Industrial 71A8473-001D NSNBC01 Remote IO Module

Philips Advance 71A8473-001D is a 400-watt magnetic HID ballast kit for a single lamp, marketed under the Advance brand as a 400 W HID ballast kit. It uses a core-and-coil magnetic design to regulate current and provide reliable ignition for HID lamps, a common configuration in standard 400 W installations. Retail listings consistently describe this model as a 400 W max, one-lamp HID ballast kit, confirming its single-lamp, magnetic ballast architecture rather than an electronic ballast. The part is cataloged in cross-reference guides as 71A8473-001D with the designation Magnetic HID and Core-and-Coil ballast family, reinforcing its traditional magnetic ballast construction. This combination of features—one-lamp, 400 W capacity, and magnetic core-and-coil design—defines its role in HID lighting systems where a straightforward, proven ballast solution is required.
