The City Theatrical PSCR30R-240 is a specialized, high-current DMX power supply unit designed specifically to drive City Theatrical's AutoYoke and Auto Iris mechanical accessories for theatrical and studio lighting fixtures. This unit converts standard 100-240V AC mains power into a regulated 30V DC, 8A output, providing the substantial power required to operate motorized irises, dowsers, and other mechanical effects attached to ellipsoidal and moving lights. It features DMX512 control input, allowing the mechanical accessory's operation (such as iris size or dowser position) to be integrated seamlessly into a lighting console's cue stack for precise, repeatable control. The robust metal housing includes comprehensive cooling and protection circuits, ensuring reliable operation under the high load demands of theatrical productions.

The power supply is engineered for safety and ease of use in professional environments, featuring terminal block connections for both power input and output to the accessory. It includes status LEDs for power and signal indication, and a recessed DMX address dial for setting the unit's starting DMX channel. Its design prioritizes delivering clean, stable power to prevent motor stalling or erratic movement, which is critical for maintaining consistent performance during shows. The PSCR30R-240 is an essential component for lighting designers who require automated mechanical control within their conventional or moving light rigs, enabling dynamic effects like gradual iris changes or instantaneous blackouts that enhance the visual storytelling on stage.

As a dedicated interface between a DMX control system and power-hungry mechanical accessories, this power supply unit provides the necessary muscle and control integration. Its robust construction and focused functionality make it a trusted backstage tool for creating sophisticated mechanical lighting effects in theater, television, and live event production.
