Description:
The AcuDC 262 is an advanced, revenue-grade DC power and energy meter with one voltage input (12–1000Vdc) and two independent current inputs, allowing two DC circuits to be metered and billed from a single unit. Certified to IEC 62053-41 Class 0.5, it measures bi-directional energy per channel and in total, includes cable loss compensation, electronic and physical anti-tamper seals, and three data loggers plus a trend logger. With Modbus RTU over RS485 and Modbus TCP/IP over Ethernet, it targets EV charging, data centre PDUs, battery storage and renewable DC systems.
Key Features:
Revenue-grade accuracy: IEC 62053-41:2021 Class 0.5
One voltage input (12–1000Vdc, 0.1%) and two independent current inputs (0.2%)
