Solid State Relay - CUSTOM 2PH, 150A to 2700A

Load......Normal Resistance, MWIR, LWIR
Input......DC Logic (SSR), 4-20mA, 0-10Vdc
Firing......Zero Crossing, Burst
Voltage...24Vac to 690Vac Supply

 

The CUSTOM solid state relay range comprises one, two and three phase models with currents up to 2700 amps at 690Vac.

Equipped with microprocessor control, the CUSTOM-2PH solid state relay can be run as a solid state contactor, acting as an on/off switch with zero volt turn on and zero current turn off. Alternatively they may be operated as a zero cross burst firing controller with output proportional to either a 4-20mA, 0-20mA or 0-10V DC control signal.

These robust & rugged SSR's are primarily intended for OEM industrial electrical heating applications and can be customised for customer specific requirements. The CUSTOM-2PH power controller is suitable for constant resistance, long-wave infrared and medium wave infrared loads. Internal semiconductor protection fuses are supplied as standard. A heater break alarm with internal current sensing is available as an option for the detection of partial or total load failure. The Custom solid state relay range can also be utilised with the REVO-PC power management system.

Note: 2PH units are suitable for switching 2 legs of 3 phase loads and are suitable for all 3 wire (no neutral) resistance type loads.
