requirements for long-duration peak currents to drive equipment such as printers and other electromechanical loads. The supply’s peak-power capability of 500 W offers reduced expenditure for companies, rather than implementing a power supply that is rated for continuous operation at more than 250 W. Operating over the –40 to +70 °C temperature range with derating above +50 °C, the series offers a typical high efficiency of 89% along with a very flat efficiency curve across the entire load range. The efficiency performance means less dissipated heat enabling a convection-cooled design and negating the need for system fan cooling. Supplied in a low-profile 1U-high chassis and 7.5 x 4-inch footprint and operating from a universal 80 to 264 VAC input, the series is available in three different models, respectively offering outputs of 24, 36 or 48 VDC. Other key features of the unit include constant-current overload characteristics, a 5V/1.5A standby output and a 12V/0.6A auxiliary output. Additional features include: remote sense, output inhibit, AC OK/Power Fail signal and the ability to current share up to three units in parallel. These features provide many options to the end system designer. Specific dimensions of the CMP250 series are 190.5 x 101.6 x 39.9mm; the series also comes in a covered version with dimensions of 200.5 x 104.6 x 48.8mm. Respective IT and medical safety application approvals for the series include: IT EN/IEC/UL60950-1 and EN/IEC/ UL62368-1; and ANSI/AAMI ES60601-1, EN60601-1 and IEC60601-1. The series also meets EN55032/11 Class B conducted and Class A radiated emissions. The ability to meet Class B radiated emissions is also possible with additional external components. The series is available from Digi-Key, element14, Farnell, RS Components, approved regional distributors, or direct from XP Power and come with a 3-year warranty.

Faster, More Flexible Probe from STMicroelectronics Eases STM8 and STM32 Programming on the Bench or in the Field STMicroelectronics has introduced the next-generation STLINK-V3 probe for programming and debugging STM8 and STM32 microcontrollers, adding enhancements to further increase flexibility and efficiency. Now featuring mass-storage support, a virtual COM port with multipath bridge, and three-times faster write performance, the competitively priced STLINK-V3 saves development time and easily reprograms devices in the field. In addition to providing typical JTAG/Serial-Wire Debug (SWD) and Single-Wire Interface Module (SWIM) connections, STLINK-V3’s Virtual COM Port (VCP) and multipath bridge allow communication through the microcontroller UART, I2C, SPI, or CAN interface, or GPIOs. This lets developers conveniently automate tests using custom control commands and observe run-time data on the host PC, or use the STLINK-V3 to program devices with a bootloader and simplify product maintenance. Major development tools already support STLINK-V3, allowing users to take advantage of the powerful features from within a convenient graphical environment such as the STM32Cube programmer and Integrated Development Environments (IDE) such as Keil® MDK- ARM, IAR™ EWARM, and GCC-based IDEs. ST also allows free access to STLINK-V3 low-level APIs, to facilitate integration with custom or automated test platforms. Supplied as a complete kit, the STLINK-V3SET contains the probe, debug connector, cables, and an adapter board that supports SWIM-specific features and provides access to signals from the multipath bridge. Users can further expand functionality cost-effectively with additional boards such as a voltage-translator module.
