LumenDimM2 Miniature Two-Channel CRMX or W-DMX Wireless Dimmer

The LumenDimM2 is small two channel wireless DMX CRMX Lumenradio based dimmer ideal for bicolor LED tape. Provides all RC4 Series 3 features including cross-fade mode for easy color temperature control with warm-warm/cool-white LED sources.

External antenna is included in delivery.

It includes 19-bit dimming, which is eight times finer than 16-bit with a whopping 524,000 steps of resolution. The digital persistance for ISL dimming curve simulates the behavior of a tungsten lamp for LED with no visible stepping.

Device configuration can also be done with Remote Device Management (RDM) wired or wireless.

Many pulse-width-modulation (PWM) dimmers look good to the human eye, but produce banding, blinking, and other anomalies when used with video cameras. For this reason, all RC4 Series 3 dimmers provide multiple PWM frequencies.  Low frequencies are most efficient, ideal for high-wattage incandescent lighting. Mid frequencies improve the appearance of LEDs by eliminating visible strobing in human peripheral vision.  High frequencies eliminate video artifacts.  And finally, supersonic PWM frequencies, though least efficient for power handling, provide PWM dimming without audio interference when used near microphones and electrified musical instruments.

This dimmer can control the speed and direction of DC motors and the position of hobby servo motors.

For direction control, a second dimmer output can be used to flip a relay that reverses the DC motor connectors – polarity of power directly controls spin direction.

The LumenDimM2, and all RC4 Series 3 dimmers, provide a wired DMX data port.  In most cases this port is used to output data to nearby fixtures including fog machines, moving lights, and projector dousers.  The DMX port can also be configured as a DMX input, allowing the LumenDimM2 to be used as a wired dimmer.  In this mode, a comprehensive RDM implementation includes E1.37 dimmer configuration parameters, numerous status sensors (voltage, temperature, current), and each individual dimmer appears as an RDM sub-device.

The RC4 DMX miniplug port can used with a range of DMX adaptors, including 3-pin and 5-pin male and female XLR connectors.  The most common adaptor is the RC4DMX5FA with 5-pin female XLR connector.

Screw terminals are provided for connection of the power supply (DC IN) and load devices (DimA, DimB). The supply powers both the internal electronics and the connected loads. Dimmers switch on the negative side of the circuit, ideal for common-anode (common positive) LED tape. Dimmer output voltage is precisely the DC power input voltage with no appreciable losses within the 16A total power handling limit of the device.
