SPR1 Series

Slim Single-Phase Power Controllers with LED Display

The SPR1 series single-phase power controllers are ideal for installation in limited spaces with slim body sizes measuring only 55 mm wide. The LED display allows real-time monitoring of control input, load voltage, load current, load power, load resistance, and heat-sink temperature. The controllers feature phase control, cycle control, and ON/OFF control methods, with feedback control (constant current, constant voltage, constant power) option available for accurate and stable power control.
