Key features: AK06 PS

Discover the engineering advantages that set the AK06 PS apart - and keep your operations running at peak performance.

Integrated phase-shifting autotransformer (PSA)

The AK06 PS incorporates a phase-shifting autotransformer and a multi-pulse rectifier directly within the VSD enclosure. This topological approach suppresses harmonics physically rather than filtering them out, eliminating the need for external transformers or complex cabling.

Tolerance to frequency fluctuations

The AK06 PS maintains effective harmonic suppression even when the supply frequency varies by ±5% (e.g., 47.5 - 52.5 Hz or 57-63 Hz).

±5%

Resonance-free architecture

The AK06 PS eliminates the risk of creating resonance circuits on the network side. This prevents the amplification of background harmonics often seen in weak grids.

Generator compatibility (weak grids)

The system is specifically engineered for independent networks (isolated oilfields). It performs exceptionally well with generator sets that are sensitive to capacitive loads, preventing the voltage instability often caused by standard harmonic filters.

18-pulse and 24-pulse configurations

The line offers high-order rectification options (18-pulse or 24-pulse) within the same footprint, providing a robust solution for complying with IEEE 519 standards without using active front ends or passive filters.

18-pulse, 24-pulse

NEMA 4 / NEMA 4X enclosure at +60°C

Despite housing large magnetic components (autotransformers) that typically generate significant heat, the AK06 PS is available in a fully sealed NEMA 4X cabinet rated for operation from -20°C to +60°C. This is rare for phase-shifting drives, which usually require vented enclosures or air-conditioned rooms

NEMA 4 / NEMA 4X

Compact "two-in-one" design

By integrating the PSA and the VSD into a single cabinet, it simplifies commissioning and reduces the costs associated with logistics and installing separate power connections, which is typical for traditional multi-pulse drive setups.
