Thyristor modules enable power factor correction caps

Epcos AG expanded its TSM series of thyristor modules to include the TSM-HV50 and TSM-LC200 types. These new thyristors enable power factor correction (PFC) capacitors, including PhaseCap, PhaseCap HD, WindCap, PhiCap and MKV capacitors, to be switched silently and without wear, for a longer life. In addition, there is no feedback to the grid in the form of transients.

The TSM-HV50 is designed especially for industrial networks rated at 690V and for capacitive loads of up to 50kvar. The TSM-LC200 power thyristor module was designed for the voltage range of 380V or 400V, and is able to switch capacitive loads of up to 200kvar. The switching times of both modules are in the region of 5ms. These modules feature an automatic function for monitoring voltage, phase and temperature. Status indication is via LEDs.
