It runs on a dual-voltage input of 120\/277 VAC at 50\/60 Hz, making it suitable for both standard and commercial voltage applications. The high power factor (HPF) design delivers a power factor of 0.97 to 0.99 and keeps total harmonic distortion (THD) at or below 15 percent. Ballast factor range of 0.8 to 1.2 gives installers flexibility across light output levels. The unit is UL listed for use in Canada and the United States and is RoHS compliant. It measures 5 inches long by 3 inches wide by 1.38 inches high and ships with a mounting bracket, wire lead, and hardware included.\u003c\/p\u003e\n\u003cp\u003eThis ballast is used in commercial and residential fluorescent lighting fixtures that accept 4-pin T5 compact fluorescent lamps with GX24q, G24q, GR10q, or 2G11 lamp bases. Compatible lamp types include CFTR42W\/GX24q, CFTR32W\/GX24q, CFQ26W\/G24q, CFTR26W\/GX24q, FC9T5 22W, CFTR57W\/GX24q, FT40W\/2G11, FT36W\/2G11, FT24W\/2G11, CFS28W\/GR10q, and FC9T5\/FC12T5. Typical install scenarios include troffer retrofits, downlight cans, and task lighting fixtures in commercial office, retail, and institutional environments. The parallel wiring configuration maintains lamp operation if one lamp fails. Licensed electricians handle ballast replacement as part of routine fixture maintenance or lamp-type upgrades.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eRapid start circuit supports 1 or 2 lamp operation up to 42W per lamp\u003c\/li\u003e\n  \u003cli\u003eDual input voltage 120\/277 VAC accommodates standard and commercial branch circuits\u003c\/li\u003e\n  \u003cli\u003eHigh power factor (HPF) rated at 0.97 to 0.99 reduces reactive load on the circuit\u003c\/li\u003e\n  \u003cli\u003eBallast factor range of 0.8 to 1.2 allows light output adjustment across four operating modes\u003c\/li\u003e\n  \u003cli\u003eParallel wiring keeps remaining lamp lit if one lamp reaches end of life\u003c\/li\u003e\n  \u003cli\u003eEnd-of-life lamp protection circuit prevents overheating from a failed lamp\u003c\/li\u003e\n  \u003cli\u003eIncludes mounting bracket, wire lead, and hardware for direct installation\u003c\/li\u003e\n  \u003cli\u003eUL listed (Canada and US), RoHS compliant, meets ANSI\/IEEE C62.41\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eCompatible lamp types stated by the manufacturer: CFTR42W\/GX24q, CFTR32W\/GX24q, CFQ26W\/G24q, CFTR26W\/GX24q, FC9T5 22W, CFTR57W\/GX24q, FT40W\/2G11, FT36W\/2G11, FT24W\/2G11, CFS28W\/GR10q, and FC9T5\/FC12T5.

Always shut off and lock out the branch circuit breaker before opening the fixture housing and disconnecting the existing ballast. Follow NEC requirements for fixture wiring, and verify that the replacement ballast input voltage matches the branch circuit voltage before energizing. Do not operate the ballast outside its rated lamp type list, as mismatched lamps can trigger end-of-life protection or cause premature ballast failure.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLamp Wattage\u003c\/strong\u003e: 42W maximum\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Lamps\u003c\/strong\u003e: 1 or 2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInput Voltage\u003c\/strong\u003e: 120\/277 VAC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInput Current\u003c\/strong\u003e: 0.13\/0.25\/0.35\/0.7 amps\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInput Power\u003c\/strong\u003e: 31\/50\/67\/84W\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFrequency Rating\u003c\/strong\u003e: 50\/60 Hz\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePower Factor\u003c\/strong\u003e: 0.97\/0.98\/0.99\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCircuit Type\u003c\/strong\u003e: HPF\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStarting Type\u003c\/strong\u003e: Rapid Start\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBallast Factor\u003c\/strong\u003e: 0.8\/0.95\/1.0\/1.2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum THD\u003c\/strong\u003e: 10\/15 percent\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Starting Temperature\u003c\/strong\u003e: -18 degrees C\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLamp Style\u003c\/strong\u003e: 4-Pin T5\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWiring\u003c\/strong\u003e: Parallel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDimensions\u003c\/strong\u003e: 5 inches L x 3 inches W x 1.38 inches H\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCase Material\u003c\/strong\u003e: Plastic\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCase Temperature Rating\u003c\/strong\u003e: 75 degrees C\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCase Style\u003c\/strong\u003e: S1\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eApplicable Standard\u003c\/strong\u003e: ANSI\/IEEE C62.41\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eApprovals\u003c\/strong\u003e: UL (Canada and US)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRoHS Compliant\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCountry of Origin\u003c\/strong\u003e: China\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eIncludes\u003c\/strong\u003e: Mounting bracket, wire lead, and hardware\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\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: KTEB-242-UV-RS-DW-KIT\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KEYSTONE","offers":[{"title":"Default Title","offer_id":51283927531826,"sku":"KTEB-242-UV-RS-DW-KIT","price":36.39,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/309279495.jpg?v=1781063402","url":"https:\/\/voomisupply.com\/products\/keystone-kteb-242-uv-rs-dw-kit-42w-cfl-electronic-ballast","provider":"Voomi Supply","version":"1.0","type":"link"}
