ConTech Announces 40W 1 x 2" DC-DC Converter with a 2:1 Input

ConTech, a Division of Calex, announced the "TMH" Series of dc-dc converters. The TMH Series offers up to 40W of fully regulated output power with an industry standard 2 x 1" footprint. The series offers a 2:1 input range with nominal input voltages of 12, 24, and 48Vdc. Single outputs offered are 3.3, 5, 12, and 15Vdc. Dual outputs are ±12 and +/-15Vdc.

The TMH Series operates with efficiencies as high as 92%. Features include Remote On/Off, Output Trim, and Short Circuit Protection. The operating ambient temperature range of the TMH is -40 to +55°C with no de-rating. The non de-rated temperature range can be extended to 65C ambient with an optional heat sink. The unit is encapsulated with a thermally conductive potting compound in a six-sided metal case for improved thermal performance in still air environments. The TMH series is RoHS compliant.

Energy Efficiency with Class D Amplifier Modules

Class-D switching amplifiers are helping audio designers create personal multimedia devices and home audio/visual systems that demonstrate how compact and stylish equipment can also deliver high sound quality and high audio output power. The key to this breakthrough, providing freedom from the large and bulky boxes housing traditional audio products, lies in the class-D amplifier’s high energy efficiency, which is typically around 90%. This allows designers to reduce or eliminate heatsinks as well as using smaller-sized PCBs and smaller components such as transformers, connectors and power supplies.

The Role of Hall Effect Sensors in Power Distribution Infrastructure

Power distribution units (PDUs) form an essential part of modern computing and data communications hardware. They provide multiple outputs for transferring electrical power with maximum efficiency, controlling the power capacity and safeguarding against the possible causes of supply interruption. With an ever increasing need from tech savvy consumers for higher data throughput and greater quantities of data storage capacity, as well as tough international legislation now governing CO&sub2; emissions, the demands being placed on these units are proving challenging for engineering teams to satisfy.
