Industrial Three Phase AC to AC Combined Solid State Relay


MGR-AH_3 Series

Panel Mout Solid State Relay


The MGR-AH_3 Series Three Phase Industrial AC to AC Solid State Relay is not a stand-alone device, but consists of three MGR-AH Series Single Phase industrial AC to AC solid state relays, a heat sink, a 85℃ temperature controlled switch and an air-cooled fan; so, it is also known as...


Basic Parameters

Control Voltage:  85~265VAC

Control Current:  Ultra low input current, ≤30mA (in parallel), ≤10mA (in series)

Load Voltage:  Three phase 30~1200VAC

Load Current:  100A

Mounting:  Combined with three MGR-AH series single phase DC to AC solid state relays, a heat sink, an air cooler radiator and a temperature control


Reverse-parallel SCR as the output component can be used in commercial or heavy industrial applications with reliable performance

"Ultra low" input current

Low output off-state leakage current

Low output on-state voltage drop

Display output status via LED

Standard output RC snubber circuit

Industrial radiators and axial fans use standard shapes and materials for excellent heat dissipation

Over-temperature protection


If the load current is 10A, a heat sink must be equipped; if the load current is 40A or more, an air-cooled radiator or a water-cooled radiator must be installed.

When the load is an inductive load, be sure to connect a varistor in parallel with the output terminal, whose voltage value is 1.6-1.9 times the load voltage.
