For visualized heater control by programless communication
Select the optimal controller from our extensive lineup
- Wide range of basic functions
- Problem detection with various alarm functions
- With six-arm control, stability and control of even harmonics
PU23 _ Three-phase Power Controller accept input from a 4-20 mA DC signal, a manual setting device (PU20VR10), and other methods. The control method can be switched between phase control and zero-cross control by means of external contacts, communication, etc. Types of phase control include constant voltage, constant current, and constant power, in addition to the basic type (no feedback), each of which can be selected according to the characteristics of the applicable heater.
Extensive product lineup
Power control methods include basic, constant voltage, constant current, and constant power. Frequency-division control is supported. An appropriate model can be selected according to the characteristics of the applicable heater. The PU23 _ of power controllers covers a wide range of current ratings from 10 to 500 A and a wide range of voltage ratings from 200–440 V AC in the case of PU23 _ .
Abundant options for expansion of functions
Options include heater burnout alarm and current restrictions. A communication function (RS-485/Modbus) is available if a model with a setting and display unit is selected.
6-arm control (PU23 only)
The PU23_ Three-phase Power Controller uses 6-arm control as a standard feature, making it capable of stable control performance even with transformer primary side control. It is also effective in reducing even harmonics.
Visualization of heater control by programless communication
By using PU23 _ power controllers in combination with the CMC15G communication controller (sold separately), it is possible to programlessly communicate with host devices such as a PLC. By transferring data such as output voltage, output current, output power, and heater resistance, it is easy to "visualize" heater control.
