  sir marami salamat sa info. ipapakalas ko n lang muna ung sirang led driver sa electrician, hirap kc tangalin ung chandelier mabigat. tignan k maige ung specs ng lumang led driver, about dun sa 1st pic hindi kailan lagyan cya ng isulation? ganyan lang cya pag kinabit? hindi nakaka kuryente kung nahawakan mo ung other case nya? thanks

  sir marami salamat sa info. ipapakalas ko n lang muna ung sirang led driver sa electrician, hirap kc tangalin ung chandelier mabigat.

  
  pinakamabigat na LED Chandelier na benta namin before is 30kg (hinde pa yan custom ha... kapag customized nasa 50-62kg kasi merged yung 2 same fixtures)
  
  kung yung 1st pic I mentioned apparently pwede rin naman ikabit ng L at N para umilaw.... pero you should make a ground wiring para safer... those boxes has a ground output, pero by my experience kahit bakal yang katawan pwede ka mapa electric shock niyan... then again ginagamit din namin sa LED Strip Lights (apparently most LED chandeliers use LED striplights of SMD5050 and SMD3528 ones
  
  okay.. eto yung types ng LED driver based from my experience on LED chandeliers
  - Naked types: Basically hubad pero covered with shrink wrap wire covers, yun ang hardest kasi walang specs posted worst nito kahit sa manual ng LED chandeliers wala rin sinabi ilang voltage and wattage
  
  - Encased ones: usually meron yan at common sa LED fixtures and LED Panel lights kung parang Bakal na block yung driver nila which is supposed Waterproof to a certain degree, yung pinost ko dati sa 2nd which is low end ones
  
  - Heavy duty types: usually nasa 12v and 24v versions, comes with different wattages to suit your LED applications... usually striplight ang gumagamit niyan pero meron naman sa Chandelier

  Good day. Ask ko lang po pwede po ba gamitin ang laptop charger as ac adaptor sa led tv na parehong 19v 2.1a. Salamat po.

  Follow the polarity ng connector of the AC adaptor/laptop charger to the LED TV
  
  
  
  
  Just make sure compatible or tama polarity...

  Hi All!
  
  Question naman, will this USB DC 5V to 12V Connector Step Up Module safely work with my Alcatel Travel Charger?
  
  USB DC 5V to 12V Specifications:
  Input Voltage: DC 5V
  Output Voltage: DC 12V
  Max Input Current: 2A
  Max Ouput Current: 750 mA

  No.
  
  The 5 to 12 v converter can draw up to 2A of 5v, while your travel charger can only supply 1A of 5v.

• ronnel0918 on 12 Mar 17 @ 11:53 AM #

  I assume this Anker 2-Port 24W USB Wall Charger will work?
  
  Product Specs:
  * Input : AC 100-240V~0.7A 50-60Hz
  * DC Output : 5V / 4.8A

  Good Day mga sir. Ask ko lang kung sino me alam sa inyo na gumagawa ng pedal effects? nasira na kasi yung effects ko, gusto ko sana ipagawa.
  
  TIA

• aezmuth on 23 Mar 17 @ 08:13 AM #

  Tanong lng mga sir. I have a 2.1 speaker which has a 3.5mm jack. Planning to use it on a DVD. Gagana po kaya pag ginamitan ko ng ganito? May nkagawa na kaya sa inyo?
  
  
  
  
  dto ko nlng tinanong wla kasi ako makitang active na speaker thread. Thanks.
  
  Creative sbs a120 pala ung speaker

  supposedly yung DVD mo merong RCA connector for audio out (at least yung [OUT] merong Yellow-Red-White na circular plug)
  
  kung walang Speaker/Audio out ang DVD player mo pwede sa row ng saan mong sinaksak yung Video RCA to LCD/LED TV yung Audio side
  
  ang resulta niyan dapat lalabas sa RCA Audio Connector to 3.5mm jack to your speaker... ang worst case niyan ay sound nito ay medyo mahina or konting hissing

• MaHkee on 24 Mar 17 @ 07:10 AM #

  Hi po,
  
  Nakabili ako ng Panther AVR 500VA, is't natural na mas madalas ang flickering ng monitor ko w/ matching sound ng parang voltage drop sa avr ko? Kasi nung ups and direct wall pa ang power source ko hindi naman ganito kadalas, nang yayari lang dati tuwing nag sstart ang motor ng ref. But now, walang minuto na di sya nag fflicker.
  
  Thanks in advance sa may alam if it's natural or something is wrong. Thanks!

• vanguardwars on 24 Mar 17 @ 02:23 PM #

  5v 2A power adaptor ng TV Box
  at
  5v 2A USB chargers ng phone ?
  

  
  
  Yup, same lang yan, kelangan mo lang alamin is yung polarity ng both chargers, check mo sa markings kung pareho. Kung makakahanap ka pa ng more than 2A na charger, mas maganda.

• vanguardwars on 24 Mar 17 @ 02:24 PM #

  @MaHkee,
  
  Mukhang underpowered ang AVR mo. Di kinakaya ng AVR mo yung load. Saan nakasaksak ang AVR at ano ang nakasaksak sa output nya?
  
  Meron ako dating Stavol AVR (Servo), nagloloko rin, as in, maya't maya ang trip to adjust the fluctuating voltage, pero nag flicker pa rin ang TV and PC ko.
  
  Then one time napansin ko yung breaker switch nung outlet ay mainit, meaning, the AVR is drawing too much current trying to compensate the voltage. So ang culprit ko is yung Breaker too low ang Ampere Rating. Pinalitan ko ng mas mataas na Ampere Rating, ayun umokay na si AVR ko. Maririnig mo pa ring umaandar yung Servo pero hindi na nagflicker yung mga naka saksak.

  Yung nagiisang 5v3a natagpuan ko, shipped from china pa,
  kaya chaga nlng po ako sa 2a.

  Sir,
  
  Magpapatulong lang po. Meron kasi kami ganitong motor bike na may 6v rechargeable battery.
  
  
  
  Nawawala na po kasi yung charger. Yung output ng original charger ay 7.2v 350ma. San po kaya pwede makabili ng replacement charger? Ok lang po ba kung gamitin muna temporarily yung charger na 12v 2000ma?
  
  Natry ko na po yung 12v na charger. Yun lang kasi nakita ko sa bahay na kasize nung original charger. Nagchacharge naman, pero di ko sure kung safe gamitin.

  sir you have to follow the voltage and the polarity ng connector ng charger..... for safety reasons
  
  wrong polarity or over-voltage might result in nasty situations (mahairap kung aapoy bigla)
