Application Notes

Dual Channel Monitoring for DC Power Systems

Date: February 10, 2026

The AcuDC-262 Application Note highlights the dual-channel 1V/2I architecture enables efficient monitoring of modern DC power systems by measuring two independent current paths with a shared voltage reference. Designed for multi-branch DC applications such as solar PV, EV charging, telecom power, and DC PDUs, it reduces wiring complexity, saves panel space, lowers integration costs, and delivers synchronized, high-accuracy power and energy monitoring across multiple circuits.

Key Highlights

  • Supports applications for PV string monitoring, DC EV charging, telecom, and DC power distribution
  • Reduces overall integration costs compared to conventional single-circuit DC metering
  • Dual channel 1V/2I architecture for efficient multi-branch DC monitoring
  • Supports 0 - 1000 VDC measurement for ±100 mV shunt, 4–20 mA, and ±5 V Hall effect sensors
  • Delivers 0.2% current accuracy compliant with IEC 62053-41 Class 0.5
  • Real-time current, power, energy, demand, and ripple factor for system diagnostics, and load balancing
