Frequency Relays
We manufacture a wide range of Frequency Relay which has been precisely
fabricated under the supervision of our technical experts. These are
meant for continuous monitoring of the line frequency which is compared
with highly stable internal crystal based frequency to achieve
error-proof result. In case the line frequency goes out of the range
selected, status after the SET time delay is changed.
Special Features
Under and Over Frequency relays with calibrated linear scale
Smart design to fit on any standard mounting channel
Choice of screw less terminals
2% Accuracy
Total wireless interiors
Test and Auto/Manual Reset facility
Ideal for DG set applications
Designed for high reliability, as relay energizes only under fault conditions
