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

In addition to the above, the technology can also provide up to 340W without forced air cooling. Plus, the series comes in 24, 48 and 56VDC standard output voltages with additional 12 and 36VDC output voltage variants expected to follow. Samples are available for evaluation towards the end of July 2022.

These also offer a +5VDC stand-by output capable of 1A. 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.
