Boston, MA, April, 2025

Potomac Electric is proud to introduce the PEA733 family of DC servo drives — modern, high-performance replacements for legacy products originally manufactured by Westamp, Servodynamics, Gettys, Glentek, GE HIAK, Cleveland Machine Controls, Performance Motion Control, and others.

As many legacy DC servo drives become obsolete, the PEA733 provides a reliable, direct Form, Fit, and Function replacement — extending the life of your critical equipment without the need for expensive system redesigns.

PEA733 DC Servo Drive Features and Benefits:

• From 20A to 40A continuous current
• 115V/230V single-phase AC input
• 230V three-phase AC input
• Current, velocity, or position control loop options
• Accepts digital or analog command signals
• Compatible with resolver, tachometer, and encoder feedback devices

The PEA733 replaces large DC servo drives for applications in many industries such as:

• CNC machines — DC servo drive replacements for precision manufacturing equipment
• Radar and antenna systems — reliable replacements for aging DC motion control systems
• Medical equipment — modern servo drive upgrades for critical healthcare devices
• Industrial automation systems — extend system life with a high-performance DC motor drive

Designed for flexibility and performance, the PEA733 ensures seamless integration into existing legacy systems, delivering modern control capabilities while minimizing downtime and system costs.

The PEA733 family of DC servo drives is proudly designed and manufactured in the USA at our factory in Boston, Massachusetts. This guarantees exceptional quality, faster lead times, and technical support you can count on.
