SL Power Electronics has launched a series of 425W, single-output AC/DC power supply. Designed for test and measurement, the TU425 series boasts a robust protection including electromagnetic compatibility (EMC) and electromagnetic interference (EMI) compliance, and surge immunity.

The devices have an active current share for redundant applications, and provide 300W of convection cooling or 425W with moving air. It has an operating temperature range of 10C to 70C. It will start-up at a low -40C, providing optimum thermal performance and bypasses a heating element. Compliant to heavy industrial levels of the IEC61000-4 standards for EMC immunity and Class B Conducted EMI with 6db margin, the power supply series features over 350,000 hours Mean Time Between Failure (MTBF) and uses long life electrolytic capacitors in its design.

The models under the series have a universal AC input of 90V to 264V, and are available in outputs of 12V, 18V, 24V, 48V and 56V. They provide input and output monitoring alarms, in addition to isolated 12V/1A fan output and 5V/2A standby voltage.

The devices are available at $155 each in OEM quantities.


The TU425 series addresses the power requirements of all types of test equipment including oscilloscopes, analysers, test boards, chromatography mass detectors as well as industrial process control systems that require clean, reliable power for the highest level of performance. Source: SLEP
