Connection
Connect this module according to the connection diagram:
Connect a 12V DC power supply to the – 12 + connections. Respect the polarity! When polarity is reversed, the fuse will
blow.
Up to 10 loads can be connected to the outputs. These can be small lamps, relays or cold-cathode fluorescent lamps. The
current in each separate channel cannot surpass 400mA. Respect the polarity!
When a correct power supply is connected, LED LD1 will light up. All 10 red LEDs will already display a light effect .
Be careful when connecting the cold cathode fluorescent lamps: the 'FLPS1' power supply module generates a
life-threatening voltage over the lamp connectors, which may cause electroshocks.
Settings:
Before switching on the module, set the jumper to indicate how many lamps are connected.
For example : to make a 4-channel running light, set the jumper to '4 CH'.
If the module is powered on without the jumper, the 10 channels will flash simultaneously ; this way the module can be used
as a 10-channel flashing light with adjustable speed.
