SSRs streamline design with extra, integrated functions

Crydom has integrated additional microprocessor-controlled features into four families of Solid State Relays (SSRs) for applications up to 90A and 530V AC, delivering ease of design, compactness and cost savings.

All devices share a common package outline to simplify board layout.

The Crydom MCTC series integrates a temperature controller featuring short-cycle compressor protection. Only a J- or K-type thermocouple and a 32mA DC source are required for closed-loop temperature control. Five temperature ranges are available.

By integrating a phase-angle controller alongside the SSR, the MCPC series provides a complete phase-fired logic system and also integrates a snubber network. No calibration is required.

For applications requiring gradual power application or shut-down, MCS series variants provide adjustable softstart, soft-stop or soft-start/soft-stop options. Ramp times are remotely adjustable from 100ms to 10 seconds.

The integrated burst-fire controller on-board the MCBC series supports 0-100% adjustment and provides two time-base periods for smooth proportional control. AC-phasedetection circuitry allows connection to only one side of the load, simplifying installation.
