Does your equipment require exceptional thermal performance with low noise, adjustable output voltage, active current sharing, low leakage current, and Class B conducted and radiated EMI?
The IMA Series and MEB Series stand out as some of the most high-end single-output medical grade power supplies available in the market. With an output power capacity of 1000 W and higher, they incorporate up to two variable-speed fans that effectively manage power supply temperature without producing unbearable noise. These power supplies offer adjustable output voltage and active current sharing, providing greater flexibility for end system design and development. Their low leakage current and adherence to conducted and radiated EMI Class B standards contribute to enhanced safety and EMC at the system level. The new IMA-S2000 PLUS and MEB-1K5A48T also excels with high peak power to support the start-up of electromechanical components like fans and motors. Carrying both medical and ITE certificates makes them suitable for a wide variety of systems.
