That will depend on the UPS specifications (e.g. output VA rating, efficiency) as well as the load's reactance.
There are UPSs with output VA ratings from as low as 100 VA to several hundreds of thousands of VA (this is more than 3 orders of magnitude in equivalent wattage). The higher VA rated UPSs must by the electrical code be wired directly (they cannot be plugged in and they weigh several tons so they can't be moved either) by a licenced electrician.
The more efficient a UPS is, the closer the input watts needed will be to the output VA rating, a less efficient UPS will need more watts.
The only way you can get a reasonable estimate of the answer to this question is to read the specifications in the manual for the specific UPS you are interested in or are already using.
A 850 VA UPS typically uses around 510 watts when operating at full load. This is because the power factor of most modern UPS systems is around 0.6.
To convert kilowatt-hours (kWh) to watts, you need to multiply by 1000. So, 1209 kWh is equal to 1209,000 watts.
A typical block heater for a car engine would be around 400-1500 watts, depending on the size and efficiency of the heater. This kind of heater is used to keep the engine warm in cold weather for easier start-ups.
15.
To calculate the voltage from watts, you need to know the current (amps) as well. The formula is: Volts = Watts / Amps. Without knowing the current, it's not possible to determine the voltage from watts alone.
A 850 VA UPS typically uses around 510 watts when operating at full load. This is because the power factor of most modern UPS systems is around 0.6.
It is expressed in Volt-Amperes not Watts.
UPS batteries are typically rated at how many ampere hrs they can supply. IF your 20 Watt device is supplied by 120V then it draws 1/6 amps. (Watts = Amps * Volts for a resistive load). If your UPS were rated for 1 A Hr you could power your device for 6 hours.
UPS power is not specified in watts.However VA is the equivalent of watts, assuming no phaseshift in the load.
770 watts.
Amps, volts and watts are interrelated, but you need to do a little math. Amps * Volts = Watts
26watts
1HP = 746 watts 15 HP = 11190 watts = 11.19 kW You would need a generator of at least 13kW. UPS Distributor for 15 Years.
Ignition 30 watts, fans 30 watts, driving lights 30 watts, headlights 100 watts. Total about 200 watts.
it depends on how many you can do
You need amps
