LTHZ

Power Transducer Series LT-UNIT

FREQUENCY TRANSDUCER

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
• 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
