Fader Controls

ENV-226
Stimulus Light Fader Control

A precision screwdriver adjustable control and power regulator circuit provide a "second" stimulus of reduced intensity when used with the stimulus light (ENV-221). The ENV-226 requires two separate outputs to activate a full or reduced intensity stimulus. This unit may also be used with the house light (ENV-215M) or stimulus/house light (ENV-227M).

ENV-226A
Four Level Fader Control

This unit is similar to the ENV-226 except it has four levels of light control instead of two. Each level is user adjustable and requires a separate output control.

ENV-226B
Three Channel Light Control

This unit consists of three independent light intensity dial controls that allow you to record and repeat settings precisely. Connect each to one or two stimulus lamps with a current rating up to 170 mA at 28 V DC. When used to counter balance natural preferences in multiple compartment chambers, this device can be connected directly to a power supply. When used with stimulus lights, or whenever computer control is required, each channel may be connected to a separate 28 V DC output.
