DC load bank
Reliable DC power and testing solutions
Test your direct current systems with precision and confidence. A DC load bank, also known as a DC test load or direct current load, is a device designed to safely draw and control current from a DC source such as batteries, fuel cells, or solar panels. This allows you to verify how your DC energy solution performs under different load conditions.
Our DC load banks are robust, accurate, and versatile, enabling you to set and measure DC voltage, current, and power with exceptional precision. Built-in safety features prevent overvoltage, overcurrent, and overheating, ensuring every DC solution you test is both reliable and efficient.
Precision measurement and flexible test modes
Each DC load bank offers voltage and current measurement accuracy within ±0.2% and resolution down to 0.001. Standard operation is in constant power (CP) mode, with options for constant current (CC), constant voltage (CV), and constant resistance (CR). This flexibility makes them perfect for a wide variety of DC energy solutions, from research and development to field testing.
DC load banks up to 1500 V
Our standard DC load banks operate safely up to 1000 V, with bespoke designs available for up to 1500 V to meet specialist requirements. Delivering continuous power up to 1000 kW, and short-term peaks beyond, they are ideal for testing high-performance DC system solutions across industrial, marine, and renewable sectors.
For large-scale testing, multiple units can be connected in parallel, providing a flexible and scalable DC power solution for complex applications.
Customised DC load bank
Safe, air-cooled and built to last
Safety is always a priority. Our DC load banks include protection against overvoltage, overcurrent, and excessive temperature, plus airflow monitoring and an emergency stop system. The air-cooled design allows for efficient heat management, and the modular build enables expansion or parallel operation for higher loads. Special configurations are available for military, offshore, and other demanding environments.
Ukana Power Solutions provides high-quality, Dutch-engineered DC load bank solutions, designed by experts, delivered quickly, and tailored precisely to your testing needs. Don’t hesitate to call or mail us for all your DC solution questions.
Advantage connectivity and remote monitoring
Integration is effortless: all units support Modbus via RS485 or TCP as standard, with other communication protocols available on request. Remote control and monitoring are simple through Modbus, and custom test profiles can be uploaded via dedicated software. Battery and fuel cell profiles can be simulated with an accuracy of ±5% in DC current and voltage, ideal for sophisticated DC power solutions.
Flexible deployment, rental and service options
Our DC load banks are available as standard IP44-protected units, in containerised formats, or as mobile units for temporary installations. Standard delivery is often from stock, with a maximum lead time of 12 weeks.
For short-term testing or temporary projects, we offer DC load bank rental, a cost-effective way to access high-quality equipment without long-term commitment. Each unit is serviced and calibrated for consistent, reliable performance throughout its lifetime (typically around five years). Tailored service contracts are also available.

FAQ DC load bank
-
What is a DC load bank and what is it used for?
A DC load bank is a device that draws controlled current from a direct current source to test how the source performs under various loads, such as batteries, solar panels, or fuel cells.
-
What is the difference between a DC load bank and an AC load bank?
A DC load bank tests direct current (DC) systems, while an AC load bank tests alternating current (AC) systems. Both types of load banks are designed for different kinds of current and applications.
-
Can I connect multiple DC load banks in parallel for higher power?
Yes, many DC load banks can be connected in parallel to achieve higher power and test larger DC power sources. Feel free to contact us for more information.
-
How do I choose the right load bank for my DC system?
Choose a load bank based on your system’s maximum DC voltage, current, and power, the desired test modes (CC, CV, CP, CR), and any specific safety or connectivity requirements. Feel free to consult our experts for advice.
