floating charge)

Working temperature: -5℃~ +40℃

Storage temperature: -40℃~ +70℃

Protection feature:

I.Output over voltage protection: charger will be in standby protection state if output voltage is over setting max voltage.

II. Output current protection: charger will be in standby state if output current is over setting max current.

III.Output short circuit protection: when positive and negative of output port of charger short circuit,  charger will be in protection state, it will resume after troubleshooting

VI. Battery reverse protection: fuse wire fusing if positive and negative  of output port of charger connect with positive and negative of battery by reverse .  It will resume after new fuse connect by correct way.
