What are the power requirements for Sigma S, X, and L products?
Sigma power requirements vary significantly by product type, display size, brightness, and configuration even though the interface architecture is standardized. As guide-level typical references, Sigma S TDS models range from about 3.5 W for S7 up to about 39 W for high-brightness S215, Sigma X Open Frame models range from about 5 W for X7 up to about 45 W for X215, and Sigma L LCD models range from about 3.1 W to about 38.6 W depending on model and brightness. Standard Sigma L models use 3.3 V LCD logic power and 12 V backlight power, with model-dependent current. These values are typical reference values, not final design maximums. Please ask AMT for the latest model datasheet before finalizing the power supply, cable gauge, connector-contact current, voltage-drop margin, or thermal design.
