Plusrite 7277 BALU1000-CWA/V5 1000W HID High Pressure Sodium Ballast Kit 120/208/240/277/480V

The Plusrite 7277 BALU1000-CWA/V5 is a 1000-watt magnetic high pressure sodium ballast kit designed to operate ANSI S52 high pressure sodium lamps. Featuring five-tap 120/208/240/277/480V input capability, a Constant Wattage Autotransformer (CWA) circuit type, and a complete pre-wired component kit, this ballast delivers dependable starting and operating performance for commercial, industrial, and outdoor HID lighting systems.

This ballast kit is engineered for multi-voltage installations and includes the ballast, oil-filled capacitor, ignitor, mounting bracket, and wiring components required for high pressure sodium lamp operation. Its CWA design provides stable lamp output, high power factor operation, and dependable compatibility with ANSI S52 high pressure sodium lighting systems.

Operating from 120/208/240/277/480V input, the ballast consumes 1100 input watts with maximum line currents of 9.50A (120V), 5.50A (208V), 4.75A (240V), 4.20A (277V), and 2.31A (480V). The ballast measures 4.33 × 5.91 inches, weighs 27.0 lbs, utilizes coil temperature code C/B/C/C/C, requires a 26µF / 525V minimum capacitor, and uses wiring diagram E-V5.
