Powersolve has introduced a power supply capable of providing 400W without the need for forced cooling. The PSL400BP Series of baseplate-cooled ac/dc units offer single outputs of 5V, 12V, 24V or 48V dc and will interest those designers who need high power but cannot use fans or who need to seal the power supply in a closed enclosure.
The input range is wide at 85 to 264Vac, 47 to 63Hz and all models feature active power factor correction to EN61000-3-2.
The units are housed in a robust extruded aluminium chassis and the PCB is conformally coated for protection against the ingress of moisture and dirt. Operating temperature range is -20 to +70º C, providing the baseplate temperature can be maintained at 80ºC 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 can operate in parallel for N+1 redundant operation and feature integral ORing diodes. They feature full UL, cUL & TUV EN60950 safety approvals and conformance to EN55022 conducted EMC requirements.
