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.
