ABSOPULSE Electronics has recently added two series to its line of compact, 3-phase, high input voltage ac-dc power supplies. The series is suitable for many industrial applications including factory automation, industrial machinery and equipment.
The power supplies are available in 300W or 500W output power operate directly from 3-phase inputs of 400Vac (360-440Vac), or 480Vac (430-530Vac). They deliver a single output of 24V, 48V, or 125Vdc. Custom input and output options are available on request. The units are designed to meet EN/UL60950-1 and equivalent standards. The input meets EN55022 Class A with wide margins. They operate over a 0°C to +50°C temperature range for full specification with no requirement for temperature derating. Wider temperature ranges can be accommodated on request. The 300W version is cooled by conduction and natural convection and the 500W design by three high quality internal fans.
