Rack-mounted Power Transducers 17-RACK

POWER FACTOR TRANSDUCER

Functions & Features

• Providing a DC output signal in proportion to power factor

• DC output containing little ripple is ideal for computer

input

Typical Applications

• Centralized monitoring and control of power management

system in a manufacturing facility or building

• Measuring power factor for a motor
