I have 3 identical 28v battery charges that have all been blown because they were wired incorrectly to 2 x 12v sealed lead acid batteries (in a 24v series connection). I suspect a MOSFET is blown, but I'm battling to find the parts.
The specific MOSFETS have the following printed on them:
N6D
KCH30A10
DO1145
W20NM60
The chargers have the following data spec:
Material number: FL-C40417
Input Scope: AC 220V
Input Power: <\ 80 Watts
Output Voltage rated: DC 24V
Equal charging voltage:29.8+-0.2V
Floating Charge Voltage: 27.8+-27.8+=0.2V
Max Output Current: 6.5A
Overall unit productiveness: 80%-90%
