GOSSEN GMC Instruments EM2289 trojfázový elektromer 80 A MID, DIN lišta, LCD, S0 impulzný výstup (U2289-V039)

The EM2289 from GOSSEN GMC Instruments is a three-phase energy meter for direct connection up to 80 A, engineered for MID-compliant billing applications. Unlike many meters in its class, it combines a compact 4-module DIN rail housing with an easy-to-read backlit LCD and an S0 pulse output for remote reading, making it equally suited for sub-metering in commercial buildings or integration into energy management systems.

Highlights

• Direct measurement up to 80 A – no current transformers required
• MID conformity according to EN 50470-1/3 for billing-grade accuracy (Class B)
• Backlit 7-digit LCD for clear reading even in poor lighting
• S0 pulse output (1000 impulses per kWh) for connection to building automation or data loggers
• Wide operating temperature range from -25 °C to +55 °C

In daily use

The meter is designed for permanent installation on a DIN rail and measures active energy (kWh) in three-phase 230/400 V networks at 50 or 60 Hz. With a starting current of just 20 mA, it reliably registers even very small loads. The front of the housing meets IP51, so the display is protected against dust and dripping water; the terminals are rated IP20. Power consumption is less than 0.5 W per phase, keeping the meter’s own energy draw negligible.
