It converts 230V mains to 12V AC output and incorporates thermal cut-out, overload protection and short circuit protection to prevent damage from overcurrent or overheating. The unit functions as a safety isolating transformer with Class II double insulation, removing the need for an earth connection.\u003c\/p\u003e\n\u003cp\u003eDesigned for residential and commercial installations where recessed halogen downlights or low-voltage display lighting require protected power delivery, the T02 fits inside ceiling voids, under-cabinet spaces and lighting plenums. The 120mm length and 30mm width allow it to be tucked into joists or fitted within shallow ceiling depths. The 0.2m output cable terminates in push-fit connectors for quick connection to lamp holders or distribution blocks.\u003c\/p\u003e\n\u003cp\u003eThe polycarbonate housing carries an IP20 rating, making it suitable for dry indoor locations but not bathrooms or outdoor use. The transformer is dimmable when paired with trailing-edge or leading-edge dimmers rated for inductive loads — confirm compatibility with your specific dimmer model before installation. The thermal cut-out activates if internal temperature exceeds safe limits, shutting down output until the unit cools, then auto-resetting.\u003c\/p\u003e\n\u003cp\u003eAt minimum load the transformer draws 20W; at maximum it handles 60W total across all connected lamps. For a typical 20W halogen downlight that translates to 1-3 lamps per transformer. Running below the 20W minimum can cause flickering or hum; exceeding 60W triggers overload protection and shuts the unit down.\u003c\/p\u003e\n\u003ch5\u003eSpecification\u003c\/h5\u003e\n\u003ctable class=\"spec_table\"\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eLength\u003c\/td\u003e\n\u003ctd\u003e120 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eHeight\u003c\/td\u003e\n\u003ctd\u003e23 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWidth\u003c\/td\u003e\n\u003ctd\u003e30 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eConstruction\u003c\/td\u003e\n\u003ctd\u003ePolycarbonate\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eClass\u003c\/td\u003e\n\u003ctd\u003eII\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eIP Rating\u003c\/td\u003e\n\u003ctd\u003eIP20\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePrimary Voltage\u003c\/td\u003e\n\u003ctd\u003e230V 50Hz\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCable Length\u003c\/td\u003e\n\u003ctd\u003e0.2 m\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWarranty\u003c\/td\u003e\n\u003ctd\u003e1\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003ch5\u003eDownloads\u003c\/h5\u003e\n\u003cp\u003e\u003ca href=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0729\/8993\/3835\/files\/products_1783_datasheet.pdf\" target=\"_blank\"\u003eProduct Specification Sheet\u003c\/a\u003e\u003c\/p\u003e\n\u003cp\u003e\u003ca href=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0729\/8993\/3835\/files\/manual_743186.pdf\" target=\"_self\"\u003eProduct Manual\u003c\/a\u003e\u003c\/p\u003e\n\u003ch5\u003eFrequently Asked\u003c\/h5\u003e\n\u003cp\u003e\u003cstrong\u003eHow many 12V halogen lamps can this transformer power?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eThe T02 handles 20-60W total load.
