Three-phase power regulator (thyristor unit SCR) THW-A
RKC INSTRUMENT
About This Product
■What is a power regulator (thyristor unit SCR)?
This is a device that inputs analog signals such as 4 to 20 mA and continuously and finely adjusts the power supply to the heater. You can choose between the phase control method that controls the power waveform and the low-noise zero-cross control method that controls the power cycle. With the phase control method, by using the soft start function, it is possible to control the primary side of heaters and transformers with large inrush currents.
■Excellent responsiveness and reproducibility with digital control
- Digitally controlled operation device equipped with a display and setting keys on the front.
・With a 1 second setting for soft up (soft start)/soft down, the response is quick and can handle high-speed temperature rises.
■Available for heaters with special characteristics
Constant voltage control, constant current control, and constant power control are possible, so it can be used with heaters whose resistance value changes greatly depending on temperature changes, such as noble metals (platinum/molybdenum), superkanthal, and silicon carbide.
■Equipped with a wide range of functions as standard
Abundant functions such as external contact input, soft up (soft start)/soft down, manual/automatic switching, slope setting, output limiter, output bias, input-phase angle proportional/input-voltage proportional/input-power phase angle proportional switching is equipped as standard.
*Other product numbers are available.
