Functions & Features

• Provides a DC output signal in proportion to the deviation

(±5 Hz) from the center frequency (50 Hz or 60 Hz)

• DC output containing little ripple is ideal for computer

input

• No auxiliary power supply required

• Isolation up to 2000 V AC

• High-density mounting

• Conforms to IEC 60688

Typical Applications

• Centralized monitoring and control of power management

system in manufacturing facility or building

• Measuring frequency for UPS
