DC/DC Converters

Unleash the power of efficient energy conversion with Powerbox's lineup of DC-DC converters. These converters play a crucial role in altering the voltage of direct current (DC), ensuring compatibility between power sources, such as a battery and load device. Ranging from 3W to 40KW, our DC-DC converters are designed to handle a wide spectrum of power requirements across industrial, railway, telecommunications, defence, power utility, and vehicle applications. 

Many models include the added benefit of isolation, designed to separate the input and output circuits, providing safety and preventing electrical interference between devices.

Powerbox offers a wide range of DC-DC converter options from leading manufacturers , available in versatile form factors including Chassis Mount, 19" rack mount, Wall Mount, Din Rail Mount, and PCB mounted configurations, ensuring flexibility for diverse installation needs. 

In addition, our team can assist with designing a suitable system that meets your unique requirements around cooling, redundancy,  monitoring and control, form factor, and electrical connections. 

If a commercial off-the-shelf (COTS) design is not available, Powerbox has the capabilities to design and manufacture a custom DC-DC converter tailored to your application requirements.
