Key Features

Minimizes impact of external magnetic fields to reduce false alarms.

Dramatically improves signal to noise ratio for high dependability.

Simplifies installation and allows application to a wide variety of bus bar sizes.

24V logic reverse alarm output

Latching reverse alarm output with LED indication and manual reset button

Two user adjustable over current alarms with dry contact relay outputs

Power relay for direct activation of protection equipment

Dramatically simplified as compared to BCMR

BRP Versions

BRP: Sensor pair with 24V signal output including 30m signal cable and connector

BRP L: Sensor Pair + Latching function Module. Adds output signal latching and LED indication to the reverse current detection function. This ensures that users are able to identify which specific rectifier caused the reverse current trip, which must be manually reset before continuing. DIN rail mount.

BRP PE: Sensor Pair + Latching & Over Current Module. In addition to BRP L latching functions, each with their own dry contact relay output. DIN rail mount.

Optional Power Relay

Special high-power, electro-mechanical relay to provide reliable switching of higher power loads, particularly those controlled by 120VDC. This optional relay can be directly driven by the BRP reverse current signal in all versions as well as the lighter duty over current relays in the BRP PE version. DIN rail mount.

Optional Universal Power Supply

Provides the main 24V DC power required by all BRP systems in applications where 24V DC is not already available.

Optional IP67 Enclosure

For protecting BRP Modules , Power Relays and Universal Power Supply when installed in demanding environmental conditions
