Gira series dimmer

Two universal dimming channels are provided for switching and dimming various light sources such as light bulbs, HV halogen, LV halogen with Gira Tronic transformers or LV halogen with conventional transformers. Both channels control different load types entirely independently of each other. Each channel can separately store a memory value as an individual activation value.

The Gira series dimmer is operated by gently pressing the corners of the button. Channel 1 is controlled on the left, channel 2 on the right. The top is for switching on and dimming up, while the bottom is for switching off and dimming down.

By pressing and holding (approx. 4 seconds) the button half way up, the currently set brightness is saved as a memory value, either on the left half for channel 1 or on the right half for channel 2.

Both dimming circuits can be synchronously dimmed up or down by pressing the central axis marked with a line, depending upon whether the upper or lower area is pressed. When the entire surface of the button is pressed and held (approx. 4 seconds), the memory value for both channels is saved.

Both outputs are always synchronously operated and both memory values stored via a connected auxiliary unit.

• Soft start for longer lamp life
• Electronic short-circuit protection
• Automatic excess-temperature protection with restart
• Asymmetric load distribution is possible, over and above the single-channel output
• Auxiliary unit operation via System 2000 auxiliary units
