Polyamp Introduces the PM500, a New DC / DC Family of Converters

500W converter

PM500 is a new generation of 500W convection cooled AC / DC converters. They are freestanding units that can be mounted on walls, chassis, and DIN-rails. The units fits into 19in rack mounting 2U, and can be stacked with optional panels as 2 pluggable units, or as 5 units with a 6U panel.

The PM500 features inputs of 110Vd.c. and 220Vd.c., with outputs of 13.2V – 110V, and very low noise input and output. Optional 24V and 48V outputs meet the EN55022 level B.

Wide input voltage ranges to meet railway or vehicle requirements are available.

Features include:

  • Only 2U including convection cooling
  • Pluggable in 19in rack format: 2U with 2 units, and 6U with 5 units
  • Convection cooled -25 to 70°C
  • Two outputs: before and after series diode
  • Over and undervoltage alarm
  • Overvoltage protected outputs
  • Over temperature limit

Optional features include:

  • 70°C convection-cooled at known load
  • Input voltage range according to railway standard EN50155 / IEC60571
  • Modification for minimum fire load according to railway standard EN 45545
  • EN / IEC 6100-4-5 level 4, thus ± 2kV / ± 4kV (2 / 12 Ohms)
  • Panels for 19in mounting 2U and 6U
  • DIN TS 35 mounting

The PM500 series meets the low emission requirements of light Industry and telecom standard EN / IEC 61000-6-3. As a special option, Telecom Requirements standard EN55022 level B can be met on output.

The series meets heavy industry immunity levels according to EN / IEC 61000-6-2. However, it can also meet tougher levels used in sub-station, railway and power utilities.

The converter meets generic immunity levels according to EN / IEC 61000-6-1 and 6-2, and emission levels according to EN / IEC 61000-6-3, which means it can be installed in all environments defined in the EMC directive.

The product fulfils requirements for electric safety standard EN / IEC 60950 , as well as RoHS directive 2011/65 / EC.
