Benefits
Fuji Electric’s PWMAPR-M single-phase power regulator adjusts the power supply to industrial loads using pulse-width modulation (PWM) control with IGBT transistors. When combined with the included filter, this technology delivers a sinusoidal output voltage and maintains the load’s power factor. It is particularly well-suited for applications where power quality must meet thermal control requirements. The included display facilitates parameter setup and operational monitoring. The control modes allow the unit to be adjusted to the desired current, voltage, or power, while optional communication modules facilitate integration into an automated system.

A thyristor dimmer can adjust power by cutting off half-cycles at specific phase angles. The PWM-APR uses PWM modulation and a filter to produce a sinusoidal output. Our article explains the control principles of SCR power controllers to help you understand this difference.
The expected loads include resistive, inductive, and capacitive loads, as well as the primary-side control of transformers and rectifiers. Their compatibility must be verified with respect to the operating conditions and the device’s design specifications.
Yes. The PWM-APR power regulator comes with a filter suitable for the wire gauge and a setting indicator. Communication modules and certain control accessories are sold separately.
Yes, with the appropriate interfaces. The optional RPM003-AM and RPM003-AC modules enable Modbus RTU and CC-Link communication, respectively. They must be included in the selected configuration.
To maintain a temperature, the PID controller calculates the heating demand, and the PWM-APR power controller regulates the power supply to the load. Our guide explains how a PID control loop works and how the equipment works together.
