DC/DC converter: universally applicable for all applications

Maximum security of supply and minimum downtime characterize a good power supply system. However, the increasing complexity of supply solutions and the increased use of battery backup systems may adversely affect the stability of the DC control voltage. Supply disruptions such as voltage fluctuations due to different potentials or voltage drops due to long lines may result.

Our product range in the field of DC/DC converters

Stay competitive with the benefits of our DC/DC converters. We can offer a wide range of solutions to meet your expectations in terms of space, reliability, durability and digital integration in control systems, along with Industrial IoT capabilities (enabler value to be released from your data). Our robust power converters are suitable for almost every application in both domestic and international contexts. You can also find the perfect DC/DC converter in the large selection of our online product catalogue.

PROtop DC/DC converter – “the communicative”

The integrated ORing MOSFET serves for reliable decoupling of possible internal short circuits. It allows direct parallel connection of ACDC and DCDC converters of the PROtop series for redundancy purposes or to increase performance. The use of the usual diode or redundancy modules becomes obsolete. In addition, PROtop DCDC converters feature the powerful DCL technology – and your communication module allows full data transparency and remote control.

  • High dynamic range thanks to unique DCL technology
  • Communication modules for condition monitoring
  • Direct parallel connection by means of integrated ORing MOSFETs
  • International approvals (cULus, DNV, RMC/ACMA, TÜV)


With galvanic isolation and protection class III for groundless systems, the PRO DCDC converters are particularly suitable for use in independent supply systems. The space-saving module can optimally convert voltage levels, offers above-average power performance, comprehensive safety functions, and a high efficiency of up to 95 %.

  • Outstanding peak load reserves thanks to DCL technology
  • High efficiency up to 95%
  • -25 bis +70°C wide operating temperature range (Start-Up at -40°C)
  • International approvals (cULus, cULus Class I, Div. 2, ATEX, IECEx)

Further product families and accessories for DC/DC converters

Optimize your power supply with accessories from our Weidmüller product range. For example, with a redundant power supply using our modules, you can protect your DC/DC converters and switching power supplies from failure of the 24 VDC control voltage. We have the right product for every requirement and can also help you identify the right solution for your needs.

Redundancy and diode modules for DC/DC converters

The benefits of establishing a redundant supply are twofold: neither the failure of a switch mode power supply nor that of an individual phase will cause the 24 V DC control voltage to fail. Each redundant branch is capable of supplying the full output load separately.
