  • Pro-E workstations
  • Project management
  • Prototype area
  • Software development

Control Systems

As a leading manufacturer of power sources for the US military, our specialty is developing custom microcontroller-based systems built for the harshest military applications.

Case STudy

Precise control of air flow, temperature, and fuel flow was needed to control the reforming process of JP-8 for fueling a fuel cell with hydrogen. Dewey developed the control boards and firmware to accomplish this.

We engineer controls for: power generation systems, fuel reformers and fuel cells, power converters, hybrid power systems, and all-around internal test equipment.

Control systems that meet the challenge

The Dewey Electronics engineers continually design and develop control system improvements to ensure our equipment performs on today’s challenging battlefields, including extreme temperature environments. We’ve manufactured large-scale applications such as mountain-wide snowmaking systems that operate in severe winter weather, and miniaturized controls for fuel cell reformers operating in high temperature environments.

Our generator controllers, from analog systems to fully digital controllers, deliver optimal performance, thanks to battery monitoring and charging, remote monitoring and controlling, auto start, and data logging and diagnostics.

Analog control systems

  • Analog computers (Navy speed and distance indicator)
  • MEP-501A and MEP-531A generator controllers
  • Mk 48 battery charging modules

Digital control systems

  • Generator micro-controllers
  • Battery monitoring and charging systems
  • Fuel cell reformer control systems
  • Microgrid controllers

Controls for power systems featuring:

  • Inverters
  • Power converters
  • Voltage regulators
  • Permanent magnetic generators
  • Current limiting power regulators
  • Variable frequency motor controllers

Remote control capabilities such as:

  • Remote control boxes for generator control
  • Remote controls for vehicle auxiliary power units
  • Data bus outputs such as RS-323, CAN, Mod Bus, IP protocol, and more

Rapid Prototype Development

At Dewey Electronics, we understand that no government agency can afford to wait a year or more for prototype development and delivery.

Case Study

Hunter Defense Technologies approached Dewey Electronics with an urgent need for a customized 2kW generator. Deliveries were critical, and only a small quantity was required.
Dewey Electronics Services Engineering Rapid Prototype Development
Thanks to our dedicated prototyping factory assembly area and hands-on engineering team, Dewey has an established track record of designing, creating, and delivering prototype hardware in production quantities, in just weeks or months. The technicians, assemblers, and engineers of our rapid prototyping center are prototype development experts who turn engineering sketches, breadboard hardware, or customer “napkin drawings” into finished prototype hardware—including custom-built models to support critical needs for such clients as the USMC, US Army, HDT, Lockheed Martin, STS International, and US Tower.

Low Rate Initial Manufacturing

Confidence in structural integrity and reliability is key in manufacturing all military equipment.

Case Study

The US Marine Corps contracted Dewey Electronics to provide a new battery charging Auxiliary Power Unit (APU) to power the IED Defeat System that was being installed on the Logistic Supply Vehicle. The quantity was significant and the delivery schedule critical. The design had to transition from prototype to LRIP seamlessly.

The first step in manufacturing is taking designs from prototype stage through low rate initial production (LRIP) before going into full production cycles.

Dewey Electronics deliver tactical power solutions for deployment in even the most austere environments.
Dewey Electronics has extensive experience in managing and successfully transitioning designs through LRIP and first article testing.

Dewey’s production capabilities include:

  • Welding
  • Electro-mechanical assembly
  • Automated factory acceptance testing
  • Hot room test facilities
  • Reliability and endurance testing
