Features

Standard Heavy-Duty and High-Low Double Horsepower Rated

NAPCco offers two different static phase converter models to choose from. Our Standard Heavy Duty (SPC) is a robust static phase converter and has your classic horsepower ranges. Our High-Low Double Horsepower Rated (HL) models are two (2) Standard Heavy-Duty Static Phase Converters built into one. The HL model has a high and low horsepower range setting. The setting is easily selected by a toggle switch on the front cover of the unit.

Runs most motors at two-thirds power

A static phase converter uses motor start capacitors to start a 3 phase motor on single phase power. These capacitors are disconnected once the motor reaches full RPM. The motor continues to run on the 2 single phase lines of power. Two-thirds of the motor windings are being energized, producing approximately two-thirds of the motors power.

Easily accessible wiring junction box

Top mount junction boxes are easily accessible, making wiring a snap and can be completed in minutes.

Universal mounting options

Our static phase converters include hanging brackets that allow for wall or machine mounting.

High Voltage Rated Start Capacitors (330V)

High voltage rated start capacitors can withstand higher surges of voltage without failure. The capacitors are also mounted with bleed resistors to help discharge heat and voltage in the capacitors. These resistors help extend the life of the components.

Digital / Electronic Motor Starting Relay

All NAPCco converters have a motor starting relay that is a digital/electronic phase converter. The patented differential voltage sensing circuit knows precisely when the motor is up to speed and when to disconnect the starting circuit. This is the same digital motor start relay used in our Pro Line Rotary Phase Converters. Additional built-in features include over-voltage protection and safety time out.

Robust Start Circuit

Heavy duty relays and contactors are used to tolerate the high amperage flow during start up. We use enlarged components because we want this unit to last as long as your machine does.
