Single-phase power regulator (thyristor unit SCR) SSNP/SSNZ
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.
■Thin design
Both 15A and 25A have a thin design with a width of 21.5mm.
■Can be mounted closely
Up to 8 units can be mounted closely together. The width is 172mm.
*When mounted closely, the ambient temperature characteristics will change.
■Soft start and soft down functions are standard equipment.
Even if the input signal changes suddenly, the output changes slowly, suppressing inrush current.
■Manual control possible
Manual control is possible with an external volume.
