Description
AR438 module helps with interconnection, power supply and load switching, monophasic and triphasic, adding the current measurement capability up to 10A.
Enable input helps for a safe relay disconnection. It is a quick electrical -hardware- disconnection of the relays and is designed to be an auxiliary safety element, so that loads cannot reach the device under test.
The average current is measured with a 10mOhm shunt resistor.
Each power relay has two independent cycle counters for total cycles and dangerous short cycles.
