AL4400
PWM Dimmer Controller
The AL4400 provides all the control features required for a high
specification DC - PWM dimmer.
Applications include low voltage lamp dimming, LED, LEP, EL and cold
cathode colour mixing.
The AL4400 is the core technology used in the Power-Pipe and
Colour-Fill.
AL4800
PWM Moving Lamp Controller
The AL4800 provides all the control features required for a medium
specification moving lamp or moving yoke.
The basic configuration provides micro-stepping (high resolution)
outputs for pan and tilt. Pin inputs allow 2 settings for pan motor
type and 4 settings for tilt motor type.
The colour wheel and gobo wheel motors are also micro-stepping
motors and assumed to be continuously rotating with inputs for a
home sensor.
The iris motor is also a wave drive stepper motor channel with end
stop sensor.
Applications include moving lamps, moving yokes, colour wheels and
general purpose animatronics.
Custom variations of this part can be produced subject to order
quantity.
