DynAmp BRP
The new, BRP rectifier protection system is a specialized modular system designed to sense reverse and over current events on high current DC bus bars. This next generation system is Dynamp’s next-generation technology developed to replace the older BCMR systems. BRP utilizes a pair of sensors, mounted on opposite sides of the DC bus bar. These advanced sensors incorporate 30 years of experience and new proprietary magnetic shielding technology to dramatically improve signal to noise ratios and practically eliminate chances of false alarms.
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
