LP-FM Frequency Transducer

LP-FM Frequency Transducer

The LP-FM mains frequency transducer converts an ac voltage signal into a dc output signal which is proportional to the frequency of the input signal.

Frequency: 45 - 55Hz or 48 - 52Hz (other on request)
Burden: 1mA @ Vnom
OutputLoad independent dc current and voltage
(others on request): 0 to 10mA dc <1500Ω load
: 0 to 20mA dc <750Ω load
: 4 to 20mA dc <750Ω load
: 0 to 5V dc >2kΩ load
: 0 to 10V dc >2kΩ load
Accuracy: Class 0.5 to IEC 60688
Power Supply: 24V, 110V, 230/240V ac ±20%, 1.5VA
