Electric Power Regulator

Electric Power Regulator Electric Power Regulator

Catalog

High performance unit with network function

Our thyristor type power regulator is reliable and easy to operate, making it widely popular across many industries. We have been developing and manufacturing semiconductors and thyristors, core elements of power control, for many years and with constant reliability, allowing us to deliver high quality power regulators.
The "UF series", fruit of many years of experience, is equipped with our thyristor module (Isolation type) in the main circuit to make it light and compact. It increases accordingly the mounting density and fits a large number of units on the control panel. The control circuit uses digital control. Various protective functions and options are available to achieve great performance. The lineup also includes the general-purpose SPU series.

CALPOTE  High performance type 「UF-1 series」Single phase type: UF 1 / 25-1200A

CALPOTE High performance type「UF-3 series」Three phase type: UF 3 / 25-1200A

Supports open field network

Our products are the first in the industry to incorporate open network communications such as CC-Link. You can enable interconnection with control devices such as PCs and PLCs, and easily match the equipment with mechanical systems. No need to develop complex programs or special boards, just connect via communication protocols such as RS232C. (Some models are not compatible.)

  • As an option, it is possible to connect up to 63 units on the same communication unit instead of individual connections.
  • The signals and monitoring of the output voltage, current and power can be set from a PC.

Possible to produce heater control panel

We take advantage as an integrated factory of our capabilities, and produce products from sheet metal to bus bars and harnesses. We can also manufacture a heater control panel integrating the peripheral circuit of power regulator and many units.
