RPS-120S Series Medical Power Supply


RPS-120S Series Medical Power Supply

MEAN WELL’s latest generation of medical PCB power supply, the RPS family, was well-received by the market and the demands for miniaturized PCB type medical power supplies continue to increase. As a response, MEAN WELL is expanding the RPS family’s 3” x 2” product offering to 120 W, up from 30 W ~ 65 W of the previously released RPS-30/45/65, by releasing the ultra-high-power density RPS-120S series.

The RPS-120S series is the only medical grade 3” x 2” PCB type power supply on the market that can operate up to 120 W under free air convection. The maximum power rating achieved by other 3” x 2” PCB type power supplies is 100 W without external fan cooling. Other features of the RPS-120S include a 2xMOPP isolation level suitable for use in type BF applications, 150 W peak load capability for 10 seconds, a -30°C ~ +85°C operating temperature range, no-load power consumption <0.3 W, 94% high efficiency, and operating altitude up to 4000 meters. In addition, the RPS-120S is compatible with both Class I (with FG) and Class II (no FG) installations, making the power supply suitable for installation in both plastic and metal enclosures and can save the system designer time and cost on EMI debugging. The RPS-120S is suitable for all types of medical applications that require low leakage current and low standby power consumption, such as medical diagnostic equipment, blood analysis instrument, medical monitoring equipment, and more.
