The MQ9310ET280 dc-dc converters are a new generation of isolated, very high efficiency DC/DC power modules providing up to 3.6Adc output current at a nominal output voltage of 28Vdc in an industry standard, DOSA compliant 1/8 brick size footprint, which makes it an ideal choice for high voltage and high power applications. The MQ9310ET280 modules have typical efficiency of 93% at full-load and nominal output voltage of 28V. The maximum output ripple of the module is 20mVRMS, which helps to reduce external filtering capacitors and system cost. The output is fully isolated from the input, allowing versatile polarity configurations and grounding connections.
