Compact single output power supplies provide up to 300W

Powersolve has announced a new series of compact, single output AC/DC power supplies designed to offer as much as 300W output. They have a broad operating temperature range of -30C to +85C (with some derating). The six model PSY280 series are open baseplate units with a tiny 2" x 4" (50.8mm x 101.6mm) footprint and a height of 1.31" (33.5mm). Operating from a wide 90VAC to 264VAC input range with active PFC, models in the series give single fixed output voltages of 12V, 18V, 24V, 30V, 48V or 54VDC, offering up to 150W convection cooled, 180W conduction cooled through baseplate and 250W with fan cooling. With both conduction and forced air cooling, a unit can provide up to 300W output power. A 12V, 0.3A fan supply is a standard feature. The units are efficient (up to 92%) and offer a no-load power consumption figure of 0.15W without a fan. The power supplies are shielded against short circuit, over current, over voltage and over temperature. The units have a high capacitive load capability, are ideal for Class I and Class II operation and offer an extra low leakage current figure of less than 100µA.
