Automatic Voltage Regulators
With the addition of new United States Embassy sites going in all over the world, Gilbert Electrical Systems along with a representative from Systems Control Associates, Inc. have worked closely with the US State Department in developing a specification for metal enclosed voltage regulators. Enclosing voltage regulators in a metal housing along with the proper bypass switches and fused disconnects not only provide security in a hostile environment but also gives the user a turn key project for system regulation.
Voltage regulators can be thought of as a step autotransformer. Normally, by control sensing, these regulators step the voltage up or down in increments when the system voltage becomes to high/low. By doing so you provide a clean steady source of power to the transformer feeding the loads. This not only protects your load but it also helps to protect the transformer from stray voltages and transient currents.
