VS-VSKDS440/030

Diodes - rectifiers - arrays are an integral component of a power system, providing protection against shorts and overvoltage conditions as well as a means for rectifying alternating current (AC) power for further use in DC applications. The VS-VSKDS440/030 is a three-phase, full-bridge, active rectifier array with SCR output stages, ideal for high-power applications such as industrial equipment, telecommunication, computing and medical systems. The device is suitable for use in single and three-phase AC power systems and provides protection against overvoltage and overcurrent conditions.

The device features an active rectifier array of three SCR pairs, driven with a precision digital controller that can either be powered off or driven by an external signal. By using this combined digital and SCR output stages, the power delivered by the device can be controlled over a wide range of ratings and frequencies from 0.2A to 200A. Additionally, the device provides the flexibility to be configured for both single and three-phase AC power systems.

In single phase AC power systems, the VVS-VSKDS440/030 is configured as a full-bridge rectifier, where both SCR pairs are activated for each phase. The SCRs respond to both positive and negative peaks of the AC waveform and transfer the positive voltage peaks to the load. By this configuration, the device can provide current to the load while allowing the negative peaks of the AC waveform to pass through the SCR pairs without being interfered with.

In three-phase AC power systems, the device is typically configured to provide a three-phase rectifier. Here, the digital controller maintains a constant average current flow to the load, while the output SCR pair is alternately activated to follow the AC waveform and thus provide a regulated DC output. The device operates in the same way for any load current rating, eliminating the need for current sensing, thereby simplifying the design and providing maximum efficiency.

The VS-VSKDS440/030 active rectifier array is also equipped with various integrated safety features, such as overvoltage protection, overcurrent protection and thermal shutdown. This ensures that the device can operate safely in any environment, while providing reliable and efficient power conversion with very low dissipation. Furthermore, the device is quite easy to install and comes with a standard 4-pin connector, making it suitable for a wide range of applications.

Overall, the VS-VSKDS440/030 is a reliable solution for rectifying three phase AC power for use in DC applications. The digital controller paired with the SCR output stages allows for reliable and efficient power conversion over a range of ratings and frequencies. The integrated safety features make it safe to use in any environment, while its simple to install, 4-pin connector make it suitable for a range of applications.
