POWER SUPPLIES with LOW-VOLTAGE INPUTS

These fixed or adjustable, non-isolated single-output power supplies/converters are required for connecting to a transformer secondary. Maximum current output ranges from 0.8A up to 20A depending on the model.
All the ranges are designed for industrial use, DIN Rail Mountable and have IP20 protection rating, as well as guaranteeing high performance and reliability, even in the most difficult environments. All products comply with low voltage directive 93/68-EEC.

SW Non-isolated AC/DC and DC/DC Converters

Main features:

  • Input rated voltage: 24 Vac, 24 Vdc, 48 Vdc
  • Output: 5 - 12 - 24 Vdc
  • Output In: 3 - 5 - 7 A
  • Non-adjustable output
  • Extremely compact dimensions
  • Ambient temperature operation field: 0 - 50° C
The SW range comprises single-output power supply units with an excellent price-performance ratio. Very small in size, these power supplies are 90% efficient. All models have short circuit and overload protection. They do not require any form of regulation.

PFAL Non-isolated AC/DC and DC/DC Converters


Main features:

  • Input rated voltage: 24 Vac, 24 Vdc, 48 Vdc
  • Output: 5 - 12 - 24 Vdc
  • Output In: 0,8 ÷ 20 A
  • Adjustable output ± 10% ±90%
  • Extremely compact dimensions
  • Ambient temperature operation field: 0 - 50° C
The PFAL range of single-output power supply units control output currents up to 20A and can guarantee stable output voltage. The entire range, designed for connection to a transformer secondary, enables both serial and parallel connections to be made. They are housed in metal cases, are DIN Rail Mountable and have short-circuit and overload protection and adjustable output.
