DCTL thyristor modules

LOVATO Electric completes its range of power factor controllers with the new thyristor modules DCTL series.


The DCTL series is available in 3 variants for nominal operating voltages from 400VAC to 690VAC and for power steps from 7.5 to 120Kvar.

They are characterized by the noiseless operation and the switching to zero crossing, which ensures very fast switching times and minimizes current peaks on capacitors.
Thanks to the presence of integrated current transformers, it is possible to protect the bank of capacitors and monitor measures such as the residual power of the bank of capacitors, voltages, currents, temperature of the heat sink and capacitors, THDI, working hours, etc..

The DCTL series feature a default programming that allows immediate use without the need for any programming.
If necessary, however, it is possible to modify the parameters, such as the configuration of the protection thresholds or the rated values to adapt them to each application via App or software via NFC connectivity or frontal optical port.

These new products integrate a programmable relay output for global alarm signalling or external fan control, as well as one or two cooling fans monitored by the control logic as standard to ensure proper ventilation.

The DCTL control can be done by the DCRG8F controller via static outputs or via RS485 BUS via optional card.
This last type of connection allows to see on the display of the DCRG8F controller the status and measures of each DCTL thyristor module.

Sizes up to 60Kvar are equipped with power terminals with double screw terminals and can be fixed on DIN rail with optional accessory.
The installation can be done either vertically or horizontally without any downsizing.
