Heiland LED Control Unit for Timer

Control unit for B&W processes using an external timer.
Necessary for controlling Heiland LED for enlarger.

If you like to continue to use your existing timer or analyzer, please choose this control unit to set the color of the LED cold light source.

By rotating the left knob choose the mode:
White light for focusing purposes or to expose fixed grade paper.
Green and blue light to expose multigrade paper in the range of grade 00 to 5.
Safe red light to align the paper or to position your hands or a tool for dodging.
The intensity could be adapted to the print size in a range of 2 f-stops by means of the right hand knob.

All values are dialed in by rotary knobs with rests and are displayed by a safe red LCD in large numbers. This enables convenient operation and repeatable print results.

A high tech power supply ensures stable light output, even during main voltage fluctuations.
