Vari-Lite 53805-233 - Quad 10A IGBT Module for RigDim 277V Enclosure in Black Finish

The Vari-Lite 53805-233 Quad 10A IGBT Module for RigDim 277V Enclosure is a high-performance, reliable dimming solution designed for professional theatrical and entertainment venues. Equipped with IGBT (Insulated Gate Bipolar Transistor) dimming technology, this module offers precise control over inrush current, effectively eliminating the need for chokes, and provides superior protection against short circuits. By operating with IGBT technology, it enhances the efficiency of dimming systems and helps reduce lamp noise, particularly on incandescent lamp types, ensuring a quieter and smoother performance.

The 53805-233 module is designed to be installed in the RigDim 277V Enclosure, providing an easy-to-swap, modular approach to managing lighting systems. It features four circuits, each capable of handling up to 1000W of load, supporting a variety of load types, including incandescent, inductive, magnetic low voltage, and electronic low voltage systems. With a minimum rated load of 0.5W per circuit, this module provides versatile control across a wide range of lighting configurations and load types.

Each circuit in the RigDim 53805-233 module is equipped with a "Focus Button," allowing users to manually control the power output. The focus button offers multiple functions: a quick tap turns the circuit on to full intensity, and tapping it again quickly turns the circuit off. Additionally, pressing and holding the focus button ramps the dimmer up to full intensity. If the button is released before full intensity is reached, the dimmer will stop at the relative output, allowing precise control over the lighting levels. This makes it easy for operators to quickly adjust lighting during setup or performance without additional tools.

In terms of installation, the RigDim 53805-233 module follows a standard mounting dimension, ensuring that it can be easily swapped with other RigDim modules in the same enclosure. However, it's important to note that care should be taken not to install quad dimmer modules in spaces that are wired for dual dimmer modules, as this could cause improper operation or damage. It is recommended that a qualified electrician perform the installation to ensure safety and proper functionality, as working with power can expose users to dangerous voltages.

RigDim 53805-233 operates on 277VAC power with a maximum input current of 150A, providing robust and reliable performance in high-demand environments. The transition time of the dimming system is set at 800?S for both rise and fall, independent of load size, ensuring smooth and precise control over the lighting output. With natural convection cooling, the module operates silently, providing a fanless design that is ideal for quiet installations, such as those near stages where noise interference must be minimized.

The RigDim module is designed to withstand a wide range of environmental conditions. It operates efficiently within an ambient temperature range of 32°F to 104°F, with a relative humidity range of 5% to 95% non-condensing. This makes it suitable for a variety of climates and installation settings, ensuring long-lasting performance and reliability across diverse venues.
