Eltako DSZ16DE-3x100A Three-Phase Energy Meter, Direct Measurement, Uncalibrated, 100 A

In a busy commercial building, the facility manager needs to track electricity consumption across three-phase circuits without the complexity of MID-calibrated meters. The Eltako DSZ16DE-3x100A is a direct-measuring three-phase energy meter that installs on a DIN rail and provides clear LCD readings of active energy (kWh). With a maximum current of 100 A and a nominal voltage of 3x230/400 V AC, it handles typical sub-metering tasks in distribution boards, workshops, and server rooms. The S0 pulse output enables remote data logging, while the backlit display ensures readability even in dim electrical cabinets.

Why choose it

This meter offers a cost-effective solution for energy monitoring in three-phase installations where legal calibration is not required. Its direct measurement capability up to 100 A eliminates the need for external current transformers, simplifying installation. The S0 pulse output integrates easily with building management systems or data loggers, and the backlit display provides at-a-glance consumption data.

Ideal use cases

• Sub-metering in commercial and industrial buildings
• Monitoring energy consumption of individual machines or departments
• Integration into energy management systems via S0 pulses
• Retrofit projects where a simple, reliable kWh meter is needed

Good to know

The DSZ16DE-3x100A is uncalibrated, meaning it is not intended for billing purposes subject to legal metrology. It is designed for internal energy monitoring and cost allocation. Installation requires a 4-module DIN rail space and standard three-phase wiring. The meter operates on a single tariff and does not support multi-tariff functions.
