DIN-1DIMU4
Features
∙4 channels of forward or reverse phase dimming
∙Auto load detection
∙120 to 240 Volt 50/60 Hz operation (Not for 277 VAC operation)
∙Selectable non-dim mode
∙Extreme stability in noisy environments
Auto Load Detection
Each channel of the DIN-1DIMU4 is capable of auto- detecting the dimmable load type connected to it and selecting the appropriate operating mode to control that load. Reverse phase (trailing edge) mode supports incandescent and electronic low-voltage load types, while forward phase (leading edge) mode handles magnetic low voltage, neon, and other inductive load types. A non-dim mode is also selectable for switching of non-dimmable lighting fixtures. Any channel may be set for any mode, allowing one dimmer module to handle any combination of lighting types on four separately controlled circuits.
Phase-Synchronous Detection Circuitry
Proprietary Crestron zero-cross filter technology provides
The DIN-1DIMU4 is a 4-channel universal lighting control module designed to support dimming of both forward and reverse phase type loads. A single model supports 120 and 220-240 volt electronic and magnetic low voltage, incandescent, neon/cold cathode, 2-wire dimmable fluorescent, and non-dimmable lighting loads up to 5 amps per channel, 10 amps total.
∙Short circuit and overload protection
∙Master air-gap relay
∙Setup via front panel or software
∙Programmable functionality via DIN-AP2
superior immunity to noise on the power line, reducing lamp flicker and compensating for fluctuations in line voltage and frequency.
Short Circuit Protection
Built-in OCP (over current protection) prevents failure of the DIN-1DIMU4 caused by excessive loading or improper wiring of the outputs.
Master Air-Gap Relay
When all four channels are turned fully off, the internal master relay automatically opens, providing air-gap isolation that allows safe servicing and changing of light bulbs on all four controlled circuits.
