300W Watertight, IP66-rated AC-DC (or DC-DC) power converters offer wide input ranges

Designed and built with full IP66 protection for operation in severe environments.

The series accepts either AC- or DC- inputs with wide input ranges. These include 115Vac (95–132Vac), 230Vac (190–264Vac), 250Vdc (210–290Vdc), 300Vdc (250–350Vdc) or custom. They deliver 300W continuous output power. Output voltages include 12Vdc, 24Vdc, 48Vdc, 125Vdc or custom. Efficiency is load dependent, typically 80% at full load. An optional built-in redundancy diode allows for parallel and N+1 operation.

The HBC65-D3-IP66/67 power supplies are packaged in a rugged diecast aluminum IP66 enclosure with sealed circular connectors, cable glands or MIL. They are also are protected from water, humidity, dust, sand, oil, salt, fog and insects. The internal power supply unit is fully ruggedized for increased immunity to high levels of shock and vibration, and the internal boards are conformal coated.

Cooling is by internal conduction to the walls of the IP66 enclosure and by surface convection which ensures operation within a -25°C to +55°C temperature range for full specification. If installed on a heat-sinking surface, higher output power is possible.

Comprehensive electronic protection includes heavy filtering on the input and output, 4300Vdc input-output isolation, inrush current limiting, reverse polarity protection and over-voltage protection by a second regulator loop. The units comply with EN60950-1 and corresponding UL and CSA international safety standards.
