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.\u003c\/p\u003e\u003cp\u003eThis 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.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e320W pulse start metal halide lamp type, ANSI code M132\u003c\/li\u003e\n\u003cli\u003e5-tap voltage rating: 120, 208, 240, 277, and 480 volts\u003c\/li\u003e\n\u003cli\u003eCore and coil CWA circuit type for stable lamp wattage regulation within 10 percent\u003c\/li\u003e\n\u003cli\u003eIncludes dry film capacitor (21 MFD), pre-wired igniter, mounting bracket, and hardware\u003c\/li\u003e\n\u003cli\u003eCopper and aluminum winding material; insulation class rated to 180 degrees C\u003c\/li\u003e\n\u003cli\u003eUL listed for use in Canada and the United States; RoHS compliant\u003c\/li\u003e\n\u003cli\u003eCountry of origin: China\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with 320-watt pulse start metal halide lamps conforming to ANSI code M132.

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.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eLamp Type\u003c\/strong\u003e: Pulse Start Metal Halide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLamp Wattage\u003c\/strong\u003e: 320 W\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eANSI Code\u003c\/strong\u003e: M132\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCircuit Type\u003c\/strong\u003e: CWA (Constant Wattage Autotransformer)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBallast Type\u003c\/strong\u003e: Core and Coil\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVoltage Rating (Input)\u003c\/strong\u003e: 120\/208\/240\/277\/480 volts (5-Tap)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOpen Circuit Voltage\u003c\/strong\u003e: 291 volts\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCapacitor Voltage\u003c\/strong\u003e: 345 volts\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInput Current Rating\u003c\/strong\u003e: 3.2 \/ 1.84 \/ 1.6 \/ 1.38 \/ 0.8 amps\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFrequency Rating\u003c\/strong\u003e: 60 Hz\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCapacitor\u003c\/strong\u003e: 21 MFD, Dry Film\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWattage Regulation\u003c\/strong\u003e: 10 percent\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWinding Material\u003c\/strong\u003e: Copper and Aluminum\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMinimum Starting Temperature\u003c\/strong\u003e: -30 degrees C\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCapacitor Temperature Rating\u003c\/strong\u003e: 90 degrees C\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsulation Class\u003c\/strong\u003e: 180 degrees C\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIgniter Type\u003c\/strong\u003e: Pre-Wired\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eKit Contents\u003c\/strong\u003e: Capacitor, Igniter, Mounting Bracket, Hardware\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eApprovals\u003c\/strong\u003e: UL Listed (Canada and US), RoHS Compliant\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Dimensions\u003c\/strong\u003e: 9.0 inches L x 7.0 inches W x 5.0 inches H\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCountry of Origin\u003c\/strong\u003e: China\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: KEYSTONE\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: MPS-320A-P-KIT\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KEYSTONE","offers":[{"title":"Default Title","offer_id":51283906953522,"sku":"MPS-320A-P-KIT","price":189.38,"currency_code":"USD","in_stock":false}],"url":"https:\/\/voomisupply.com\/products\/keystone-mps-320a-p-kit-320w-hid-ballast-kit-5-tap","provider":"Voomi Supply","version":"1.0","type":"link"}
