The WM1-DIN27AAD0XX is a 3-digit multi-range microprocessor meter produced by WEG Germany. It has the scrolling display function of power, energy, power factor (cos ϕ), current and voltage, and can automatically select the k (kilo) or M (mega) scale. It also has the function of automatic peak value measurement, and has dual measurement inputs: 5A or 27A. In addition, the housing of this meter is easy to mount on a DIN rail and offers an IP40 protection rating.
The WM1-DIN is a DIN‑rail mounted power analyzer that measures voltage, current, power, energy, power factor and peak values. It offers multi‑range input (up to 5 A or 27 A), automatic scaling, and optional programmable alarm setpoints, pulse output and RS‑485 serial interface.
The manual provides detailed input and output specifications, front‑panel description, wiring diagrams for single‑ and three‑phase connections, and step‑by‑step programming instructions. Safety information, protection rating (IP 40) and environmental limits are also included.
