ES-2970 Rev.1
17HZ
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
