The RISH Master 3490 DS by Rishabh Instruments is a dual-source digital energy meter designed for monitoring electrical parameters from both utility and generator sources in three-phase and single-phase networks. Housed in a compact 96×96 mm DIN panel mount enclosure, it features a high-brightness dual-line 7-digit LED display for simultaneous viewing of utility and generator parameters. The meter supports true RMS measurements up to the 15th harmonic and offers optional MODBUS (RS485) communication and pulse outputs for integration into energy management systems.
