Its frozen and cannot load


It is power supply regulator problem.
In the regulator circuit, DC 12volt from adapter is separated into +8V, -8V, +5VA, +5VD'
Some causes when the unit hang / frozen is one of the existing supply voltage is drop. In general, +5V.
Also check the adapter voltage, if still normal and the current is sufficient. Adapter must have DC12volt and current of at least 3 amperes.
It may happen, when the adapter is measured without load, it's read normal,12v. But when loaded to turn on the keyboard, many voltage decreases (lets say,between 8-10v). This indicates that the adapter is not good.

Sudden discharge of batteries


The icon may indicate the batteries are fully charged and your measurements would indicate this but I suspect the batteries are no good..

We usd powercom ups 6000va and 3000va [ mce brand] the problem is battery failure please help as Best regards john whyte


Does the UPS work when A/C voltage is present, if yes remove the battery, confirm that the battery can retain charges by using external load with a multimeter to get a steady 12V for about 30 sec before the voltage starts to drop. If the battery does not retain charges, replace the battery. However, Not that when you open the UPS your are exposed to life Voltages and run a great risk of electric shocks. Experienced technicians are expected to work on this kind of equipment.

How should i connect four batteries in two batteries microtek ups


You should connect them parallel too to the other two parallel batteries.
While connecting, make sure you are connecting all blocks in parallel wirth the correct polarities. Also once all the batteries are connected measure the battery voltage at the UPS terminal and make sure it is around 12V

Ups after 1 hr automatic disconnected and on only battery mode.


I have to believe that the problem is in the smart chip, with the software that monitors the power. There is a very good chance that you have a slightly higher input voltage then normal. You may have to contact Powercom.....

I don't think you are in the USA...I sell Powercom and I don't recognize the part number. I think this is simular to the IMD 625 Va UPS sold here in the USA. The imperial model had a defect on the smart chip two years ago here in the USA, and I figured it out for the MFG, so maybe that same chip is acting up for you. Besides, the 600VA size should be too small for you know. You should upgrade to a 1000VA. It will handle the load much better.

Trying to power a amp with 16 volts. possible?


Golf carts do not have a charging system. If you are going to use battery power only, why not just add (1) 12V car battery instead of (2) 8V??

MA Audio runs (ran) their bench tests @ 17V. All the power ratings advertized are at 17V.

The power supply for the hk4000D is unregulated. So the more voltage = more power.. 8V-16VDC.

  • RMS Power @ 14.4V
    • 1800W x 1 @ 4 Ohm
    • 3600W x 1 @ 2 Ohm
  • RMS Power @ 17.0V
    • 2000W @ 4 Ohm
    • 4000W @ 2 Ohm
    More input voltage means the amplifier will have to work less hard to make power.
    Don't expect the amplifier to work for very long however. the current drain on a class D amplifier is huge. There are no on-board fuses protecting the power supplies, so be sure to have at lease a 150A power line fuse.
    With 150A current draw - even with the amplifier at 1/2 gain - expect to get 10.6 minutes of listening time from your 16 volts before recharging - also note, the amplifier MUST see 8V to turn on, there is a built-in voltage sensor that will shut down the amplifier if voltage is too low.

    Wanting to install a mp6212 cd player in my tool box at work


    for proper operation, you will need 12V.
    Some vehicles wont start unless there aer 8V.
    Minimally 8VDC, but 12V recommended for proper internal amplifier operation. Purchase a used PC Power supply, and wire directly to the hard drive power pug. Inverters are also available.
    BTW Amps are a measure of AC Current, not DC. DC is measured in Volts.
    An Electrical appliance rated to work on AC will not work with DC, and vice versa.
    You will need an invertor of some type to change the signal and wavelength.
