The single-phase power regulator PU21 series is a compact / lightweight single-phase power regulator with high panel mounting density.
It is possible to switch between phase control and frequency division control by using external contacts or communication.
In addition to the basic type (without Fordback), constant voltage type, constant current type, and constant power type are available for phase control, so you can select according to the characteristics of various heaters.
It is also possible to suppress harmonics and operate by selecting frequency division control.
The communication function can also be used by selecting the option setting / display unit. In addition to various settings, it is possible to read the output voltage, current, power, and heater resistance value.
When combined with the communication controller CMC15G, programless communication with higher-level devices is possible.
