Tronic Power Factor Controller PF CO21 with 21 Steps
TSh 966,500
Our review
The Tronic Power Factor Controller PF CO21 is a panel device for managing the power factor of an electrical installation. It offers 21 adjustable steps, so it can switch capacitor banks in finer increments than controllers with fewer outputs. That makes it most relevant to facility managers, electrical contractors and plant engineers running loads where power factor correction is already part of the design. Before buying, confirm your capacitor bank's step configuration and whether 21 outputs match it, since a controller with too few or too many steps limits how smoothly correction is applied. Also check the control voltage and current transformer input your system uses, as these details are not listed here. Compared with basic controllers, the higher step count suits larger or more variable loads; smaller installations may find a simpler unit sufficient. It is available on Sokonia.
