VS-30 Voltage Stabilizer (30 HP 230V), UL Certified by Phase-A-Matic

230V Phase-A-Matic™ Voltage Stabilizer (Instruction Sheet)

• The normal input operating voltage of the Rotary Phase Converter is 208-230V on the 230V (“R”) series, 460V on the 460V (“RH”) series. The generated phase output voltage of a 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 230V (“R”) series, and greater than 460V on the 460V (“RH”) 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.

• A Rotary Phase Converter, Voltage Stabilizer combination, when properly sized, provides the necessary voltage balance of close to + 5% or less between legs compared to standard 3-phase line voltage of + 10%. It also helps to keep the output voltage stable during peak loads, thus helping most CNC / PLC and other voltage sensitive equipment to operate properly.

• Running 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 only. Consult factory.

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

• Supplied in a NEMA type 1 enclosure with various sizes of knockouts.

• Intended for indoor use only, but can be placed in a rain-tight enclosure for use in wet or damp applications.

Important: Voltage Stabilizers are not to be used as a stand-alone product. They are meant to be paired only with our Rotary Converters and DO NOT allow you to regulate voltage beyond factory settings. For more information, please read the Start Here document.
