IP66-rated AC-DC power supplies are designed for heavy-duty industrial applications that require protection from the ingress of water, fog, sand, metal dust, dust, oil, insects & other contaminants.

Introducing the new PFC 319-D4 Series of heavy-duty, IP66-rated AC-DC power supplies with active power factor correction (PFC).

The  power supplies are designed for heavy-duty  industrial applications that require protection from the ingress of water from powerful jets, fog, sand, metal dust, dust, oil, insects and other contaminants.  They are suitable for operation in transportation, heavy industry, power generation and distribution, telecom, mining, marine and other severe environments.

The PFC 319-D4 power supplies deliver up to 500W continuous output power. They use active power factor correction to convert a universal ac-input (95V to 264Vac) to 12Vdc, 24Vdc, 48Vdc or 125Vdc. Custom input/output voltages are readily available. An optional built-in redundancy diode allows for parallel and N+1 operation.

Each PFC 319-D4 power supply is enclosed in a robust die cast aluminium D4 size IP66-rated package.  The input and output have sealed cable glands, circular connectors or custom connections. Application-specific vents for pressure equalization ensure that pressure inside the enclosures is equalized, that the strain on connectors is minimized and the environmental seal remains impermeable. The D4 packages measure 230 x 113 x 448 mm (H x W x D) – these dimensions include mounting flanges and base plate.

The 500W power supplies are cooled by internal conduction to the walls of the IP66-rated enclosure and by base plate to an external chassis or cabinet wall. Additional convection occurs through the outside surface. If installed on a heat-sinking surface, cooling is further enhanced. The power supplies are rated for operation over a -25ºC to 50ºC temperature range for full specification. Wider temperature ranges are available as an option. The internal boards are ruggedized and conformal coated for immunity to high levels of shock and vibration.

The PFC 319-D4 power supplies comply with the EN61000-3-2 directive for low input harmonic distortion. The power factor is better than 0.97 at full load for the entire input range.  The units also comply with EN/UL60950-1 and equivalent UL and CSA international safety standards. Filtering on the input and output contributes to low output ripple and noise. The input meets EN55032 Class A with wide margins; Class B is available on request.  Comprehensive electronic protection includes 4300Vdc input-output isolation, inrush current limiting, rectangular current limiting with short-circuit protection on the output, thermal self-resetting shutdown and output over-voltage protection by double regulator loop completely stable and independent of main loop.

We offer a broad range of DC- and AC-output power supply solutions with IP66-rated protection. They are available in output power ratings from 30W to over 1kVA. For further information on these designs, please refer to this IP66-rated power solutions page.
