500W, IP66-rated rugged power supplies deliver active PFC-input

ABSOPULSE ELECTRONICS PFC 319-D4 Series of IP66-rated ac-dc power supplies with active power factor correction (PFC) are designed for heavy-duty industrial applications that require protection from the ingress of water, fog, sand, metal dust, dust, oil, insects and other contaminants.  Products are suitable for use in transportation, heavy industry, power generation and distribution, telecom, mining, marine and other severe environments. Units deliver up to 500W continuous output power, and use active power factor correction to convert a universal ac-input voltage (95V to 264Vac) to 12Vdc, 24Vdc, 48Vdc or 125Vdc. Custom input/output voltages are available on request. An optional built-in redundancy diode allows for parallel and N+1 operation.
