Three-phase power regulator PU23 series is a compact / lightweight three-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.
Since 6-arm control is adopted, high-quality power control is possible while suppressing harmonics compared to 3-arm 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.
