The V180 is a single-width VME module that allows accurate and comprehensive measurement of AC power circuits. The V180 acquires powerline current and voltage inputs using approved current transformers and model C750 remote potential transducers. Up to sixteen CT sensors and eight potential connections (six lines plus two neutrals) can be accommodated: each CT may be combined with any potential pair to form sixteen virtual wattmeters. Each metering channel can acquire line voltage, current, true power, volt-amps, power factor, and kilowatt-hours; for polyphase circuits, multiple channels may be aggregated for power, KVA, power factor, and KWH measurements, allowing metering of up to six delta or four wye-connected 3-phase circuits simultaneously. All V180 measurements are true RMS. Power and KWH measurements have a usable dynamic range of over 10,000:1, allowing even small power flows to be resolved on high-current feeders.

The V180 includes eight digital I/Os that can be programmed to count or produce KWH pulses and +-5V analog input (12-bit resolution) capability. The on-demand waveform sampling option acquires real-time waveforms of any current and voltage pair, allowing detailed waveform examination and Fourier analysis of line harmonics. Temperature (RTD) and BTU measurement option also available. Accessories include a C760 field wiring termination panel, C750; 120-to-480-volt potential transducer unit and current transformer from 5 to 1200 amps.

The equivalent instrument is also available as an ISA PC-plugin module, the Highland Model AT180.
