From the VFD multi-display reading are V,A, VA, W, Var, WH, etc. more than 30 power and energy parameters. Via the RS 485 Modbus, communications, including the instant maximum and minimum of all parameter, maximum demand control, time stamping, etc. more than 90 parameters can be achieved by remote monitoring system.
This power meter can replace many units of conventional analog or digital instruments and change over switches (e.g. Amp, Volt, KVA, KW, PF, KWH, KVarH, FQ etc.). This saves on the wiring material usage and reduces the cost on metering needs.
