The 2x4 Inch CUS250M Series: Effective Cooling and Maximum Field Life

TDK-Lambda introduces the 2”x4” footprint CUS250M series of AC-DC power supplies, that can deliver up to 250W. Target applications include medical, home healthcare, dental, test and measurement and industrial equipment. The new series has unique features that make it ideal for equipment developers, for end users and even for patients when used in medical devices. These features solve some of the main concerns in the industry: effective cooling, silent operation and maximum field life. Conduction and convection cooling in the CUS250M series enables silent operation. A unique output terminal / choke combination (patent pending) reduces common mode noise. A high-voltage bulk capacitor, used to store energy during short interruptions in AC power, is situated at the edge of the power supply PCB. This enables more effective cooling, and enhances reliability. Careful component layout on the underside of the PCB distributes heat evenly across the base, improving thermal transmission. The use of polymer output capacitors providing low ESR and high ripple current tolerance - to maximize field life. 12V and 24V models will be available initially, with 15V, 18V, 28V, 36V and 48V outputs following later. The output voltage can be adjusted by the user.
