The smallest 1U Height, 320W AC/DC power supplies available. These safety approved supplies feature power factor correction, autoranging AC inputs, robust filtering, 100 kHour MTBF and four mechanical options.

Universal Voltronics’ line of BRC switching power supplies are notable for low ripple, fast transient response, endurance to repetitive arcing and stable output even in the face of line voltage and load charges. Power is converted using advanced IGBT’s switching at frequencies above 20kHz, and controlled using tuned pulse width modulation techniques.

The new A8698 and A8697 from Allegro MicroSystems Europe are the latest additions to the company's range of step-down regulator ICs.

HiTek Power has introduced the OL6000/803, an 80kV power supply for applications ranging from ion implantation to electron-beam welding to particle acceleration. The robust new supply is housed in two 4U high, 19-inch rack-mounting chassis weighing a total of 80kg, making it one of the smallest and lightest in the industry for its output.

Texas Instruments Incorporated today introduced several new battery management integrated circuits (ICs), including its next-generation Impedance Track™ “gas gauge” chipset, to improve battery performance and protect multi-cell, lithium-based battery packs used in notebooks and other systems.

Linear Technology Corporation introduces the LTC4085, a monolithic autonomous power manager, ideal diode controller and standalone battery charger for portable USB devices. The LTC4085 features PowerPath™ control that provides power to the USB peripheral device and charges the peripheral's single-cell Li-Ion battery from the USB VBUS or a wall adapter power supply. To comply with USB current limit specifications, the LTC4085 automatically reduc...

LEM has introduced the TT series of compact split-core AC current transformers. These new devices feature an innovative type of core material, enabling this technology to be the first to offer high performance coupled with an attractive price. The core material used in the transformers is a new type of ferrite with improved magnetic permeability, allowing the accurate measurement of AC signals in a extended frequency range that includes 50/60Hz. ...
