Battery monitoring, battery control & voltage monitoring
Monitor DC Voltage on batteries and DC supplies. Minimize the risk of deep discharging, or overcharging in UPS, stationary battery equipment and mobile battery equipment. Includes an alarm function in case of faulty batteries or charges faults.
Thiim A/S offers a variety of battery relays for general and customer specific solutions.
Battery low voltage monitoring relay
The BMCA battery voltage relay is designed to measure battery voltage for under voltage.
The relays are Programmable for 12V, 24V, 48V or 110V battery systems, and can be set by DIP switch.
Install to avoid deep discharging, or overcharging in UPS, stationary battery equipment and mobile battery equipment. Alarm function in case of faulty batteries or charges.
Battery high/low voltage monitoring
The BMCD battery voltage relay is designed to measure both battery voltage for under voltage and over voltage.
The relays are Programmable for 12V, 24V, 48V or 110V battery systems, and can be set by DIP switch.
Install to avoid deep discharging, or overcharging in UPS, stationary battery equipment and mobile battery equipment.
Alarm function in case of faulty batteries or charges.
Universal DC voltage monitoring relay
BMWB is a combined over and/or under voltage relay.
The voltage relay is designed for precise monitoring of a wide range of DC voltages from 14V to 340V.
With a build-in high efficiency switch mode power supply, the BMWB is able to cover the whole measuring range without the need of an external supply.
The BMWB can by means of dipswitches be set to work as a relay for monitoring under voltage and over voltage with two individual C/O contacts, or the contacts can be paralleled and the BMWB be used as a window discriminator relay where both C/O contacts are in the powerless position outside the window.
With the paralleled relays the BMWB can be set to only register under or over voltage.
For Voltage monitoring in UPS, stationary and mobile battery installations.
Battery symmetry monitoring relay
The multipurpose BMSA is designed to monitor and give an early warning if one or more cells are performing different from an average cell in the battery.
The battery must consist of two blocks of cells coupled in series with an accessible middle point used as a reference potential. No current will be drawn from the middle point.
The Symmetry Relay monitors that the positive and the negative battery blocks perform equally independent of the actual charge and load level. The two battery blocks do not need to be of equal voltage (same number of cells), but the individual cells must be equal and have the same history.
The BMSA accepts up to twice as many cells in one block as in the other. The nominal voltage range of each block can be set from 12V to 256V and the actual voltage must be within the range of 9 to 300V allowing a battery voltage ranging from 18V to 600V. For high battery voltages exceeding 300V the middle point connection is critical.
The BMSA is used on batteries in back up supplies where, by matching two batteries against each other, a warning can be given as soon as a cell in one of the battery blocks starts to deteriorate.
As the BMSA is not depending on the actual charge and load status, it is a powerful supervision of only occasionally used batteries in emergency systems.
