# Products

> VectorQ2 for 208-volt and VectorQ5 for 480-volt three-phase networks. Our solid-state controllers connect in parallel at the panel.

## 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](https://3dfs.com/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.

### 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.

### Impedance matching

Source to load

The controller matches impedance between source and load continuously, 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.

[How the correction works](https://3dfs.com/technology)

- 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.
