1. Dimmer Room
1.1 Preparation
- Determine the dimensions of the dimmer room so as to place all EURODIM TWIN
cabinets easily. Provide for an open space of approximately 90 cm in front of the
cabinets to facilitate maintenance. Verify that the room access doors are large
enough to permit passage of the equipment. The cabinets can be placed against a
wall or back to back. The supply cables and the load cables can enter the wiring
compartment either from the top or bottom of the cabinet. See drawing for size and
location of cable entries.
- Provide for a free space, minimum 30 cm above the EURODIM TWIN so as to
facilitate the exhaust airflow. The dimensions and weight of the cabinets are
included
in the Chapter “Characteristics”.
-
Plan for fire extinguishers in compliance with local regulations.
-
The lighting of the area should be sufficient for maintenance and inspection. A level
of 300 lux is considered satisfactory.
-
Plan for mains outlets in the room, independent of the supply of the dimmers.
-
Plan for an Ethernet network to the control room and a cable for remote “CPU1 -
CPU2” selection (if applicable).
1.2 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 80% 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 including 150 W global value for CPU(s), PSU and fans
- Thyristor modules:
4 x 3 kW modules: 37 W per dimmer (worst case)
3 x 5 kW modules: 69 W per dimmer (worst case)
1 x 10 kW modules: 170 W per dimmer (worst case)
In practice, you may consider an utility factor of 0.6: that is, on the average, 60% of the
dimmers are at full load, while 40% are off.
1.2.1 Example
A dimmer room with a EURODIM TWIN TECH cabinet equipped with 128 thyristor
dimmers of 3 kW and a second cabinet with 96 thyristor dimmers of 5 kW. The cabinets
are fitted with a back-up power supply for the processor unit. Utility factor = 0.6
Cabinet N°1
Electronics: 1 x 150 W
Dimmers 128 x 37 W x 0.6 = 2841 W
