The multimod-F-T built-in module is a thyristor-switched power factor correction module.

The thyristor-switched built-in modules are suitable for the installation of power factor correction systems in existing cabinets. The built-in modules with thyristors enable power factor correction with minimal switching delays – almost in real time. Due to their unlimited switching frequency and minimal switching delay, the thyristors switch the capacitors on and off quickly. This reduces the load on the capacitors, which in turn leads to a longer service life for the entire power factor correction system.

The convenient modular design also enables simple and flexible system expansion. All compensation modules are available choked to prevent resonance damage and thus extend the service life of the capacitors. The built-in modules are characterized by their quality and durability. We only use quality components in our handmade modules.
