Quick Details
Specifications
This Broyce Control 45UFR electrical relay unit is designed to monitor the frequency of its own supply. The 45UFR is used for monitoring under frequency conditions, whereby the relay de-energises when the frequency drops below the adjustable trip point. The relay re-energises when the frequency increases above the trip point plus the hysteresis.
Detects Under frequency
UFR relay de-energises if frequency falls below trip level – red LED on, contacts 11, 14 /21 & 24 closed
Adjustable trip level
Adjustable hysteresis
Monitors own supply
1 x DPDT relay output 8A
LED indication for supply and relay status
DIN rail housing
Write on identification tab
Dimensions: H78 x W45 x D99mm
