2CV(constant voltage)16.8Vdc, 5A
3 Float stage5%CC
4Power efficiency≥ 90%=230Vac, Vin=230Vac, rated load

4.3: Protection characteristics
Technical specification
Remark
1Over voltage protectionYes
2Software over voltage protection.
The charger software limits the maximum output voltage to a level suitable for the connected battery system.
3Thermal protection Yes
4Current limiting protection YesAt CC mode
5Short circuit protection
Short circuit protection should be automatically recovery after remove the condition.
6Reverse polarity protection, .
When output wires are reversely connected to the battery the charger will not operate and will work normally when DC wires are correctly connected.
