Chromophare D-Series Operating Room Light Component | Voltage Regulator and Light Intensity Power Circuit Board | Model 65604-4-B | Central Axis Suspension Control Element

The Berchtold Chromophare 65604-4-B is a professional-grade, hospital-legacy printed circuit board (PCB) assembly explicitly engineered to manage electrical power distribution and light intensity regulation within premium Berchtold Chromophare D-Series halogen and early-generation LED surgical lighting systems (including the D650plus, D540, D530plus, and D300 illumination heads). Functioning as the primary solid-state voltage regulator module, this circuit board steps down, stabilizes, and modulates incoming alternating current (AC) or direct current (DC) line voltage to deliver a clean, continuous power supply directly to the surgical light head's central lamp elements or LED arrays. This precision voltage suppression eliminates subtle light head flickering, preserves optimal color rendering indices (CRI), manages user-selected lux intensity dimming adjustments from the wall control pad or suspension arm keypad, and protects expensive illumination filaments from catastrophic power spikes, guaranteeing a stable, shadow-free, and uniform column of high-intensity light over high-stakes, long-duration operating room fields.
