Protection

Surge Protection & Noise Filtering

EMI / RFI filters at input & output side

Tripping when sparking at load side / ups output with in 20 mili sec i.e one cycle.

Tripping when short-circuiting at load side / ups output with in 20 mili sec i.e one cycle.

Input AC over voltage (up to 600V) / Under voltage/ Auto recovery no damages to UPS & load

DC Over voltage/Under voltage, Over Temperature. Over Current for Rectifier

Output over voltage, under voltage

Output overload , Short Circuit

Over Current for Rectifier

Isolation Transformer at output side

Switch Gear

MCB for mains, MCB for Battery,
UPS circuitry works as protection breaker for Load
Highly sensitive and operates with in 1-2 cycles

Audio Alarm
