Insulation monitoring · IMDIn an IT system, live conductors are not directly connected to earth. Behaviour during the first insulation fault is assessed alongside the system configuration, leakage capacitances and protection arrangement.Read the product group guide ↗
Residual current monitoringDetecting sinusoidal AC, pulsating DC and smooth DC components requires different sensor and evaluator configurations. Choose A/F or B/B+ according to the application's current waveform.Read the product group guide ↗
Communication and central monitoringInterfaces such as BMS, BCOM and Modbus are selected according to the product's supported architecture. Do not assume every device supports every protocol.Read the product group guide ↗
