Doug Fleenor Design 125EE DMX Enhanced Isolation Amplifier and Splitter, 1-Input, 5-Outputs

The Enhanced2 Isolated Splitter [125EE] includes all the features of DFD's standard models with added protection to meet the needs of harsh operating conditions. As with their standard splitters, all outputs are isolated from the input and from the other outputs by optical couplers. Every output has its own power supply and line driver. For protection against electrical storms, the 125EE adds four transient absorbers on the input, two on each output, and one on the power line. To protect against miswiring, it also has self resetting fuses on the DMX512 input and outputs that protect the splitter against damaging voltages up to 120 volts. Indicators on each output display power and termination status. Indicators on the input display signal present and valid DMX signal. The 125EE is designed to work on any voltage between 90 and 240 volts.

Doug Fleenor Designs 125EE Specifications:
