94% Efficient power supply offers 340W without forced air cooling

by | Jul 13, 2022 | Enedo, Industrial, Press release

The DDP460 series of Industrial power supplies with their compact form factor and high efficiency that the marketplace demand, provide up to 460 W of regulated DC power in a 3.0” x 5.0” footprint. The open frame compact package facilitates system integration and thermal management in space constrained and closed environments, thanks also to its 94% high efficiency which generates less heat. It can also provide up to 340W without forced air cooling.

The series comes in 24, 48 and 56 VDC standard output voltages with additional 12 and 36 VDC output voltage variants expected to follow. Samples are available for evaluation towards the end of July.

These also offer a +5 VDC stand-by output capable of 1 A. Available control signals include Power Good (P_OK), Remote On / Off (-PS_On) and Remote Sense terminals (RS+, RS-). The series can be operated over an ambient temperature range of -40 to 70 °C. Protection features include, slow blow fuses on both AC lines, input under voltage lockout (IUV), output over-current (OC), output short-circuit (SC), output over-voltage (OV) and over-temperature (OT). The series is compliant and certified to the latest IEC 62368-1 standard. Its design and construction make it compatible with UL 8750, for LED lighting applications, and IEC 60335-1 / 61558-1 safety standard for household appliances. The 94% efficient supply has been suggested as being ideal for many industrial applications, such as ATM and vending machines, LED video walls, architectural and entertainment lighting requirements.
