Hopefully this clarifies how to wire one of our transformers. Similarly, any two phases on the wye configuration should be connected to the gray and black wires on the transformer for a 480 Vac primary. It doesn’t matter which phase goes to which wire.įor the above wye configuration, you would connect your neutral (GRAY) and any phase to the black and brown wires on the transformer for a 277 Vac primary. If you wanted to use 240 Vac on the primary, you would take any two of the three phases and connect them to the orange and black wires on the transformer. Then you would either connect phase A or C (BLACK or BLUE) to the 120 Vac tap on the transformer (Wht). If you wanted to connect 120 Vac to the primary, you would connect your neutral (WHITE) to the transformer Comm (Blk). Let’s say you want to connect the above delta configuration to our TR50VA015. Take a look at the wiring diagram for our TR50VA015: It’s that easy!įor the sake of clarity let’s do some examples. Then separately insulate each of the unused wires. Once you know which two wires have the voltage for the tap you want, simply connect one power wire to the wire on our transformer with the voltage tap you want, and the other power wire to the wire on our transformer labeled “Comm”. If you don’t know which wire is which, you can always measure it using your multimeter. Knowing which voltage is between which two wires is key when installing one of our multi-tap transformers. Usually, between neutral and a phase is a smaller voltage, and between two different phases is a larger voltage. This allows each configuration to provide two to three different voltages. ClimaTek Upgraded Replacement for Goodman Furnace Fan Control Circuit Board B13707-35 B1370735 B1370735S. (50 Pcs) MCIGICM 3 Amp Standard Fuse, 3A Blade Automotive Fuse for Car Truck. 2 Answers Sorted by: 63 The solid/dashed lines on wires like the ones pictured in your question are used to indicate polarity e.g. The main point to get from this is that your incoming power typically has three phases and one neutral. This item: Goodman 0130M00138S 240V to 24V Transformer. Wiring diagrams are visual representations of how electrical components are connected, and they are essential for a successful and safe installation. Please note that not every delta or wye set up will have these voltages, these are just two examples. Octoby Ana Olpah All You Need to Know About Common Wire On 24 Volt Transformer Working with wiring diagrams is an important part of any electrical project. The wye configuration also looks a bit like a flux capacitor from Back to the Future if that helps. Delta ConfigurationĪn easy way to remember this is that the delta configuration looks like a delta symbol, and the wye configuration looks like the letter “Y”. Typically, they’re in either a delta or wye configuration. Type Power Class Class 2 Input Voltage 120/208/240 Primary Connection Wire Leads Voltage Output 24 Mounting Foot Mount Secondary Connection Wire Leads VA. Luckily, the solution is an easy one to remember once you know it.Ī large part of being able to figure this out is knowing how your 3-phase incoming power is set up. This is understandable, considering all the wires involved. I’ve noticed that the Opensprinkler board is expecting a 2-wire connection from the transformer, yet the Hunter transformer that I’ve already got is a 24VAC/1-AMP unit, having a 3-prong electrical plug and three wires going to the Hunter Pro-C controller: AC1 (yellow), AC2 (yellow), and GND (green).Occasionally we get calls from customers asking which wires to connect to our multi-tap transformers. It will be replacing a Hunter Pro-C controller that was installed by the guys who installed a 9-zone irrigation system recently. Transformer windings have a phase relationship, but its typically not important for power supplies. Voltage This is the amount of electrical potential measured in volts. Standard control transformer, 40 VA, 240 VAC input 24 VAC output. The following list defines some of the more common terms: Wire This is the physical connection between components. Standard Control Transformers > 240 V AC Primary Control Transformers. If 4 or more wires have continuity, then you have a multi-tap transformer winding. Wiring diagrams are drawn using standard symbols and lines to represent the different components and connections. I’m reading up to prepare for the install soon as it arrives. If 3 wires have continuity, then you probably have a center-tap winding (+, 0, -) If only 2 wires have continuity, then that is a simple winding. I’ve just ordered an Opensprinkler unit + expansion board.
