AC Light Dimmer 6-Channel x 500W

This high-power 6-Channel Pulsar series AC light dimmer offers 256 levels of computer-controlled brightness with lighting effects.  This controller is equipped with dual aluminum heat-sinks and a metal enclosure.  This is the Dual Circuit version, which requires connection to two 15-Amp breakers.  Capable of dimming up to 500 Watts per channel, this controller capable of dimming a total of 3000 total AC Watts!  Dual fuse provides protection from short circuits.  This is big and heavy controller, perfect for high-power light dimming applications.


The Pulsar series controllers are designed to offer an industrial grade light dimming solution with a heavy emphasis of connectivity to computers using a wide array of interface technologies. Whether you need to control lights across the room or from the other side of the planet, we have a solution available that offers flicker-free operation in an industrial design built to last many years.  The Pulsar Series controllers have many features that make them extremely easy to use. They are designed for hard-wired installation and are designed to operate every hour of every day.

How it Works

The Pulsar Series controllers wait for a light dimming command. When a command is received, the lights will fade or brighten according to your instructions. The Microprocessor that powers the Pulsar Series is capable of simultaneously handling communications while dimming operations are in progress in the background, keeping your computer free to service other tasks.

The Pulsar Series controllers have 5 buffers that work together to handle your light dimming requests. Buffer number one is used to immediately set the light level to the brightness you desire. Buffer number two is what we call a migration buffer. When a brightness level is stored in the migration buffer, the light levels will gradually change (automatically) to match the migration buffer level. This is particularly useful if you want lights to fade on and off. Instead of writing all the code to fade the lights on and off, you simply tell the second buffer what level you want the lights to migrate to. Since the lights will fade automatically, your computer is free to service other tasks.

Buffers three and four are used to define how fast lights go on and off respectively. So lights can turn on instantly and fade out slowly. Or you can use buffer 5 to set the on and off rate to the same speed (using one command). This allows lights to fade on and off at the same rate.

You have 255 levels of brightness control at your disposal. A brightness level of 0 is off and a value of 1 is very dim (and 254 is full brightness). You can change the AC timing characteristics so that 1 is extremely dim (ideal for LED lighting applications) or so that 1 is an actual usable brightness (for incandescent lighting applications). We have included 3 profiles to help get you started, and you can change our settings to match the types of lights you intend to control.

Just for fun, we added a few lighting effects to help us test out the speed of the microprocessor (requires a controller with 3 or more channels to see the lighting effects). The Pulsar series controllers are not designed for stage lighting applications, as DMX controllers are better suited for lighting effects. And while we are on the subject of DMX… (we know we are going to get this question a lot)… so here goes…


First, it should be stated that we are huge fans of DMX! DMX is a wonderfully mature standard and is the best choice for many lighting effect applications. However, the Pulsar Series light dimmers are not compatible with DMX software or hardware. It is not likely that we will ever make any devices compatible with DMX technologies, as we have a very different goal in mind. We believe DMX to be a wonderful standard, and there are many manufacturers to choose from who offer mature DMX light dimming solutions. So if you need DMX compatibility, the Pulsar series controllers should not be considered. If you need a wide range of connectivity options, or if you need control of your lights from anywhere in the world, we hope you will consider the Pulsar series controllers.

Communication Options

Pulsar Series controllers were designed to work with a wide variety of communication technologies.  Choose the communication technology that best suits your needs during the order customization process.  Below you will find a complete list of supported computer interface technologies.

Ethernet Communications Module

Ethernet TCP/IP to Serial Converter

Control NCD devices using standard Ethernet TCP/IP communications.  Simply open a socket and send and receive TCP/IP data to control our devices.  Our Ethernet TCP/IP Communication modules feature our 3rd Generation Ethernet to Serial communications module.

ZRS RS-232 Serial Module

RS-232 Serial

NCD RS-232 Serial Communication modules make it easy to integrate the worlds most prolific communication standard.  Easily interface to desktop PCs and laptops for easy control via standard serial commands.  Most NCD devices typically default to 115.2K Baud; however, older low-cost devices implement 9600 baud data rate as the predominate standard.

WiFi Bluetooth USB 3 in 1 Module with MQTT Support

Control NCD devices using standard WiFi TCP/IP communications or use the integrated Bluetooth for simple wireless computer to device interface using a wireless virtual COM port.  Use the USB port for control over a virtual COM port for easy connectivity.  Integrated web server allows control of select NCD relay controllers using a built-in non-secure web page.  This is a low-cost solution that lets you try different solutions with easy setup using a integrated Web Page User Interface for all Configuration settings.  Connect to a MQTT Server over WiFi for remote operation over the internet.


Pulsar Series Compatibility Notes

Pulsar series controllers were designed for use with AC Incandescent light bulbs, and are not for use in AC Motor Speed control applications under any circumstances.  Mercury Vapor, CCLF, and Florescent (tube) lights will damage the Pulsar controller and/or the circuitry built into these kinds of lights.  Note that incorrect wiring of the AC mains will damage this controller beyond repair and may damage your computer as well.  Proper Hot, Neutral, and Grounding is essential for proper operation of this device.  This controller is rated for use at 120VAC at 60Hz, and will not work at 50Hz.  We have had customers use the Pulsar series controllers to control large LCD glass transparency panels with excellent results provided a loading resistor is used on the output.  Other customers have successfully used the Pulsar series to control heating elements.  We have not directly tested Pulsar in these applications, but it is possible that Pulsar can be used in other resistive AC control applications.

Ethernet TCP/IP Compatibility Notes

This device periodically sends UDP Packets on port 13,000, which help identify the IP address of this device on your network.  This device sends UDP Packets to to help users access this device from the internet (this feature can be disable).  Remote access over the internet requires users to configure Port Forwarding on the router that is associated with the WiFi communications module.  Port Forwarding is outside the scope of NCD technical support.  Please visit for instructions on configuring most routers for port forwarding.

RS-232 Serial Compatibility Notes

The NCD RS-232 Serial communications module is compatible with standard RS-232 signals (+/-10VDC), which are not directly compatible with UART signals from a microprocessor.  If you are working with Arduino, Microchip PIC, or other common microcontroller, a communications module is not required.   Microcontrollers will directly talk to the on-board processor of all NCD controllers.
