PT-330 Digital Phase Converter-10hp (w/Plasma Display)

Weight: 83.00 lbs

Phase Converter with Plasma Display-10hp (PT-330D) - In stock for local pickup! Recommended for the small to mid-sized commercial business, especially with any load sensitive CNC equipment. This model includes a Plasma Display with 36 Character Text for Status Indicators (text display includes advanced diagnostics). This makes troubleshooting and discussions with the factory much easier should a problem arise.


Phase Perfect® produces true sinusoidal three-phase output voltages balanced to within 1% under all load conditions. Because the output voltage is a sine wave with very low harmonic distortion, all types of three-phase equipment can be safely powered. Input current is true sinusoidal, near unity (.99) power factor and does not produce harmonics which can pollute the power grid.


Phase Perfect® can safely power virtually any three-phase application within its rated capacity. It can power resistive and capacitive loads as well as motor or inductive loads. Its power quality makes it ideal for powering demanding loads such as CNC machine equipment, submersible pumps and other voltage sensitive applications.


Phase Perfect® is available with built-in contactor and adjustable solid state overload relay, which allows it to function as a motor starter for most single-motor applications. It also has a control circuit and terminals, which allows an external switch to control both the converter and the load. Installation is straightforward and simple and can usually be accomplished in minutes with a minimum of additional equipment required.


Phase Perfect® converters handle regenerative power by passing clean, balanced power back onto the single-phase line when three-phase loads are in a generating mode. Most other power switching converters waste regenerative power by burning it up with braking resistors. Putting regenerative power back onto the line saves electrical power and even allows Phase Perfect® to operate continuously as a three-phase to single-phase converter.


Utility three-phase service can cost thousands of dollars to install, even when three-phase lines are nearby. Phase Perfect®is an affordable alternative that provides better phase balance than most utilities will specify for their service. It also protects three-phase equipment from damage due to under-voltage, over-voltage and single-phasing that can occur with AC mains power. Phase Perfect® is rugged, reliable and typically 97% efficient.
