Ultra Slim Power Controllers With Rapid Response


SOUTH BEND, IN - RKC Instrument announces two new power control series, the SSNP single phase control type, and the SSNZ for zero-cross control. Both series are a narrow 21.5 mm to allow for close mounting, either vertically or horizontally by Din rail mounting or screw mounting. The SSNP and the SSNZ are available in 15 amp or 25 amp.

Response to a setting input change is a rapid one cycle or less. Other functions include a ramp-up/ramp-down (soft start), auto-detecting power frequency which selects the power supply of 50Hz or 60Hz, and the series allows manual control.

The slim profile makes it appealing to both end-users and the OEM market in a wide range of industries including extrusion, semiconductor, test stands, environmental chambers, plastics, food, packaging, and heat-related processes.
