Battery symmetry monitoring relay is designed for continuous monitoring of the battery voltage relative to its medium point and sending an alarm in case of voltage symmetry distortion
Front view
The relay offers the following capabilities:
- battery symmetry monitoring
- determination of asymmetry polarity of the two battery halves
- output relay contacts control: generation of “dry contact” signal in case the asymmetry of the two battery halves exceeds the setting
- monitoring of two battery parts with 17 battery cells
- local LED alarm
The relay is manufactured in a unified plastic enclosure with front connection of conductors. The device shall be mounted on the DIN-rail. The asymmetry setting for the two battery halves is selected using the switch on the front panel
