![]() ![]() The engine runs on 12V and draws 15A and thus has a power consumption of 180W (12 x 15). ![]() So the power consumption is 24 x 30 = 720W.Įxample 3: Suppose I have another Minn Kota Endura C2 50 LBS that I am running in gear / speed setting 2. This goes up when the number of amps also goes up.Įxample 2: Suppose I have a 24V Minn Kota Terrova 80 LBS bow motor that draws 30 amps. This is the amount of energy consumed by a device and therefore an indication of how powerful it is. Power is the voltage multiplied by the number of amps, or W = V x A. The voltage has remained the same but the number of amps has gone up. The engine still runs on 12V but now pulls 25A. I decide to go a little faster and I switch to gear / speed setting 4. The trolling engine runs on 12V and currently draws 15A. An electrical device usually works on a fixed voltage, but the amount of amps it draws can vary depending on, for example, the position of your trolling engine (a trolling engine at full throttle draws more amps than in half throttle for instance).Įxample 1: Suppose I have a Minn Kota Endura C2 50 LBS that I am running on gear / speed setting 2. ![]() If the number of amps goes up, then current flowing through the device per second also goes up. When we talk about amperes (or amps), we are talking about how much electricity “flows” per second. For example, a device that works on 12 volts obviously needs a battery that also supplies 12V. 12, 24, or 36 volts) and a device always works at a certain voltage. A battery always has a fixed voltage (e.g. With a 12V device, 12 volts are always “given” from the battery. By a circuit we mean, for example, an electronic device. The number of volts is the amount of energy given to an electronic circuit. Below we will try to explain what it all means. Alternatively, if you are looking to upgrade your current UPS, refer to our UPS Upgrade Selector and don’t forget to utilize our Trade-UPS Program which allows you to receive up to a 25% discount on the purchase of a new APC by Schneider Electric UPS when you trade in your old model, regardless of the manufacturer.įor further discussion regarding the differences between watts and VA please refer to White Paper 15, Watts and Volt Amps: Powerful Confusion.We understand that all this terminology can be a bit confusing at times but once you know how it works it is quite simple. Please refer to our UPS Selector for help properly sizing a UPS. The difference between 0.8 or 0.9 power factors and a unity power factor (1.0) may not sound like much – but when you take into account the fact that the extra available wattage can be used to support additional loads and extend runtimes it is easy to see how the next generation of Smart-UPS On-Line will increase your availability while saving you money. Smaller models of the next generation of Smart-UPS On-Line have a 0.9 power factor or higher, and all are Energy Star™ qualified regardless of VA. Models 6kVA (6000 VA) and higher have a unity power factor – which means VA translates to an equal amount of watts (i.e. This power factor is what really matters when sizing a UPS for your specific requirements.ĪPC™ by Schneider Electric’s™ latest generation of Smart-UPS™ On-Line now delivers innovative features to help you make the most of your energy™. The ratio of the watts to VA is called the “Power Factor” and is expressed either as a number (i.e. What you really need to know is that for electronics such as computers and UPSs, watt and VA ratings can differ significantly with the VA rating always being equal to or larger than the watt rating. The watt rating determines the actual power purchased from the utility company and the heat loading generated by the equipment and the VA rating is used for sizing wiring and circuit breakers. Watts is the real power drawn by the equipment, while volt-amps are called the “apparent power” and are the product of the voltage applied to the equipment times the current drawn by the equipment. Most of us have heard of watts before – and have some understanding that each piece of equipment has a certain amount of watts it draws to operate, but how exactly does that relate to a UPS? And what does VA stand for anyway? What does VA stand for anyway?Įlectronics have both maximum watt ratings and maximum VA (volt-ampere) ratings and neither the watt nor the VA rating of a UPS may be exceeded by the attached equipment (load). So have you ever decided to research some UPSs to see which is the right fit for you, only to be left asking yourself, “Watts? VA? Huh?” Between the increasingly fragile power grid, the escalating power consumption of IT equipment and the constantly increasing importance of our network, it isn’t difficult to see the value a UPS (uninterruptible power supply) has to not only a business but a home.
