MULTIFUNCTION CURRENT RELAY

The current relay is designed with a micro-controller.With programmable range, function and timing it can be programmed to cover all kinds of applications.
The monitored current is fed through an internal shunt with a voltage is then amplified in a balanced amplifier, rectified, averaged and compared with a preset reference voltage.AC and DC current between 1 mA and 10A can be measured directly.By means of a current transformer or a shunt resistor the range can be extended without limits.
