DFC-0108 is a high technology controller 
allowing the power factor of the installation to 
be stabilized to the requested value by 
switching capacitor banks through contactors. 
The unit allows also the visualization of 
various AC parameters like a network 
analyzer. 

The unit makes harmonic analysis up to the 
31th component. The THD values of all 
voltages and currents are available. 

Stepping algorithms are selectable between 
various types. Thanks to the automatic setup 
function, the commissioning and programming 
are made easy. 

 

* Electrical equipment should be installed only 
by qualified specialist. No responsibility is 
assured by the manufacturer or any of its 
subsidiaries for any consequences resulting 
from the non-compliance to these instructions. 

* Check the unit for cracks and damages due 
to transportation. Do not install damaged 
equipment. 

* Do not open the unit. There is no 
serviceable parts inside. 

* Fuses of fast type (FF) with a maximum 
rating of 6A must be connected to phase 
voltage inputs, in close proximity of the unit. 

* Disconnect all power before working on 
equipment. 

* When the unit is connected to the network 
do not touch terminals. 

* Short circuit terminals of unused current 
transformers. 

* Any electrical parameter applied to the 
device must be in the range specified in the 
user manual. 

* Do not try to clean the device with solvent or 
the like. Only clean with a dry cloth. 

* Verify correct terminal connections before 
applying power. 

* Only for front panel mounting. 

 

 

 

 

Before installation: 

 Read the user manual carefully, determine 

the correct connection diagram. 

 Remove all connectors and mounting 

brackets from the unit, then pass the unit 
through the mounting opening. 

 Put mounting brackets and tighten. Do not 

tighten too much, this can brake the 
enclosure.  

 Make electrical connections with plugs 

removed from sockets, then place plugs to 
their sockets.

 

 Be sure that relay outputs are not 

overloaded. If necessary use extra 
contactors.

 

Below conditions may damage the device: 

 Incorrect connections. 

 Incorrect power supply voltage. 

 Voltage at measuring terminals beyond 

specified range. 

 Current at measuring terminals beyond 

specified range. 

 Overload or short circuit at relay output 

 

Below conditions may cause abnormal 
operation: 

 Power supply voltage below minimum 

acceptable level. 

 Power supply frequency out of specified 

limits 

 Current transformers not matching related 

phases. 

 Current transformer polarity incorrect. 

 Inadequate on-delay setting 

 Inadequate off-delay setting
