Compact 2 x 4in Power Supplies provide up to 300W
Powersolve just announced a series of compact, single output AC-DC power supplies designed to provide as much as 300W output. They feature a wide operating temperature range of -30⁰ to +85⁰C (with some derating). The six model PSY280 series are open baseplate units with a tiny 2 x 4in (50.8 x 101.6mm) footprint and a height of 1.31in (33.5mm).
Operating from a wide 90 to 264VAC input range with active PFC, models in the PSY280 series provide single fixed output voltages of 12V, 18V, 24V, 30V, 48V or 54V DC, providing up to 150W convection cooled, 180W conduction cooled through baseplate and 250W with fan cooling. With both conduction and forced air cooling, a PSY280 unit can give up to 300W output power. A 12V, 0.3A fan supply is a standard feature.
PSY280 units are efficient (up to 92%) and feature a no load power consumption figure of 0.15W without fan. The power supplies are protected against short circuit, over current, over voltage and over temperature.
The units have a high capacitive load capability, are suitable for Class I and Class II operation and feature an extra low leakage current figure of less than 100µA.
The PSY280 series meet all relevant EMI radiated and conducted standards and have a number of safety approvals pending. Powersolve can also supply models with any output voltages from 9V to 57VDC, still within the safety approvals, but these may be subject to minimum order quantities.
