Feature of Satec Multifunction Meter
Multifunction Three-Phase Power Meter
- For direct connection to the power line or via potential and current transformers, there are three voltage inputs and three current transformer-isolated AC inputs.
- Volts, amps, power, power factor, neutral current, frequency, imbalanced voltage and current, and true RMS
- Ampere/Volt demand meter with measurement capabilities at 25, 50, 60, and 400 Hz
Energy Meter for Billing/TOU
- IEC 62053-22, Class 0.5S Four-quadrant polyphase static meter for both reactive and active energy
- Active, reactive, and apparent energy counters; three-phase total and per-phase energy measurements
- Eight tariffs, four totalization and tariff energy/demand registers, four seasons, four sorts of days, eight tariff adjustments each day, and a one-time, simple-to-programme tariff calendar schedule
- Automatic daily profile log for total and tariff registers for energy and maximum demand
Instantaneous Waveform Recording
- Real-time waveform monitoring in “scope mode”
- Six-channel simultaneous one-cycle waveform recording at 64 samples per cycle
Din rail mounting or Panel mounting optional
