Feature of PSW7 Series Inverter&Charger
♦ High overload ability of our PSW7 charger is up to 300% rated power(20 sec)

♦ PSW7 pure sine wave inverter adopts low quiescent current, and power saver mode to reduce power consumption to 10W(3s sensing cycle)/3W(30s sensing cycle) *. It can extract max.
power from various batteries with different protections, and low voltage trip can be selected (9.5V/10V or 10V/10.5V).

♦ Uses PFC(power factor correction) for charger, which has less power consumption than conventional units.

♦ It has 15s delay before transfer when AC resumes, and overload protection when our PSW7 pure sine wave inverter equips with generator.
♦ 10ms typical transfer time between battery and AC, which guarantees power continuity of PSW7 charger. Uses selectable input AC voltage (184-253V or 154-253V) for different kinds of loads.
♦ Our PSW7 charger allows start up and through power with depleted batteries. Its powerful charge rate up to 90Amp.
♦ It can offer 3-step intelligent battery charging, and equipped with 8 preset battery type selector for totally flat batteries.

♦ LCD status display, battery/AC priority switch, USB communication port are available for our PSW7 pure sine wave inverter, it also has 17 alarms/warnings for easier operation and trouble-shooting,and ability to switch the unit on/off. In addition, select/deselect power saver mode can be used too.

Low Battery Trip Volt:
The Low Battery Trip Volt is set at 10.0VDC by default. It can be customized to 10.5VDC.
AC Input Range:
There are different acceptable AC input ranges for different kinds of loads.
It can be customized from 184-253VAC to 154-253VAC.
Load Sensing Cycle:
The inverter is factory defaulted to detect load for 250ms in every 30 seconds. This cycle can be customized
to 3 seconds thru the SW3 on DIP switch.
AC/Battery Priority:
Our inverter is designed AC priority by default. This means, when AC input is present, the battery will be
charged first, and the inverter will transfer the input AC to power the load.
The AC Priority and Battery Priority switch is available upon request. When you choose battery priority, the
inverter will inverting from battery despite the AC input.
