. Ma'am meron po ako ditong picture po that may help sa TWG po natin kung ito po ba ang type of universal socket is acceptable po. (Shows to the TWG a photograph on hind mobile phone.) 'Yan po 'yung socket na pwede po 'yung bilog, pwede 'yong flat. |

| Ms. Christina Co of LSI Leading | 1. Yong 650 va po, I think everybody failed to mention 'yong watts. Kasi po may watts po kasi na corresponding sa 650 va. There is a 300 watts, 325 watts. Normally, pagka 'yong standard, they base on the watts and then at a full load. So, let's say 650 va, nag-offer 'yong isa ng 650 va na 300 watts, normally ang full load n'ya, 5 minutes full load backup time. Regardless kung ano basta pagnag full load ka at 300 or 325, depende kung ano ang inoffer ng bidder, basta 650 va. Normally, sa 650 va, pagsinaksakan 'yan ng –nag agree ako doon sa sinabi kanina ni Sir na pagkasinaksakan 'yan ng monitor na may cpu, nagla-last talaga 'yon sa more or less 10 to 15 minutes 'yong ano n'ya but then again, 'yung 'yong ginagamit mo s'ya. Pero pag hindi mo s'ya ginagamit, mas mababa pa 'yong uptime n'ya na ilalabas. Doon naman sa sinabi ni Sir, to get exactly 'yong-let's say, we will load a 300 watts, to get exactly 'yong backup time na lalabas na gusto n'yo, if you want 15 minutes or 10 minutes, hindi na s'ya magfo-fall talaga doon sa 650 va na isa ang baterya. Pag mag-load ka ng 300 watts or 325 watts, which is the standard watts ng 650 va, hindi po sya papasok sa 10 to 15 minutes na full load kaya 'yun 'yong ine-explain nila na ano ba talaga 'yong gagamit na load. Pero to simplify it, I would suggest na kung 650 va, specify n'yo na lang kung 300 watts or 325 watts at PC load or you want it at full load which is 5 minutes backup time or seven minutes backup time. Mate-test nyo naman po 'yan sa isang baterya. So everybody will offer 'yong 650 va with one battery. |
1. Proposed ABC was based from the latest Market Survey using the Technical Specification requirements. |
| 2. Suggestion ko Ma'am, ilagay na lang kung ano 'yong prefer n'yo na watts doon sa 650 va, pero iba-iba nga ho 'yan, may 300 or 325 pero doon lang naman sya, dalawa lang naman- Pagmagbe-base doon sa full load na 300 watts, hindi ho papasok 'yung 10 to 15 minutes kasi at full load, 300 or sometimes, dalawang PC ang nalo-load sa 300 to 325 watts. So kung iisa lang po 'yan, papasok naman 'yong 10 to 15 minutes but we need to specify the wattage nun 650 va. |
2. Please refer to the Section VII of Bidding Document Technical Specification requirements. | |
| 3. Ma'am, second question doon sa universal socket. Ano po-kasi dalawa po ngayon ang klase ng universal socket, 'yong una kasi before, universal na bilog lang s'ya-bilog at flat. Ngayon kasi, may makapal na flat at saka bilog. So mas malaki ho 'yong universal socket ngayon. Are you referring-baka pwede i-bid bulletin na lang kung anong universal socket. And then doon sa three socket na 'yan, includied na po ba d'yan 'yon surge sa three universal socket na 'yan Sir? So bale, tatlong saksakan lang talaga s'ya sa likod? |
