To answer this question a voltage is needed. I = 20/E.
<<>>
Each device powered by the transformer will have a rating of draw also in VA. So many for a t-stat, so many for zone valve or damper etc... add em up, make sure transformer is over and you re good. 20 VA is not very big. door bell Transformers are around that size. most hvac systems need 30, 50, 70 or more VA.

What is the ampere range value of transformer?
This typically has to do with how many amps you can safely pull from the secondary of the transformer.
How many amps can a 0.50 kva transformer give 277v input 120v output?
To determine the output current in amps for a 0.50 kVA transformer with a 277V input and 120V output, you can use the formula: Power (kVA) = Voltage (V) × Current (A) / 1000. For the output at 120V, the current would be calculated as follows: 0.50 kVA = 120V × Current (A) / 1000, which gives Current = (0.50 × 1000) / 120 ≈ 4.17 amps. Thus, the transformer can provide approximately 4.17 amps at the 120V output.
How many amps will a 10 kva transformer handle?
It depends on how many amps it was designed for. A 12.5kV/600v 10kVA 3 phase transformer can handle ~.5 amps on the primary and ~10A on the secondary. A 600/120V 10kVA 3 phase transformer can handle ~10A on the primary and ~50 on the secondary.
7200 volt 25kw transformer how many amps at 240 single phase?
The formula you are looking for is I = W/E. Amps = Watts/Volts.
How many amps does a 5v transformer draw?
There are actually three pieces to this puzzle - resistance. And you're missing that one.
How many amps does a 55kva transformer can provide?
To determine the amperage a 55 kVA transformer can provide, you can use the formula: Amps = kVA × 1000 / Voltage. For example, at a standard voltage of 400V, a 55 kVA transformer can provide approximately 79 amps (55,000 / 400 = 137.5). The actual amperage will vary depending on the specific voltage used in the application.
How many amps can a 250 va transformer carry?
A transformer is a power source. It will provide voltage to a device. Find the voltage rating on the device, say 24V. 250/24 = ~10A.
How many amps does a 0.05 transformer provide?
You have not provide enough information. You don't explain what 0.05 references. You need to know the secondary voltage and resistance to calculate current.
What is the ampere range value of transformer?
This typically has to do with how many amps you can safely pull from the secondary of the transformer.
How many amps will a 0.25 kilo volt amp transformer at 120 volts put out?
2.083 amps
How many amps can you get from a 500Kva transformer?
The amps you can get from a 500 kVA transformer would depend on the voltage of the transformer's output. To calculate amperage, you can use the formula: Amps = Power (kVA) / Voltage. For example, if the output voltage is 480V, you would get approximately 1041 amps (500 kVA / 480V).
Unanswered questions-how many amps for a 500KVA transformer.?
To determine the amps for a 500 kVA transformer, you can use the formula: Amps = kVA × 1000 / (Voltage). For example, at a standard voltage of 480V, the calculation would be 500,000 VA / 480V, which equals approximately 1041.67 amps. The specific current will vary based on the voltage level used with the transformer.
How many amps can a 0.50 kva transformer give 277v input 120v output?
To determine the output current in amps for a 0.50 kVA transformer with a 277V input and 120V output, you can use the formula: Power (kVA) = Voltage (V) × Current (A) / 1000. For the output at 120V, the current would be calculated as follows: 0.50 kVA = 120V × Current (A) / 1000, which gives Current = (0.50 × 1000) / 120 ≈ 4.17 amps. Thus, the transformer can provide approximately 4.17 amps at the 120V output.
How many amps can a volt transformer with a A volt secondary carry?
The number of amps a transformer can carry on its secondary side depends on its power rating (in watts or VA) and the voltage of the secondary winding. You can calculate the current (in amps) using the formula: Amps = Watts / Volts. For example, if you have a 1000 VA transformer with a 10V secondary, it can carry 100 amps (1000 VA / 10V = 100A). Always ensure the transformer is rated for the desired load to avoid overheating or damage.
How many amps does a 600 watt low voltage transformer box pull?
The transformer itself does not pull current. Whatever you connect to the transformer pulls current. Whatever the output voltage of the transformer is, divide that into 600 and you get maximum current possible without burning up the transformer. At 24V that's 25 amps.
How many amps will a 10 kva transformer handle?
It depends on how many amps it was designed for. A 12.5kV/600v 10kVA 3 phase transformer can handle ~.5 amps on the primary and ~10A on the secondary. A 600/120V 10kVA 3 phase transformer can handle ~10A on the primary and ~50 on the secondary.
How many amps will a 37.5 KVA transformer carry?
It depends on the rated voltage of its secondary.
