Thyristor switching module Dynaswitch-L
Ultra-fast switching solution for low voltage capacitors
Dynaswitch-L enables high-speed switching of low voltage capacitors through thyristors. Because of a fast, transient free switching, the reactive power demand can be compensated quickly and accurately. This helps ensure good power quality in networks with highly dynamic loads.
Dynaswitch-L can be operated through an automatic power factor controller, a solid-state relay or a programmable logic controller (PLC). It is also possible to trigger multiple Dynaswitch-L modules to achieve a greater reactive power compensation. Having a robust and safe design, Dynaswitch-L is easy to install, needs minimal maintenance and is compatible with capacitors with or without detuning reactors
Applications
Reactive power compensation for dynamic and fast switching loads, e.g.:
- Large welding loads / distribution boards
- Elevators and cranes
- Wind turbines
- Machines with high switching frequency, e.g. sawmills, tunnel drills etc.
