In a new and high-performance IP20 housing to the size of a standard “hockey puck” relay, this phase angle power SSR makes the voltage output vary with the analogue input voltage. Consequently the power applied to the load is proportional to the input. More precisely, thanks to the control logic performed by a micro-processor, power is a linear function of the input (proportional to U²).
In this small housing, the new series of relays switches from 35 Amps to 125 Amps. The standard output cage terminals can accept 2 AWG8 wires for currents up to 2 x 50 Amps or AWG0 wires thanks to a special adaptor kit allowing up to 151 Amps!
Products are available with a 4 to 20 mA, 0 to 10 VDC or potentiometer inputs.
In addition, the relay output is protected against transient over- voltages with a varistor, whilst the input/output isolation and input to baseplate isolation or output to baseplate isolation is 4 kV complying with the EN60950/VDE0805.

This new generation of proportional controllers comes also in “celpac” housing (ready to use – 22,5mm pitch).
