Product Descriptions:

User(s) may choose to/not to use the DC UPS supply via the switch when utility power is available;

During mobile use, recommend to adopt soft-startup to better protect load from current impact;

Wide input voltage65-265V;

Environment-friendly batteries (Ni-MH) are adopted;

Free from minimum load limitation;

Audio and visual alarm (optional);

Battery low voltage protection;

Battery high voltage protection;

Overload protection;

Output short circuit protection;

Lightning protection;

Surge protection;

Fault-triggered auto shutdown;

Two lines of AC socket output; simultaneously switch to the utility power if it is available.


Use Instructions:

1. For the first use, the DC UPS should be fully recharged; switch off and continuous charging for 10 hours with connecting AC power supply.
