Rack-mounted Power Transducers 17-RACK

FREQUENCY TRANSDUCER

Functions & Features

• Providing a DC output signal in proportion to deviation (±5

or 10 Hz) from center frequency (50 Hz, 60Hz or 55 Hz)

• DC output containing little ripple is ideal for computer

input

Typical Applications

• Centralized monitoring and control of power management

system in manufacturing facility or building

• Measuring frequency for UPS
