Phase-A-Matic VS-50 VS Series 50 HP Voltage Stabilizer, 230V, UL Certified

IMPORTANT: Voltage Stabilizers are not to be used as a stand-alone product. They are meant to be paired only with Rotary Converters and DO NOT allow you to regulate voltage beyond factory settings.

For use with Rotary Converter for 3-phase electronic equipment such as CNC/PLC machines, AC/DC drives, and all voltage-sensitive equipment. Provides +/- 5% voltage stabilization.

The normal operating voltage of the Rotary Phase Converter is 208-230VAC on the 220V "R" series Rotary Converter. The generated phase output voltage of the Rotary Phase Converter is normally higher than the input voltage under no load and light load conditions. In applications with high single-phase voltage (greater than 230V on the 220V "R" series), the no load or light load output voltage may be excessive. Some CNC/PLC equipment will not work properly at the higher output voltage.

The Phase-A-Matic™ Voltage Stabilizer is designed to reduce this higher voltage to nearer the input voltage. It will also keep the output voltage stable during peak loads, thus helping CNC/PLC equipment and other voltage-sensitive equipment to operate properly.

Running very small motors alone on a Rotary Converter that is 3 times larger (or more) may not reduce the output voltage sufficiently, in which case the smaller motor may run hot. For these cases, to reduce cost it may be possible to use a dedicated Voltage Stabilizer sized to the requirements of the problem motor or load only. Consult factory.Supplied in a NEMA type 1 enclosure with various sizes of knockouts.

Intended for indoor use only in dry locations, but can be placed in a rain tight enclosure for use in wet or damp locations.

Select a Voltage Stabilizer at least as large as the load it will operate. It does not have to be as large as the Rotary Phase Converter being used.
