Why we need voltage guard ?
Violent or frequent voltage fluctuations (low voltage or high voltage) will certainly damage any refrigeration appliances compressor. The Unitec Voltage Power and Lightning Guard Sri Lanka protects your equipment’s by disconnecting the power when it goes below or above the 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.
Features:
- 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 5 Minutes: 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 fluctuation
- Digital Display to see the Working status: green for working (on), red for protection (off), yellow for time delaying (wait)
- 750C high temperature resistant and flame retardant enclose
- Domestic top brand high quality copper relay
