LHZ

Power Transducer Series L-UNIT

FREQUENCY TRANSDUCER

Functions & Features
• Providing a DC output signal in proportion to deviation (±5 Hz) from center frequency (50 Hz or 60 Hz)
• DC output containing little ripple is ideal for computer input
• Isolation up to 2000 V AC
• Highdensity mounting
Typical Applications
• Centralized monitoring and control of power management system in manufacturing facility or building
• Measuring frequency for UPS
