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.

Details

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

Bright LED Display

The 3-digit, 7-segment LED display allows real-time monitoring of control input, load voltage, load current, load power, load resistance, and heat-sink temperature without requiring connection to an external display device.

Feedback Control Option

The SPR1 series power controllers support cycle control, phase control, ON/OFF control methods with option for constant voltage, constant current, and constant power feedback control with ±3% output accuracy. The controllers can handle various types of loads including nichrome, molybdenum, and silicon carbide.

Various Functions

The power controllers feature various operation functions including Soft Start, Soft Up/Down, Input Correction, and Input Slope Correction. The functions allow safer operation, load protection, and accurate power control.

Various Alarm Functions

Error messages (displayed on screen) and alarm indicator (ALM) will blink simultaneously and notify the users if there are operation errors such as diode error, overcurrent, overvoltage, fuse break, heat-sink overheating, or heater disconnection.

Simple Fuse Replacement

The fuse in the power controllers can be replaced easily just by removing a few bolts.
