The IM3 is a simple energy-only (kWH) single-channel meter housed in a plastic enclosure complete with a display unit. Can be configured as a single or three-phase meter in three available voltages: 120, 208, and 240 volts. The IM3 uses 100 mAmp current transformers and is also equipped with a pulse frequency output that can be interfaced to an external pulse counting device. Every purchase of an IM3 includes three 100:0.1A/200:0.1A current transformers (CTs)!
