Power meter
8 I/Os | V180VME
Highland Technology, Inc.
FEATURES
- Measures up to sixteen AC power circuits
- Measures true RMS amps, volts, watts, KVAs, kilowatt-hours, and power factor
- Interfaces to up to sixteen current transformers
- Highside: lowside potential inputs freely programmable using any combinations of potential connections
- Pulse counting and KWH pulse output capability
- Analog input capability
- Waveform acquisition option
- Temperature (RTD) measurement option
The V180 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. 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.
