Best for targeting system integrators working on low-voltage battery stacks, AGVs, or test stands where current handling is the main bottleneck.

High current doesn’t have to mean complex cooling. ⚑🌬️

When working with battery systems and low-voltage DC buses, the challenge is rarely just voltageβ€”it’s moving serious current without thermal runaway or bulky external plumbing.

Meet the RedPrime 40kW DC-DC Converter.

Packing up to 200Adc on the low-voltage side into a compact 28.5 kg frame, it gives power designers the current density they need with the operational simplicity of air cooling.

When expanding utility-scale energy storage, microgrids, or commercial EV charging depots, you don’t just need a converter moduleβ€”you need a complete, standalone conversion system ready for deployment.

Meet the 200kW, 850V, 400A DC-DC Cabinet from Zekalabs.

Packaged in a robust, air-cooled 600 x 600 x 1950 mm industrial cabinet, this system delivers bidirectional power conversion from 0V up to 850Vdc with zero complex liquid infrastructure required.

A microgrid is only as resilient as the power conversion backbone holding it together. ⚑🏝️

Operating independently from the main grid sounds straightforward until real-world volatility hits: solar generation spikes at midday, commercial EV chargers draw heavy transient loads, and local battery stacks need rapid cycling.

Without fast, reliable power conversion, balance quickly turns into bottleneck.

That is where Zekalabs hardware bridges the gap:

πŸ”„ DC-DC High-Voltage Converters: Connect variable renewable inputs directly to battery banks and supercapacitors across wide voltage ranges (up to 1200Vdc), operating bidirectionally to absorb surges and supply instantaneous DC bus support.

⚑ Bidirectional AC-DC Inverters: Stabilize local AC loads in real time, seamlessly alternating between charging storage assets and injecting power to handle peak demand.

πŸ“Š Intelligent Integration: With native Modbus, CAN, and Profibus protocolsβ€”alongside ZekaTraceβ„’ and ZekaStreamβ„’ diagnostic telemetryβ€”our units integrate directly into your EMS for responsive, automated load balancing.

πŸ“ˆ Maximized Efficiency: Up to >99% efficiency means minimal thermal waste, simpler cooling requirements, and lower operating costs across your entire installation.

Whether you are designing a remote industrial facility, an off-grid campus, or a resilient municipal microgrid, Zekalabs provides the modular hardware to keep your local network stable 24/7.

Strong partnerships drive global progress. 🀝🌍

At Zekalabs, we believe that true innovation cannot happen in a vacuum. To build cutting-edge power conversion technology, we must be actively engaged with the ecosystems that shape our industry and international trade.

That is why we are proud members of two influential business and engineering communities:

BASEL (Bulgarian Association of Electrical Engineering and Electronics): Since 1994, BASEL has been the cornerstone of Bulgaria's electronics sector. This membership keeps us deeply connected to regional engineering innovations, local talent, and competitive advancements.

AmCham Bulgaria (American Chamber of Commerce): Connecting over 350 multinational companies, AmCham plays a vital role in fostering international partnerships and strengthening the transatlantic business environment.

Through these memberships, we continue to exchange knowledge, drive sustainable progress, and expand our collaborative reach across continents.

When building test stands for batteries or supercapacitors, you don't need rigid hardware. You need a precision instrument. ⚑πŸ§ͺ

Testing diverse energy storage architectures means your infrastructure must adapt to extreme electrical realities. Whether you are validating next-gen flow batteries, cycling heavy-duty packs, or charging supercaps up from zero, your power conversion system dictates your testing capabilities.

Zekalabs high-voltage, high-power DC-DC converters are engineered specifically to be the flexible backbone of advanced test stand infrastructure.

Why they excel on the test bench:

πŸ”‹ Universal Storage Support: They handle all battery chemistries and supercapacitors seamlessly, thanks to their ability to support low voltages down to 10V on the DC side.

πŸ”„ Smart Energy Recycling: Moving power dynamically between battery stacks to cut electricity costs is completely achievable due to their inherent bidirectional nature.

πŸ”Œ Seamless EMS Control: Fully fluent in your network with native Modbus RTU, Modbus TCP, CAN, and Profibus control, plus additional digital/analog I/O for custom automation.
