Vari-Lite 53805-134 - Dual 20A IGBT Module for RigDim 120V Enclosure in Black Finish

The Vari-Lite 53805-134 Dual 20A IGBT Module for RigDim 120V Enclosure is a high-performance dimmer module designed to provide reliable, efficient, and precise dimming control for a variety of lighting loads. Utilizing IGBT (Insulated Gate Bipolar Transistor) technology, the module ensures that inrush current is controlled accurately, which is critical for preventing lamp damage. This technology also eliminates the need for chokes, resulting in quieter operation and reduced lamp noise, particularly for incandescent lamps.

The 53805-134 module is built for seamless integration with the RigDim Enclosures, offering easy installation and maintenance. The modules feature identical mounting dimensions, allowing for interchangeable use in any RigDim system. It's important to note that while installing this dual dimmer module, caution must be exercised to ensure that quad dimmer modules are not mistakenly installed in spaces designed for dual modules.

The module features a "Focus Button" on each circuit, enabling manual operation and testing. By tapping the focus button quickly, users can toggle the circuit on and off. If the button is pressed and held, the dimmer will ramp up to full intensity. If the button is released before reaching full intensity, the dimmer will stop at the corresponding output level. This feature allows for precise control during setups and testing, making it a valuable tool for lighting designers and technicians. For safety, it is crucial that power is turned off during installation to avoid exposure to dangerous voltage and potential damage to the device. It is recommended that installation be performed by a qualified electrician.

The module is designed for use with a wide range of loads, including incandescent, inductive, magnetic low voltage, and electronic low voltage. It provides consistent dimming performance with a rise and fall time of 800?S, regardless of load size. The cooling system is based on natural convection, making it fanless and ideal for environments where noise is a concern, such as nearstage locations.
