DDA1-HXL - Stageline

Direkt zum Seiteninhalt


The DDA1-HXL is a DMX512 controlled 1x 2,5kW trailing-edge dimmer (reverse-phase) with respect to the replacement of old shuttle dimmers still using rising-edge technology.  It is especially designed for LED Filament light bulbs and similar lamps for ac supply but also to use with all other incandescent light bulbs, has a short-circuit protection and provides all control settings and displays on the front panel.

Due to state-of-the-art circuit technology and the use of current technology components, the total power dissipation could be reduced to 8W @ 2500W load that no cooling fan becomes necessary.

If using LED-Filament bulbs the DDA1-HXL offers a start offset and an upper offset as well as different control characteristics (curves). This allows using the whole DMX512 range of value (0-255 digit) for brightness control. The different operating states are shown by LEDs, like power is on, valid DMX512 signal, short circuit and channel active, which shines proportional to the controlled value. DMX512 start address, test mode, the offset setup as well as the dimming curves are set by three rotary code switches and a DIP switch.

Summary of characteristics:
• for LED-Filament light bulbs, light chains and ohmic light bulbs
• 2500W without cooling fan
• Brightness control between 0 to 100%, now minimum load
• electronic short circuit protection
• external control inputs for On/Off and dimming
• elevator terminals up to 2,5² wire diameter for all connections
• all setups via rotary code switches and DIP-switches
• Dimensions (customized) (LxWxH): 220 x 145 x 55 mm
• Weight: 980g
