SATEC VRM – Voltage Ratio Module for DC High-Voltage Applications

The SATEC VRM (Voltage Ratio Module) is a DC voltage step-down accessory that extends the measurement range of SATEC PRO Series meters (HACS model) in high-voltage DC applications. While the PRO Series meter can directly measure DC voltages up to 820V, many modern DC systems – particularly solar PV arrays, Battery Energy Storage Systems (BESS), and EV fast-charging infrastructure – operate at bus voltages up to 1,500V DC.

The VRM bridges this gap by providing a calibrated voltage division, allowing the PRO Series meter to accurately measure the higher DC bus voltage without modification.

Specification

  • Input voltage: up to 1,500V DC
  • Output voltage: up to 820V DC (PRO Series meter compatible)
  • Powered directly from the DC bus being measured

Applications

  • Solar PV – string and inverter DC bus metering at 1,000–1,500V DC
  • BESS – Battery Energy Storage System DC bus monitoring
  • EV Charging – DC fast charging station metering

Compatible With

  • SATEC PRO Series meters (HACS model): PM335-HACS, EM235-HACS

Mounting

  • DIN-rail mount (35 mm standard)
