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.
