DATAKOM DFC-0124 Power Factor Controller, 128x64 B&W display,144x144mm, 24steps + RS485 + SVC

* All prices are retail and VAT exclusive


The DFC-0124 is an advanced, precision 24 step power factor control and metering device offering unrivalled internet monitoring capabilities in a standard 144x144mm panel mount enclosure.
The unit has various models offering 12-18-24 step outputs. Outputs can be selected as contactor or static switch drivers in blocks of 6. Every output is capable of driving single or three phase, capacitor or reactor.
The unit is very simple to install and commission thanks to the automatic setup and connection correction features.
Vast communication capabilities are embedded to the unit. It does not require any external component.
The unit itself is a web page and can be opened through any browser for remote monitoring. The central monitoring feature can monitor thousands of meters on one screen.
Thanks to its SVC outputs it can match the exact target pf value independently of capacitor rating selections.

SVC stands for “Static Var Compensation”.
The unit has 3 SVC outputs which are duty cycle controlled PWMs that control 3 reactors with a precision of 1000 steps.
Thus the controller is able to supply almost any required reactive power on each phase, enabling matching the exact required PF, independently from capacitor bank selection.
