The safest way to determine what you can plug into your UPS is to take the total number of amps* used by the equipment you wish to attach and multiply by 120VA. For example, an average computer, modem and monitor uses approximately 3 amps (3 x 120VA = 360VA). So, choose a UPS product that provides at least 360VA amp protection. In this example the SYC650BB would be fine. Read in more detail about sizing... for back-up power, small units like the SYC650BB will run for about 12-20 minutes.

There is no standard answer. There are UPS solutions available to support almost any application typically from five minutes to sixty minutes, the solution just depends on the application needs. Ideally, sufficient run time should be planned to allow the stopping of any running operations and safely shutting down the system.

Using thicker power and ground cables will allow your amplifier to draw the juice it needs from the battery more easily. You'll find all the power and ground cable you need available in our online Installation Store. Before you can decide on the appropriate gauge wire for your installation needs, you need to figure out the current demand of your system. To do that, you must ascertain the approximate current draw (in amperes) of your amplifier (or amplifiers).

The main purpose of your power supply is to run your trains. To run your train your power supply must supply energy for your locomotive, smoke unit, sound system , and any lighted cars. You may also need power for accessories like switches, street lights, building and house lighting or any other accessories. Your TOTAL POWER REQUIREMENTS depends upon the number of locomotives or motors, and ALL OTHER items that require electricity. The length of the track is not a factor.

That depends on how big a UPS do you have and what kind of equipment it protects. For most typical computer workstations, one might have a UPS that was rated to keep the machine alive through a 15 minute power loss. If it is important for a machine to survive hours without power, one should probably look at a more robust power backup solution that includes a generator and other components.

Yes. A UPS is NOT a TVSS! In fact it is necessary to provide TVSS protection for the UPS so it will not be damaged if there are transients present on the power system at the input to the UPS. In addition, all of the other equipment in your facility that is not connected to the UPS is unprotected and susceptible to transients and must be protected. No. A transformer does not stop high frequency transients like lightning. A typical lightning transient is several hundred micro-seconds in duration.

Sizing an inverter is nothing but simple math. A TV may require 150 watts and the VCR you want to add with it may require only 100 watts. Just simply add the wattage requirement for all the appliances that will run at the same time. The answer is 250 watts for both the TV and VCR to run. However, it is recommended to always go slightly bigger (25%). This will ensure that the inverter will power all appliances safely. For more information, visit our Inverter Sizing page.

Ans: Note down the number of units (KWH) you are using every day during a month when you use electricity the most. This value can help us size the solar power system you need. You can measure the units from the electricity meter in your home.

Electrical noise is truly an invisible problem since the damage it does may not cause your system to fail immediately. This unseen damage frequently causes "soft" failures, such as those unexplainable errors in printing, system lock-up or inaccurate test results. Ultimately, the cumulative effect of these problems will show up as hard failures. And that means your system stops working and requires repair.

Having a power conditioner on site does not automatically mean that your site will be trouble free from power quality issues. While having it should help reduce the chances there are still several issues that need to be documented: If the customer bought the conditioner from the manufacturer than the manufacturer assumes the liability for all power issues (at least in the customer's mind) and the site may have issues that the unit is not designed to fix.

Check your equipment’s power requirement (in VA). This can be easily calculated by referring to the back of your machine or hardware documentation. Consider the amount of back-up time you need. I.e. how long do you need for your equipment to go on functioning in a blackout so you can save and close your documents, for instance. This determines the capacity of your UPS. You can then choose a suitable UPS model catering to your power protection needs.

Your air conditioner furnace filters size is measured by the width x length x thickness in inches. For example, a pleated air filter that is 20x25x1 means 20 inches wide by 25 inches long by 1 inch thick. Most residential air conditioner furnace filters are 1” thick. The actual measurements of each air conditioner furnace filters are usually about half an inch less than the listed size.

To insure proper fitment on EVS knee braces, circumference measurements should be taken directly against the skin with your leg straight. Use a soft tape measure if at all possible. If you do not have access to a soft tape measure, use a piece of string, rope or yarn and then measure that with a regular ruler or tape measure. See Measuring chart for detailed sizing & directions.

Many people use the wrong size cable for their systems but working out what power cable you need is actually very simple. Add all the ratings together. ie total each amp so a 2x50wrms amp would be 100, then add the totals together. This gives you a number representing the current draw, in amps, of your system. Then match the current with the length of the cable in the following table to give you the correct size cable to use.

The right answer to this question depends upon which subwoofer you choose. You'll find a recommended power range (in continuous or RMS watts) listed in the specifications for each subwoofer on this website. The lower number is the absolute bare minimum amount of wattage you need to get acceptable results. Generally, more power is better because bass notes are power hungry.
