Excerpt
The compact EMpro DC energy meter enables the space-saving, precise, and tamper-proof direct measurement of currents and voltages of up to 650 A/1,000 V DC. The DC energy meter fulfils the accuracy-class-B (EN 50470-3) without the need for an additional current transformer. With an overall width of just 107.2 mm, the product requires a space of just six horizontal pitches (HP) on the DIN rail. The product allows the signing of the meter values and time synchronization of the meter. Due to it´s heatsink with integrated shunt measurement it operates in a temperature application range from -40°C to +80°C. Thanks to the built-in RS-485 interface with SLIP-Protocol and the approval in accordance with German calibration law it can be used for billing purposes.
