DC-DC Converters

DC-DC converters are essential components used in various applications to convert a direct current (DC) voltage from one level to another. They play a critical role in ensuring efficient power management across different electronic devices and systems. DC-to-DC voltage converters come in isolated and non-isolated varieties, each serving specific purposes depending on the application's safety and efficiency requirements.

Isolated DC-DC converters convert a source of direct current (DC) from one voltage to another and contain an electrical barrier between the input and output to improve safety.

Non-isolated DC-DC converters, on the other hand, do not have an electrical separation between input and output. They are typically used in low-power applications where efficiency and compact size are critical.

RS New Zealand offers a comprehensive selection of high-quality Converters from industry-leading brands, including TDK-Lambda, XP Power, Murata Power Solutions, Recom, and many more. Whether you need a 12V-to-12V DC-DC converter, a DC-to-DC regulator, or a DC-to-DC converter module, RS NZ has the right solution for your needs.

What are They Used For?

Isolated DC-DC converters are used within equipment and devices containing different circuits or sub-circuits where it is necessary to convert the voltage of a DC supply from one level to another. An example would be a device with various circuits, some needing 12 volts (V) and others needing 5V. An isolated 12v DC-DC converter could be used to buck the 12V input to a stable 5V for the lower voltage circuits.

On the other hand, non-isolated DC-DC converters are suitable when isolation between the input and output circuits isn't critical. They are often more compact and cost-effective due to the lack of isolation components. For converting AC to DC, an AC-DC converter would be used.

Types of Isolated DC-DC Voltage Converters

Isolated DC-DC converters come in a wide range of input and output voltages in both single outputs and dual outputs. At RS NZ, we also offer medical, railway and site-approved converters for safety-critical applications.

Single Output Converters

Single-output DC converters are ideal for applications requiring a single, regulated voltage level. They provide a clean and stable power source for various electronic circuits.

Dual Output Converters

Dual output isolated DC-DC converters offer the versatility of generating two independent, regulated voltage levels from a single input source. This eliminates the need for multiple converters, simplifying your design and saving space.

Medical Approved Converters

For applications in the medical field, safety is paramount. Our medical-grade isolated DC-DC converters comply with rigorous medical safety standards, ensuring reliable and dependable power delivery for critical medical equipment.

Railway Approved Converters

The railway industry has specific requirements for power electronics. Our railway-approved DC-DC isolators meet stringent railway standards for shock, vibration, and temperature extremes, ensuring reliable operation in harsh railway environments.

High Power Density Converters

For applications requiring high power output in a compact space, high-power density DC-DC converters with isolation are the perfect solution. They deliver superior efficiency and minimise footprint, ideal for space-constrained environments.

Low Power Converters

Low power isolated DC-DC converters are perfect for applications where minimising power consumption and size is critical. They offer efficient power conversion for low-power devices while maintaining isolation benefits.
