When added to an MGE UPS SYSTEMS static transfer switch, the synchronisation unit guarantees seamless transfers under all conditions

> For configurations with different types of sources
> Dependable transfer and reliable operation
> Easy installation, set-up and use
> Small size

Operating modes

> "Automatic-source" mode is used when the frequency and phase of both sources can be controlled.
> "Fixed-source" mode is used when only one of the sources can be controlled or when more than two sources must be synchronised.
For example, for three independent sources, two synchronisation units are required and must be set to "fixed-source" mode.

Operating principle

The unit synchronises a number of sources connected upstream of static transfer switches (STS).

• It may be used to synchronise:
  > Galaxy and Galaxy PW UPSs;
  > heterogeneous sources (other UPS brands, transformers, engine generator sets, etc.) when the frequency and phase of at least one of the sources can be controlled.

• The controllable sources can be:
  > Galaxy PW UPSs in both single-unit and parallel versions;
  > Galaxy UPSs in single-unit versions or parallel versions with a centralised bypass.

Reliable operation and ease of use

> The UPS output voltages are monitored and the unit also runs internal checks.
> If power fails or phase displacement occurs, an alarm is issued (LED and dry contact) and a status report is displayed on the UPS screen.
> Dry contacts remote the following information:
- Sources out of phase;
- Source 1 controlled;
- Source 2 controlled;
- Major fault.

Dependable transfer

The unit synchronises the voltages of independent sources under all operating conditions, even the most critical, including:
> loss of power on the UPS bypass AC source;
> phase displacement on the UPS Normal AC source;
> UPSs operating on battery power, etc.
