It steps mains voltage down to a 24-volt control circuit, providing power to the low-voltage controls that operate the burner and fan sequences. This transformer is a direct-fit replacement component installed by licensed HVAC technicians during routine service or control system repairs. At 50VA, it supplies adequate capacity for standard low-voltage thermostat and control board circuits found in commercial and industrial heating applications.\u003c\/p\u003e\u003cp\u003eThis transformer is specified for use in GG and XF Series gas-fired unit heaters. These unit heaters are commonly installed in commercial and industrial environments such as warehouses, garages, and manufacturing spaces. The transformer supports the low-voltage control circuit that manages burner ignition sequencing and blower operation within those systems. Technicians replacing a failed control transformer should verify input voltage availability and output load before installation.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e50VA capacity supports standard low-voltage HVAC control circuits\u003c\/li\u003e\n\u003cli\u003e115-volt primary to 24-volt secondary step-down configuration\u003c\/li\u003e\n\u003cli\u003eSpecified for GG and XF Series gas-fired unit heaters\u003c\/li\u003e\n\u003cli\u003eDirect OEM replacement for reliable control circuit restoration\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with GG and XF Series gas-fired unit heaters as specified in the product application data.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified HVAC technician. Disconnect and lock out all power to the unit heater before removing the existing transformer or making any wiring connections. Verify the primary voltage at the disconnect matches the transformer input rating before energizing. Follow all applicable local codes and the National Electrical Code when wiring low-voltage control circuits.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eTransformer Rating\u003c\/strong\u003e: 50VA\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Voltage\u003c\/strong\u003e: 115 volts\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSecondary Voltage\u003c\/strong\u003e: 24 volts\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eApplication\u003c\/strong\u003e: GG and XF Series Gas Fired Unit Heaters\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: MESTEK\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: j14r03245-012\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"MESTEK","offers":[{"title":"Default Title","offer_id":51233967145266,"sku":"J14R03245-012","price":169.78,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/307633360.jpg?v=1780113437","url":"https:\/\/voomisupply.com\/products\/mestek-j14r03245-012-transformer-50va-115-24v","provider":"Voomi Supply","version":"1.0","type":"link"}
