Electronic Active and Reactive Energy Meters

• Professional energy meter for 2, 3, 4 wire systems with 65 A direct connection or 1 A, 5 A transformer connection
• Accuracy class B for commerce and industry and for enhanced requirements in private households
• Cost savings thanks to initial calibration ex factory, per MID, conformity evaluation procedure for modules B+D
• Configurable multifunctional versions for the acquisition of reactive energy and measured line quantities
• Indication of installation errors: phase sequence, phase failure, transformers with reversed polarity, overload
• Universal pulse output with adjustable pulse rate, pulse duration and selectable voltage range
• Flexible communication via integrated LON, M bus or L bus interface
• Possibility to maintain full functionality via fail-safe 24 V auxiliary voltage system even if disconnected from the mains
• Cover can be sealed, parameter configuration lock
• Quality product „Made in Germany“

The calibrated energy meter can be used to acquire and bill active energy in industrial, household, commercial and building management applications.

Relevant values are transmitted to data logging, billing and optimizing systems, as well as to building automation and control technology applications, by means of a pulse output, or via LON, M-Bus or L-Bus interface.

Installation itself is extremely simple because the meter detects connection errors, which are indicated immediately. Maximum convenience is assured by displaying active power, which provides immediate information regarding momentary circuit load. If more information about the electrical system is required, functionality is simply expanded.

Particularities

Multifunctional Variants – Additional Parameters

Depending on the type of multifunctional variant, the meter is also capable of acquiring reactive power and displaying up to 26 additional measured quantities.

As a result, voltage level, utilization of individual phases, reactive power component and the functioning of compensation systems can be evaluated at any time by simply pressing a button without any additional measuring equipment.

Extensive Initial Calibration at the Factory

The meters comply with the MID directive which is valid throughout Europe and in Switzerland, and are shipped with initial factory calibration. They can be used immediately for billing purposes. Lead-times and costs are reduced as a result. Conformity assessment is conducted in accordance with modules B and D, and a declaration of conformity is included in the operating instructions.
