Genesys programmable power supplies with Power Sink option

Energy recovery is an important issue for all types of electrical installations with electric motors. A change in voltage or current at the output of the power supplies during a braking action can result in tripping and even failure of the power supply source. Another task no less important is simulation of different voltages. Modern TDK-Lambda's Genesys series power supplies successfully meet the challenges due to the Power Sink function.

BMS increases battery life time

The era of the Internet of Things and Big Data imposes new requirements and sets stringent standards for computer power supplies. A large number of computers and other powercritical IT equipment concentrated in data centers can no longer be supported by using the traditional non-smart UPS. In such cases the BMS systems - one of which is described in this article - can be helpful.

CRANE Electronics DC/DC-converters: radiation test results – an exam is passed

One of the most important tasks of building spacecraft with a long active life is to ensure the required resistance of the on-board equipment to ionizing radiation effects. The article addresses general issues on the development of the converters for space use, gives a brief overview of the results of a test of the radiation-hardened DC/DCconverters commercially available from CRANE Aerospace & Electronics (Interpoint™) for their resistance to single event effects. Such tests were held when preparing the modules for use in the onboard equipment of the Mars Science Lab, Curiosity. Also included are the results of tests for resistance to ionizing dose effects when exposed to low-dose-rate and low-intensity gamma radiation which are present in some components of DC/DC-converters with a two-switch structure. The article is based on information provided by CRANE Aerospace & Electronics.
