Vari-Lite 53804-135 - Dual 20A Dimming, Relay and Constant Module for RigRack or Retrofit C21 Modular Power Rack Enclosures in Gray Finish

The Vari-Lite 53804-135 Dual 20A Dimming, Relay, and Constant Module is a versatile, high-performance power module designed for use in the RigRack and Retrofit C21 Modular Power Rack Enclosures. This module enables venues to upgrade their existing power infrastructure, allowing them to integrate modern luminaires and control systems without the need to replace their entire setup. With the ability to support dual 20A power loads, this module offers reliable and flexible power control for a wide range of production environments.

Built with a dual 20A power capacity, the 53804-135 module can be easily swapped in and combined with other power control modules, including dimmers and relays, to meet the specific needs of each production. This modular design provides flexibility, allowing users to select and configure the power modules that best suit the demands of the lighting system, whether for theater, concert venues, or other entertainment settings. The module is plug-in compatible, ensuring quick and straightforward integration into existing racks.

The module features a combination of dimming, relay, and constant power functionality. The dimming operation utilizes a Dual SCR (Silicon Controlled Rectifier) system that offers forward-phase dimming, which is ideal for many types of theatrical lighting setups. The relay functionality allows for mechanical on/off switching, while the constant mode ensures an uninterrupted power supply, making it suitable for fixtures that require steady, undimmed power. This versatile combination makes the module an essential tool for managing a variety of lighting fixtures, including both dimmable and non-dimmable loads.

With a rise time of 500?s, the Dual SCR Dimmer mode allows for fast and precise control over lighting output. This ensures smooth transitions and reliable performance, especially in environments where quick adjustments are necessary. The module is also equipped with magnetic circuit breakers for added protection against electrical faults, ensuring safe operation under high-load conditions.

Constructed from heavy-duty aluminum and featuring an integrated heat sink, the 53804-135 module is designed to withstand the demands of a live performance environment. Its robust construction ensures optimal cooling and durability, while the IP20 ingress protection rating makes it suitable for indoor use in controlled environments. The module operates within a temperature range of 32°F to 104°F and can tolerate humidity levels from 0% to 95%, non-condensing.

For ease of installation and use, the 53804-135 module is UL/cUL recognized and ETL/cETL listed, ensuring compliance with industry safety standards. This module is ideal for venues looking to enhance their power control systems while maintaining the flexibility to adapt to future needs. Whether upgrading existing racks or building new systems, the 53804-135 module offers reliable and efficient power control in a user-friendly package.
