APR (AC Power Regulator)
PWMAPR-M

PWMAPR-M

Handling area：North America, China, Europe

AC power regulator featuring Fuji Electric’s proprietary PWM (pulse width modulation) control method and sine wave output

  • Saves energy by not deteriorating the load power factor

  • Eliminates need for harmonic countermeasures

  • Capable of being used as a stabilization power supply thanks to its sine wave output

  • Applicable to the capacitive loads of capacitors, etc.

Comes standard with voltage limiting function effective for lamp loads, etc.

Enhanced functionality by coming standard with a setting indicator (based on in-company comparison)

Configurable feedback methods for ACR, AVR, and AWR, as well as gradient settings

Includes slots for various communication units and analog and digital I/O boards (optional)

Supports Modbus RTU, CC-Link, etc.
