D91‑W Active Power measurement

General

The D91-W is a compact digital AC active power meter with a 5‑digit red LED display. It measures active power from 0 to 30000W with 1% ±2 digits accuracy. The display automatically switches format: below 10000W it shows 0.0‑9999.9W, and above 10000W it shows 10000‑30000W. The meter features a built‑in current transformer (CT) for non‑invasive measurement — simply pass the conductor through the CT hole. Voltage measurement inputs are connected via rear terminals. It is ideal for power monitoring in industrial, commercial, and residential applications.
