welding, etc., must be completed.
Do not install the plug-in modules until all wiring installation is completed.
4.2 Ventilation of the dimmer room
The dimmer room should be dry at all times, free from dust and ventilated in such a
manner as to comply with the following:
-
Relative humidity: 5% to 90% without condensation.
-
Temperature b 5 °C and + 35 °C (ideal: + 20 °C).
In order to size the air-conditioning equipment required for the dimmer room, refer to the
following dissipations:
-
Cabinet electronics: 150 W global value for CPU(s), PSU and fans
-
Thyristor modules:
o
4 x 3 kW modules : 56 W per dimmer (worst case)
o
3 x 5 kW modules : 76 W per dimmer (worst case)
o
1 x 10 kW modules : 170 W per dimmer (worst case)
-
Sinewave modules:
o
4 x 2.5 kW modules : 60 W per dimmer (worst case)
-
No-load losses of sine wave dimmers:
o
Sine wave dimmers have a no-load loss of approximately 4 W per dimmer.
In practice, you may consider a utility factor of 0.7: that is, on the average, 70% of the
dimmers are at full load, while 30% are off.
4.2.1 Example No. 1
A dimmer room with a EURODIM Twin Tech cabinet equipped with 128 thyristors dimmers
of 3 kW and a second cabinet with 96 thyristors dimmers of 5 kW. The cabinets are fitted
with a back-up power supply for the processor unit. Utility factor = 0.7
1) Cabinet N°1:
Electronics: 1 x 150 W
Dimmers 128 x 56 W x 0.7 = 5017 W
2) Cabinet N°2:
Electronics: 1 x 150 W
Dimmers 96 x 76 W x 0.7 = 5107 W
ROOM TOTAL: 10124 W
In this example, it will be necessary to evacuate approximately 10124 W of losses.
