Offline UPS (Uninterrupted Power Supply) WK
Offline UPS (Uninterrupted Power Supply) WK
Applicationsof Offline UPS (Uninterrupted Power Supply):
Offline UPS WK is especially designed as the electric power supply of themonitoring equipments in various places.
Features ofOffline UPS (Uninterrupted Power Supply):
1. Modular type offline UPS:
our small size uninterrupted power supply is convenient for install andmaintenance;
2. High input voltage and low input voltage protection:
so the electric power supply product can work normally under the voltage rangeof 165-275V;
3. It can work normally even under frequency drift conditions;
4. Good load bearing ability:
this offline UPS adopted high quality power devices to enhance its load bearingability.
5. Good electromagnetic compatibility;
6. Shorter charge time and longer battery life:
our uninterrupted power supply adopted high power high frequency charger andadvanced charge method;
7. Variety of protections: protection for low voltage of batteries, overloadprotection, output short circuit protection,
anti-surge interference and lightning proof protections;
8. Unattended operation;
