NOVAR 2600 Operating Manual
2.2.3.1 Relay Outputs
Any combination of compensation capacitors or chokes (three-phase, two-phase or single -phase) can
be connected to the instrument outputs via appropriate contactors.
Fig. 2.2: Output connection, various types of capacitors
If not of all outputs used, you can use upper three relay outputs for alarm signalling or for
heating/cooling control ( see example wirings further below).
2.2.3.2 Transistor Outputs
The “T”-models are equipped with up to 18 MOSFET-type transistor outputs.
These outputs are designed to connect to thyristor switches’ input otpocouplers via limiting resistors.
This is reflected in limit parameters of the transistor outputs as well (see technical specifications).
Voltage of magnitude usual for relay outputs connection is forbidden !!!
Otherwise, the instrument can be damaged !!!
Respect maximum voltage and current rating - see technical specifications.
The transistor outputs must be powered from the switching module’s power supply or from an external
power supply giving about 24 V DC and protected with a 1 A. It is recommended to connect negative
pole of the supply to the common terminals
C1 , C2 ( No.15 and 25 ), but the polarity is free generally.
Any combination of compensation capacitors or chokes (three-phase, two-phase or single -phase) can
be connected to the instrument outputs via appropriate switching modules. If not of all outputs used,
you can use upper three outputs for alarm signalling or for heating/cooling control ( due to the nature
of outputs commonly via an auxiliary relay).
2.2.4 Digital Input
The models with 7 or 16 outputs are equipped with the digital input. It can be used for the 2 nd tariff
control of power factor control process, for time synchronization or for electricity meter tariff control.
