 Features
1. High overload ability of our SKC charger is up to 300% rated power(20 sec.).
2. SKC 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).
3. Uses PFC(power factor correction) for charger, which has less power consumption than conventional units.
4. It has 15s delay before transfer when AC resumes, and overload protection when our SKC pure sine wave inverter equips with generator.
5. 10ms typical transfer time between battery and AC, which guarantees power continuity of SKC charger.Uses selectable input AC voltage (184-253V or 154-253V) for different kinds of loads.
6. Our SKC charger allows start up and through power with depleted batteries. Its powerful charge rate up to 90Amp**.
7. It can offer 3-step intelligent battery charging, and equipped with 8 preset battery type selector for totally flat batteries.
8. LCD status display, battery/AC priority switch, USB communication port are available for our APC 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.
