Centaur Battery Charger doesn't produce output amperes

Centaur Battery Charger 24/60 doesn’t produce amp output, still 120 VAC are present at input, and 25 VDC present at output.

The questions are:
What would be the cause and solution?
Why voltage is not raising?
Why the charger is not feeding amperage to the batteries?

I have not connected the frame / chassis with an external wire to the input AC PE terminal… nor to the negative output DC terminal.

Is it ok to assume those connections are already made in factory?

Update: :grinning:
Will somebody please help ?

Output voltage is too low.

Correct, output voltage should be 29V-Absorption, 37V- Float… so the reading is showing the connected batteries voltage.

The questions are: What would be the cause and solution?
Why voltage is not raising?
Why the charger is not feeding amperage to the batteries?

Check it is switched on. If it is the unit is faulty. Replace the unit.

I cannot find a “switch”, to “switch it on”, the charger is connected to 120 VAC, and I measured the voltage at the input terminals as 124 VAC.

Pulled this from the manual…

Charger does not function

  1. The mains is not ok Measure mains (you checked so ok)
  2. Input or output fuses are defective (seems like the most likely problem)
    Return product to your dealer

Hello,

We had similar issue. In our case the “ON” led on the pcb didn’t light up. Reason : the NTC (situated behind the big plate) was broken. ( totally burned).

Replacing that NTC made the charger function again.
