About our Dual Input Power Supplies

Our dual input power supplies are designed for unique applications that require to operate from either a DC voltage or AC voltage source. As with our industrial grade supplies, these are able to operate in adverse weather condition and extreme temperature ranges. This platform was designed for single phase applications that require a wide AC input voltage range (90 to 264Vac) and wide DC input voltage (36 to 72Vdc for 48Vdc nominal or an optional 18 to 36Vdc for a 24Vdc nominal input.

This “DI” series employs a high efficiency, power factor corrected, temperature resistant, ac to dc rectifier module to provide an isolated front end for this series. The IFE incorporates an EMI filtering section designed to meet EMC Directives for emissions under EN55022, CISPR 22 Level B and FCC Class B. Also incorporated into the front end is transient and surge protection designed to meet Immunity requirements under 55024. The back end utilizes high efficiency, dc to dc converters to provide the regulated DC output(s). This design allows us to easily change outputs to meet differing applications, essentially, a tailor made power supply for the OEM without the expensive NRE charges.

One note with this dual input power supply design is that it can be offered as an open-frame PCB for the OEM to deploy it into their chassis. As with all our high-rel power supply series, this unit is also conduction cooled via baseplate and can reliable operate at full rated power with a baseplate temperature from -40°C to +85°C. This approach allows the OEM flexibility to control where and how it will be cooled.

Other options can include mounting the dual input power supply module into u-channel or enclosed chassis including an IP67 ingress rated chassis for improved weatherproofing. Our typical power range for the DI series is 100 watts to 300 watts, mostly single output. As with all of our series, this is high configurable power supply and can be easily modified to meet other industrial applications. As a special note, we have built a 1640 watt dual input version that we recently delivered to Goddard Flight Systems. The details can be found on our semi-custom / modified standard products page.
