Why we need voltage guard ?
Violent or frequent voltage fluctuations (low voltage or high voltage) will certainly damage any refrigeration appliance?s compressor. The Power Guard protects your equipments by disconnecting the power when it goes below un-acceptable level.
Additionally, there is a delay when power returns to normal. This will ensure that the appliances is not switched on-off repeatedly during fluctuations nor it subjected to a massive surge normally experienced when power returns after power cuts.
+ Plug-in installation, small size, easy to install, no screw fixing
+ Suitable in the circuit of line voltage 220v ac, 50Hz under rated power
+ Protector cut off power supply at once for exceeding the over voltage, and recover automatically 30s later after circuit back to normal
+ Automatic recovery delay time 30s: ?prevent additional damage to the electrical appliances due to frequently switch on and off caused by the unstable voltage
+ Protector also cut off power supply at once for voltage sag
+ Working status indicator: green for working (on), red for protection (off), yellow for time delaying (wait)
+ 750?C high temperature resistant and flame retardant enclose
+ 0.7mm thick beryllium bronze
+ Domestic top brand high quality relay
+ All chip in Taiwan and USA imported original brand
+All motor drived equipments
+Protect the home appliances?against the damage of low voltage, Surge, Spike, etc.
