Single-Phase Voltage Relays
A single-phase voltage relay is a device intended for effective voltage automatic control and such equipment as home appliances and other devices in homes and offices protection (disconnection). This process is required when the voltage deviates from the set values.
Voltage relay (single-phase) only performs the function of protection against voltage drops. When the supply network is worn out, single-phase loads distribution is not properly performed (due to the maintenance personnel low skills), as well as in case of “zero” disconnection or any other electricity network emergency, the device performs “consumer protection” by de-energizing in order to prevent the equipment failure.
Features:
+ Plug-in installation, small size, easy to install, no screw fixing
+ Suitable in the circuit of line voltage 220v ac, 60Hz or 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)
