Convection-Cooled Modular Power Supply Delivers 600 W

16 June 2016

Excelsys Technologies has announced the CoolX600 Series of convection-cooled modular power supplies, which produce a 600 W output without using fan-assisted cooling. The CoolX600 Series offers system designers conversion efficiencies of up to 94% and comes in a compact 8.5 x 4.5 x 1U package. The completely user-field-configurable CoolX600 Series allows customers to configure and reconfigure without voiding the warranty or affecting safety.

Designed to meet both medical and industrial global safety specifications at 5,000 meters altitude, the CoolX600 Series can exceed 93% efficiency even in harsh, remote applications subject to input voltage line surge disturbances of up to 300 VAC. In addition to achieving 600 W output with fan-less natural convection cooling at up to 40° C ambient with no derating, the series can enhance thermal performance using system fans or external conduction cooling. This increases system reliability and results in system lifetimes that are typically 25% longer than the system lifetimes of competitors. For harsh environments, the CoolX600 Series offers high-input surge protection of 4 KV and reverse energy protection without using blocking diodes. It also offers a 25 W standby power output as a standard feature to effectively provide another output for system intelligence, cooling fans, display and so forth, which increases flexibility.

The CoolX600 Series features <300 uA leakage current and full safety certifications to UL/EN60950 and UL/EN60601 for industrial and medical applications. Medical certifications include IEC60601-1-2 4th edition (EMC), BF (Body Floating) rating, dual fusing and 2 x MOPP. For industrial certifications they include EN60950, EN62386-1, ISO9000 and SEMI F47 and, for defense and aerospace applications, they include MIL810G and MIL461 certification and CE101/102. The supply carries a five-year warranty.

The power supplies allow for analog and digital management with PMBus monitoring and control capability. They are user-field-configurable with plug-and-play modules. All outputs are isolated and may be connected in series or parallel to achieve higher output voltages or currents. Mounting options include base, side and DIN-rail alternatives.

List price for the supply is $290 each in OEM quantities with delivery of 8 to 10 weeks ARO.
