About
Control Technology Inc.

Control Technology Inc. has been manufacturing quality standby/uninterruptible power supplies and power converters since 1978. Our first product, trademarked RBS=DC were DC to DC converters which using battery power, allowed uninterrupted operation of Apple II computers when the primary AC power source failed. In addition to protection from AC power source failure, these products allowed Apple II computers to be used for remote and mobile applications where AC power was not available.

Control Technology Inc. Supplies to Military OEMs:

• Ruggedized UPS
• COTS UPS
• Military UPS
• Ruggedized Power
  Conditioners
• COTS Power
  Conditioners
• Ruggedized DC-AC 
  Inverters
• COTS DC-AC Inverters

In 1983, CTI introduced a series of reserve standby power supplies, using a DC to AC inverter for critical equipment which required AC power. These products, trademarked RBS=AC, gave AC powered equipment the same benefits that the RBS=DC products gave to the Apple II computer: power failure protection and the possibility of remote and mobile applications. CTI’s patented designs allowed for a wide range of highly efficient and reliable models with power ratings of 300 to 1500 watts which use a variety of battery packs to meet a wide range of customer holdup time requirements.

In 1988, CTI made the successful transition from reserve standby power systems to online uninterruptible power supplies (UPS ) by developing four models of UPS/ power converters to meet the ruggedized requirements of the U.S. Army. Many of these units featured a universal power input which allows AC power input over a range of voltages and frequencies covering all AC standards or nominal 28 volt DC power input, such as the output of a HUMM-V alternator, or both. In addition, the UPSs accepted power input from internal batteries when the other sources of power failed.

Over 2,000 units of one of these earliest models (4200 series) were deployed with the U.S. Army for the CHS1 Standard Tactical Battlefield Computer System. Later, improved units (4300 series) were supplied to the U.S. Army for the CHS2 program, some for the U.S. Army Tri-BAND tactical satellite communications link, and others for the Node Management Terminal system. The versatility of CTI UPS/ power conditioners made them ideal for installation in HUMM-V based systems or in mobile command shelters.

By constant improvement of the efficiency of our units, we have been able to increase output while maintaining the same package size for our units. We have also developed our own proprietary intelligent battery data system which is able to predict battery hold up time dynamically with changing loads and battery behavior. This commitment to quality and constant improvement has allowed CTI to become a mission critical supplier to Lockheed Martin and Raytheon for the (THAAD) anti missile system. CTI’s willingness to modify existing product or create new ones engineered to meet a client’s specific needs is one of our greatest assets.
