Energy measurement for 120 to 480 VAC Simultaneous measurement of 2 AC mains networks plus 2 additional voltages For multifunctional measurement tasks Intelligent mains synchronization unit The module has a compact size and combines a power measurement module that has special features with a synchronization unit that is able to meet all demands.

The measurement unit's 3 current inputs are suitable for both X: 1 A and X: 5 A current transformers.

Overcurrent resistance and the high resolution of the measurement unit round off its features.

For the voltage inputs, the value range can be configured between 480 VAC and 120 VAC .

The area of use includes 4-wire AC networks with a phase voltage up to 480 VAC and 3-wire systems, whereas L2 can be grounded (V-connection).

The module can also handle Aron measuring circuits.

The resulting measured values include the pure phase current; line-to-line voltage or phase voltage; the effective, reactive and apparent power parts; the mains frequency; the power factor and much more.

In addition, peak values and energy meters are stored on the module in nonvolatile memory.

Depending on the configuration, it is also possible to use a digital output as a pulse encoder for an external energy meter.

The synchronization unit doesn't just take the phasing and phase voltage into consideration; integrated intelligence also monitors the rate of change and other parameters, allowing them to influence when the synchronization output is switched.

It is also possible to monitor a generator using a large number of additional conditions.

A total of 4 voltage inputs provide substantial overall flexibility.

Monitoring functions expand the features of the module.

Dependent overcurrent monitoring is included, which utilizes the thermal capacity of the motor/generator to allow short overloads while still providing full protection.

The dependent, delayed imbalanced load monitoring used to protect three-phase generator and three-phase networks from imbalanced load can be adapted to the characteristics of different generator types using parameters while taking their special thermal time constants into account.
