The instrument is mounted on DIN-rail (6TE) and features RS-485, USB, Ethernet communication interface, four universal input/output terminals, and additional input for Pt100 temperature sensors. It is a robust solution for harsh and challenging environments of a typical smart grid deployment with measurement category CATIV/300V and wide industrial temperature. Optionally it offers a color LCD. Large 512MB internal storage memory logs all the measured data locally.
BC 235 with proper hall sensors can analyze DC components, the standard 5Hz-2.5kHz, and optionally supra-harmonics in the range between 2 and 9 kHz. It has a sampling mode DC-500, which is also suitable to analyze standard industrial variable frequency drives frequency (VFD, adjustable speed drive controllers).
It can also monitor power quality (with PQ-S or PQ-A module) – inter-harmonics, flicker, voltage events, record transients (with GO module), and the ripple control signals (RCS module). To the standard power quality monitoring application, the BC 235 can add an advanced ability also to detect DC current components in the measured AC network and thus analyze the influence of the DC appliances or power sources on the quality of the AC side of the distribution grid.
