Indication Description Remarks
(-) OUT Analogue output (-)(Optional) configured as 4-20mA, 0-20mA or 0-10V.
Refer to section
6.6 page 21 for hardware
settings. .
Analogue output can be programmed as a
signal proportional to output power or
average of 3 phase currents or I1 or I2 or
I3 or as a reflection of the analogue input
to the TPS.
Refer to section
7.7.2 page 30 for
programming analogue output.
3.6 Input / Output indication
3.7 Load Connections
The TPS can be connect the load as shown in section
4.1 on page 12. The available configurations are:
Wye with Neutral Connected, Wye with Neutral not Connected, Delta or inside Delta.
Load connection type must be programmed to TPS. Refer to section
7.7.1 page 28.
Note:
Any number of parallel branches may be connected in the shown connection types provided that the total
connected load will not exceed the current rating of the TPS unit.
3.8 Modes of operation
3.8.1 Zero Crossing
In this mode of operation thyristor’s firing is performed so that current starts at its zero crossing point .
Main advantages of this mode are:
Minimizing RFI noise.
Minimizing current THD.Main disadvantages are:
No “Soft start”.
High inrush current in case of load with temperature dependant characteristic (lower resistance when
cold)
Current may vary in time.
In this mode of operation the TPS is programmed to operate in a cycle. (Tct)
When, during this cycle, analogue input is set to maximum – The TPS will conduct continuously.
When analogue input is lower, a proportional number of waves will be delivered to the load during Tct.
Firing method must be programmed to TPS. Refer to section
7.7.1 page 28.
