Autonics, SPR3 Series
Slim Three-Phase Power Controllers with LED Display
SPR3 Series
Brand:
The SPR3 series three-phase power controllers are ideal for installation in limited spaces with slim body sizes measuring only 105 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. With high power efficiency, the three-phase power controllers are ideal for various environments including power transmission and electric power distribution.

  • Slim and elegant design
  • LED display allows real-time monitoring of control input, load voltage, load current, load power, load resistance, and heat-sink temperature
  • Stable control with feedback control (constant current, constant voltage, constant power)
  • Communication output models available: RS485 (Modbus RTU)
  • Parameter configuration via PCs (RS485): Free device management software (DAQMaster)
  • Various alarm functions (alarm output) : overcurrent, overvoltage, heater disconnection, fuse break, heat-sink overheat, diode (SCR) error
  • Easy installation with mounting brackets
  • Easy fuse replacement and maintenance
  • High performance SCR (IXYS) diode
  • closed-loop

    Slim Size Measuring Only 55 mm Wide

    The SPR1 series power controllers are approximately 50% slimmer than similar models from other brands, making it easier to install in limited spaces.25A/35A/50A/70A models only
