18.1 CF Modules
CF series instruments are optional modules that if connected to the main control systems allow the adjustment of fans
with current from 2 A to 10 A.
They have an “open board” form and are available in several models:
• CF-REL for simple ON/OFF control;
• CF-05 to control through phase cut in a maximum power of 500 W;
• CF-15 to control through phase cut in a maximum power of 1.500 W;
• CF-22 to control through phase cut in a maximum power of 2.200 W.
18.1.1 CF modules: technical data
Power supply voltage: 230V~.
type of current on charge:
• CF-05: 500 W maximum.
• CF-15: 1500 W maximum.
• CF-22: 2200 W maximum.
Maximum absorption current:
• CF-05: 2,5 A maximum current at 230 V~.
• CF-15: 8 A maximum current at 230 V~.
• CF-22: 12 A maximum current at 230 V~.
Values and fuse type:
• CF-05: 5x20 2,5 A delayed.
• CF-15: 5x20 8 A delayed.
• CF-22: 5x20 12 A delayed.
the fuse considered is related to the maximum charge hypothesis (it is the fuse supplied). It is designed to protect the fan
module power component. In no case a fuse of a superior capacity must be assembled. However, the fuse value has to be
dimensioned on the charge to be piloted through the fan module (the resulting value must be lower than the maximum
value). If dimensioned appropriately it also protects the charge.
• Supplied power: varying according to the model (500W/1500W/2200W).
• Control signal type: pulse modulation.
• Protection coefficient: IP00 (open board).
18.1.2 CF modules: connections
CF modules connection is performed by using Fast-on connectors assembled on boards.
Below a list of the connection diagrams for every type of module is shown:
