In the rapidly evolving world of power electronics and renewable energy, the margin for error is zero. Testing inverters requires more than just checking if they turn on. You need to simulate real-world grid conditions, handle uneven loads, and stress-test reactive power capabilities.
Standard off-the-shelf load banks often fall short of these demands. That is why Ukana engineered a custom solution that stands unique in the market: a 100kW resistive load bank designed specifically for advanced inverter testing. Are you interested? Let’s connect!
Full control of kW, kvar and power factor
What sets this unit apart is its advanced capability to handle both real power (kW) and reactive power (kvar). Unlike standard resistive banks, our custom build allows you to increase and decrease the Cosphi dynamically.
By integrating inductive and capacitive elements, this unit lets you simulate the complex power factors found in actual industrial grids. Whether you are testing the inverter’s power factor correction (PFC) algorithms or its stability under varying load types, this machine provides the granular control you need.
Simulate phase inequality
In a perfect world, grids are balanced. In the real world, they rarely are. A critical feature of this loadbank is the ability to set the load per phase.
Based on the intuitive HMI layout, operators can independently adjust the sliders for L1, L2, and L3, as well as a combined L1,2,3 control. This allows you to:
- Test phase imbalance tolerance.
- Simulate uneven loading scenarios.
- Verify the inverter’s ability to maintain a stable output when one phase is under heavy stress and others are not.
Intuitive HMI and real-time data
We believe complex testing shouldn’t require a complex interface. The unit features a crystal-clear HMI display designed for ease of use. As seen in the interface layout, operators have instant access to:
- Slider Controls: Easy-to-grip sliders ranging from -50 to +50 for precise KW and kvar adjustment.
- Safety Controls: One-touch critical functions like “Accept resistive slider load” and the emergency “Shed ALL load” button for immediate safety shutdowns.
- Comprehensive Measurements: A dedicated “Measurements” area provides real-time visibility into Voltage (displaying specific values like 237.7V and 410.7V), COSY (Cos Phi), KVA, KW, and Amperage (A).
In modern test benches, automation is key. This 100 kw load bank is built for easy control via ModBUS communication. This allows you to integrate the unit into automated test sequences, log data remotely, and control the load parameters programmatically without even touching the screen.
100 Kw load bank: Unique in the market
There are plenty of loadbanks that can heat up resistors. However, finding a compact, 100kW unit that combines per-phase resistive loading, dynamic reactive power (Cosphi) adjustment, and advanced ModBUS integration in a single custom package is rare.
This is not just a tool, it is a comprehensive testing platform built to push your inverters to their limits and ensure they are ready for the grid.
