SDE Products
When power quality degrades, a network wastes energy, makes excess heat, wears equipment early and loses capacity. VectorQ controllers correct it at the panel.
- Solid state. Digital, full bridge per phase. Each phase has its own full bridge. The switching frequency is adaptive and controlled by a digital signal processor.
- In parallel. At the panel. The controller connects alongside the panel, not in the power path. Power stays on during installation.
- No setup. Autonomous from first power-on. Commissioning needs no laptop, no software and no configuration.
- Efficient. At least 96%, at any load. Round-trip efficiency stays at or above 96% on both models, whatever the load. That is the floor, not the peak.
The VectorQ series of power controllers

Early access
Partners can work with us beyond the models above.
- VectorQ12. Early access. VectorQ12 is available to early-access partners. Specifications are on request.
- Calibri Data Acquisition. Research and production tool. Calibri converts analog signals to digital data, stores it and runs real-time signal processing such as filtering and noise reduction.
- Labs. Research and joint development. Labs is where we work with outside teams on research, integration and joint development around Software-Defined Electricity.
What one controller corrects
Power factor
±90° to unity
The controller corrects power factor to unity. Its range is ±90°, capacitive and inductive. A low power factor makes the wires carry current that does no work, so they run hotter and leave less capacity for the load.
Harmonics
23rd order
A passive filter targets one harmonic order. Dynamic, active correction adjusts as the network changes: the controller measures through the 53rd order and corrects through the 23rd. It holds total harmonic distortion (THD) under 5% on all phases, in real time. The distortion is gone, not masked.
Phase balance
Within 20%
The controller balances the load on each phase to within 20% of the average. Neutral current falls to near zero. Unbalanced phases send current down the neutral, and an overloaded or broken neutral is a recognized cause of electrical fires and shock.
Impedance matching
Source to load
The controller matches impedance between source and load across the full operating range. It runs with the other three corrections in one automatic operation.
The pilot program
Buying a VectorQ controller starts with a pilot, not a cart.
We help set up the pilot.
- Baseline. Before the controller. The pilot opens with a baseline at the panel, before the controller goes in.
- Cycling. Controller on and off. Next, the controller cycles on and off in turns. The instruments record the whole time.
- Result. Set against the baseline. The pilot closes on an instrumented result, good or bad. That result names who measured it.
