Monitoring of battery energy storage systems (BESS)
The battery symmetry monitor UH 9830 from the VARIMETER series monitors battery energy storage systems (BESS) that are used in particular in the area of emergency power supply or power generation. The device monitors the battery symmetry with a centre tap. By splitting into two strings with the same number of battery blocks, voltage differences and thus the failure of a single battery cell or a single block are recognised directly and reported as a fault. With four switchable DC measuring ranges, the UH 9830 can be adapted to a wide range of applications for battery voltages up to DC 1000 V.
– Configurable for common battery / accumulator voltages
– Wide auxiliary voltage and temperature application range
– Large battery voltage ranges up to DC 1000 V
