Battery monitoring
Benefits of our battery monitoring relays
- Precise voltage monitoring of individual batteries or entire strings
- Early fault detection in case of over- or undervoltage
- Alarm for DC ripple and charging issues
- Safe detection of defective batteries
- Suitable for both mobile and stationary systems
Battery monitoring
Battery monitoring - reliable detection of faults in battery systems
Avoid costly downtime, damaged batteries and failures in your DC system with efficient battery monitoring. Our range of battery relays are designed to monitor battery voltage, detect faulty batteries and send a battery alarm in case of failure - before the damage happens.
The relays ensure that batteries in e.g. UPS systems, stationary or mobile energy storage are not exposed to overcharging, deep discharge or abnormal DC ripple. This makes them ideal for both emergency power systems and demanding industrial installations.

Voltage monitoring
BMWB
Over- and undervoltage (window) - BMWB
Combined over- and undervoltage relay. Using a built-in switch mode supply, designed to monitor levels from 14-340 VDC. The individually adjustable hysteresis for over- and undervoltage means that the relay can be used both for switching equipment on and off with defined voltage values. BMWB can be used as a window discriminator with well-defined upper and lower limit values.
Advantages:
- 2 x C/O relay outputs, can be combined or used individually
- Precise upper level/return and lower level/return adjustment
- DIP switches for setting over- and/or undervoltage or window function
- LED indication of input state, relay state and timing state
BMCD
Battery over and under voltage - BMCD
BMCD triggers alarms both in
in case of discharge and overcharging.
Advantages:
- Programmable to 12, 24, 48 or 110 VDC
- OFF delay 0-10 s or 0-100 s
- Relay functions: Undervoltage: 1 x C/O and 1 x N/C Over- and undervoltage: 1 x C/O, 2 x N/C and 1 x N/O
- LED status indication
Battery symmetry
BMSA
Battery symmetry and voltage - BMSA
The relay can be used with the same or different batteries connected in series.
The individual cells in the batteries must be identical.
Advantages:
- Complete unit, multi-range 24-512 VDC
- No leakage current through the center point
- Adjustable delay, ON and OFF
- Relay functions: Balancing: 2 x C/O Balancing and over/under voltage: 3 x C/O
DC ripple
BRIA
DC RIPPLE - BRIA
The relay measures ripple in DC supply. It is ideal for monitoring the quality of the smoothed DC output voltage in AC/DC converters, from both single phase and three phase AC.
Advantages:
- One device for all supply voltages from 18-360 VDC
- 4 adjustable subranges for accurate detection from 0.4 % to 6.4 % of nominal voltage (Un)
- Consistent sensitivity despite varying ripple frequency between 30 and 3000 Hz
- Relay function: 2 x C/O (activated by % ripple in relation to set voltage)
