1 SECTION VI LO VOLTAGE LIGTING TRANSFORMERS & POER SUPPLIES Low Voltage Lighting Power Supplies A greater selection for your indoor and outdoor low voltage lighting projects hy Low Voltage? Acme s Low Voltage Lighting products provide a safe, long lasting, highly reliable power source; a perfect selection for landscape applications as well as interior use. Low voltage lighting is a creative medium with unlimited application possibilities. Low voltage lighting benefits include: Precision beam control More light intensity per watt Less radiated heat Greater efficiency Longer life Safer to use Easy installation A high return on end-user investment Acme Advantages Greater selection Acme offers one of the largest selections of low voltage lighting transformers in the industry. The addition of our premium line (Group I) that includes a photocell and 24-hour timer and the versatile Group V transformers gives the landscape architect or contractor almost unlimited application possibilities. Please use the convenient Selection Guide on the facing page to aid in your selection. More value Acme low voltage transformers and power supplies are available in a wide range of options and models that are all UL listed for use indoors or outdoors. All Acme products are backed by a 10-year limited warranty (see inside back cover for details). More Power Power supplies are available in ratings of 100 through 1500 and transformers in ratings of 100 through 1000 ; Group VI Buck Boost in.05 through 10 KVA. More convenience Screw lug output terminals on Group I, II and III power supplies provide fast low voltage connections regardless of transformer location. Just slip your wires into the lug and tighten there s no wrapping the wire around a screw post. Groups IV, V and VI transformers have copper lead wires for hardwiring. Circuit breakers for instant reset (except pool and spa and Buck Boost). No fumbling with fuses. Generous wiring compartment, too! More protection A full fault current carrying Faraday Shield (except Buck Boost) prevents 120 volts from reaching the 12 volt side, as required by UL-1571 and UL Features and Options The convenient Selection Guide on the facing page provides you with the data you need to select the product that best meets your requirement. Complete product selection data, dimensions and wiring diagrams are contained on the following pages. If you need help in your selection, or if you have questions, just call technical services at

3 ow To Size Your Power Supply Easy Two-Step Selection 1. Add the total lamp wattage of each circuit you plan to use. For example: if you have 2 circuits, each with four 25 watt lamps, your total wattage is: 2 circuits x 4 lamps = 8 lamps x 25 watts = 200 watts. 2. Go to the appropriate selection chart. The catalog number identifies the power supply size and output voltage (see example below). You won t find the exact 200 watts needed, so go to the next highest catalog number TLV S. This leaves you 50 watts of reserve power available for other low voltage applications. See chart below for recommended wire sizes and voltage drop. If you use a power supply with a dual 12/24 volt secondary, each 12 volt circuit is rated at one half the total power supply wattage. Example: A TLV SC has two 12 volt 125 watt output circuits. Refer to Interpreting Power Supply Catalog Numbers for further explanation of catalog numbers. immer Notice Only use dimmers designed and rated for magnetic loads. Consult the dimmer manufacturer for recommendations regarding your lighting application.

8 Buck- Boost Transformers The No-Frills Low Voltage Lighting Alternative Buck-Boost Transformers offer a no-frills approach to low voltage lighting. (See Chart Below) A typical Buck-Boost application is 120 volts in and 12 volts out for low voltage lighting or control circuitry. In most applications, this low voltage isolation transformer is field connected as an autotransformer. For more information on Buck-Boost Transformers, refer to the next section in this catalog.
