Keystone MPS-320A-P-KIT 320W Hid Ballast Kit 5 Tap

Product Description

The KEYSTONE MPS-320A-P-KIT is a 320-watt pulse start metal halide HID ballast kit designed for commercial and industrial lighting applications. This core and coil, constant wattage autotransformer (CWA) ballast operates on a 5-tap voltage configuration, accepting input at 120, 208, 240, 277, or 480 volts to suit a wide range of electrical service types. The kit ships complete with a dry film capacitor rated at 21 microfarads, a pre-wired igniter, a mounting bracket, and all associated hardware. ANSI code M132 confirms compatibility with the correct lamp family. Licensed electricians perform installation as part of HID fixture service or retrofit work.

This ballast kit is suited for commercial, industrial, and institutional environments where 320-watt pulse start metal halide sources are specified. Typical applications include high-bay warehouse lighting, outdoor area lighting, sports lighting, and large retail spaces. The 5-tap input range makes this unit flexible across facilities with varying distribution voltages, reducing the need to stock multiple ballast configurations. The pre-wired igniter simplifies field assembly and reduces wiring time during fixture service.

Compatibility

Designed for use with 320-watt pulse start metal halide lamps conforming to ANSI code M132. The 5-tap input accepts 120, 208, 240, 277, and 480-volt circuits. No additional specific model or system compatibility was stated in the product data.

Installation Notes

Installation must be performed by a qualified, licensed electrician in accordance with the National Electrical Code (NEC) and any applicable local codes. De-energize and lock out the fixture circuit before removing the existing ballast or connecting any wiring. Verify input voltage at the tap selection point matches the supply voltage before energizing. The pre-wired igniter is included and should not be substituted with an igniter of a different type, as mismatched igniters can damage the lamp or ballast.
