Responding to the growing demand for high power, conduction-cooled power supplies, Powersolve has introduced the PSL400BP Series of baseplate cooled AC/DC units. The new power supplies are designed to offer single outputs of 5V, 12V, 24V or 48V DC with output power up to 400W.

The input range is wide at 85 to 264VAC, 47 to 63Hz and all models feature active Power Factor Correction to conform with EN61000-3-2.

These ruggedised power supplies are housed in a robust extruded aluminium chassis designed for use in industrial or other types of equipment where cooling fans are undesirable and convection airflow is not available. Units can be mounted in a sealed box providing that the external heat sinking is adequate to maintain the baseplate at a temperature of 80º C or below.

Standard features include over current and short circuit protection, over voltage and over temperature protection, output voltage adjust, remote on/off, output power good signal, +5V 1A standby output and LED indicator to show Vout present.

All units are also designed to be able to operate in parallel for N+1 redundant operation and feature integral ORing diodes.

The PCB is conformally coated for protection against the ingress of moisture and dirt and operating temperature range is -20 to +70º C, providing the baseplate temperature can be maintained at 80ºC or below. All power supplies will carry full safety approvals (pending) and conform to EN55022’B’ conducted EMC requirements.
