During normal operation the output voltage will automatically match input
voltage. On loss of input voltage the internal standby battery will supply the load,
only BATT and the voltage indication will be illuminated at this time.
The battery will continue to supply the load until either the input is restored or its
Deep Discharge Protection threshold is reached, whereupon the UPS will
automatically shut down.
The UPS will fully recharge from cut-off in approximately 12 – 16 hours
Should the output be overloaded or become short circuit the UPS will
automatically disconnect the output and illuminate the PROTECT LED.
Remove short/overload and cycle the input to reset the UPS.
Note: The UPS will automatically switch off after 30s in standby mode if the load is
<50mA
