Quality AC/DC and DC/DC Power
Supplies Where Performance and
Reliability is Critical
Cosel has been manufacturing quality AC to DC switch mode and DC to DC power supplies since 1969. With our commitment to quality, reliability, and customer service, backed by a documented field failure rate of under 100 PPM, Cosel has been the dependable and cost affective solution for over 35 years. When quality is a must, reliability is critical, and on time delivery is crucial, Cosel stands alone.

Cosel's AC/DC and DC/DC power supplies fall into 5 affordable categories. The first category is the Unit Type - a series of AC/DC switching power supplies that come standard with a metal chassis for mounting. The second category is the Rugged PCB Type - an AC/DC switching power supply type that can be mounted with or without a chassis. The third category is the AC/DC On-Board Type - a series that is designed for mounting directly onto a PCB. The fourth category is the DC/DC Brick - the DC/DC brick comes in the industry standard full, half, quarter, and eighth brick dc power supply models. The fifth category is the DC/DC On-Board Type - an un-encapsulated dc converter supply, available with or without a cover, and designed for mounting directly onto a PCB.

As a vertically integrated manufacturer, Technology Dynamics Inc. has the ability to control all aspects of our products in house. We provide custom engineering for the design and packaging of our products through the modification or custom design of PC boards, transformers, and sheet metal.

While many companies offer consumer products “modified” or “ruggedized” for certain applications, TDI’s products are designed from inception for harsh environment Commercial, Industrial, and Military applications. Many of TDI’s products have been successfully qualified to Military Environmental Standards such as MIL-STD-810, MIL-STD-167, MIL-STD-901, MIL-STD-461, and MIL-STD-1399, with still on full-time active duty after 35+ years in the field!

Robust construction and extremely high reliability are features inherent to TDI’s products, which all feature very low MTTR and high MTBF figures. Equally as important, standing behind each product with the TDI nameplate is a company with over 30 years of experience in the engineering design and quality manufacturing of truly rugged power conversion equipment and systems. – the same rugged power conversion equipment and systems trusted by all of the major Defense Prime Contractors, all branches of the American DOD (and US-Friendly Defense Departments worldwide,) and industrial firms the world over in the most demanding applications in existence.
