New Power Controllers Products

Power Controllers are available in 15 A or 25 A versions.

SSNP single-phase control type and SSNZ series for zero-cross control are narrow 21.5 mm to allow for close DIN rail or screw mounting, either vertically or horizontally. Response to changing input setting is one cycle or less. Functions include ramp-up/ramp-down (soft start), auto-detecting power frequency that selects power supply of 50Hz or 60Hz, and manual control.
