Is it safe to use a step down transformer rated 16 Volts and 40 VAC in place of required transformer rated 24 Volts and 40 VAC?
Transformers that operate specific devices should be matched to the specific voltage on the device that the manufacturer specifies.
Can you use a 9volt 500 milliamp transformer for a door bell?
The key is the door bell specification. They typically run on a 24 VAC transformer. You can certainly hook it up and try it with 9 volts, but it probably won't work as intended. 24 Volt transformers are relatively cheap.
What would the input current be for a 275 kva transformer with 2 phase of a 480 vac in and 120 vac at 20 amp output?

A new 120 vac 24 vac 60 watt transformer for a 24 volt bulb in a lawn lampost gets too hot to handle after a few hours?
Low voltage lighting is famous for getting over heated. With the lower voltage more current flows to get the equivalent wattage output you would find in a 120 VAC circuit. For a similar wattage bulb in a 24 VAC system you draw 5 times the current and higher currents generate more heat. The most common problems in low-voltage lighting systems are poor wire connections, too many lights on one transformer and wire that is too small for the load. It is usually recommended to re-tighten all connections in a low voltage system after a period of time.
You have two devices that are rated at 230 VAC single ph and your supply voltage is 480 VAC 3 ph you need a 480 VAC 3 phase to 230 VAC three phase xfrmer how do you calculate the xfrmer size?
The transformer size is calculated by using the load current that is required on the secondary side of the transformer. This secondary current is multiplied by the secondary voltage times 1.73. This total is then divided by 1000 to give you KVA. KVA = I x E x 1.73/1000.
How do you convert 24 vac to 5 vac?
You can convert 24 vac to 5 vac with a transformer with windings in the turns ratio of 24 to 5.

How can you reduce the voltage from a 220volt ac input 24volt dc output to 220volt ac input 12 volt dc output?
To change from 120 V AC to 24 V AC, just connect it up to an appropriate transformer. To convert 120 V AC to 24 V DC, you'd need a transformer followed by a full-wave rectifier and filter capacitors.
What would be the power in the secondary of a transformer that has a voltage of 48 vac and a current of 2.2 a?
48*2.2 = 105.6VA

How can you increase 4.5v to 5.5v?
To increase a 4.5 VAC supply to 5.5 VAC, use a transformer. To increase a 4.5 VDC supply to 5.5 VDC, you'd need a boost converter.
Can you get 220 vac 50hz from 380 vac 50hz?
I know that a company named TEMco makes a 380v to 120/208 transformer. You can try contacting them for your specific application I will attach their website for you.
What do you mean by no load of transformer?
Transformers voltage ratings are typically at full load. For instance, A 24 VAC, 10A transformer will have a terminal voltage of 24 when it is feeding 10 amps to a load. Since the transformer windings have some resistance, the transformer designer has to wind the transformer to put out more than 24 volts, since some of the voltage will be lost, dropped across the resistance of the secondary windings. But, according to Ohm's law, the voltage dropped across a resistance is proportional to the current (E=IR). If we take away the 10A load, there is no current, and therefore no winding voltage drop! The excess voltage the designer built in now appears at the terminals. This is the no-load voltage. In my example above, when we remove the 10A load, the output voltage of the transformer might rise to 26.4V. We would say the no-load voltage of that transformer is 26.4V The ratio of full-load voltage to no-load voltage is called the transformer's "regulation factor". It is calculated as: (no-load voltage - full-load voltage) / full-load voltage * 100. Ours is: ((26.4 - 24) / 24) * 100 = 10%.
Do you have a drawing for zenith pro-logic amp z712b that you can copy or consult for working voltages of its small transformer?
The small transformer (at the back of the enclosure) has a single centre-tapped secondary. The voltage across the entire secondary is 28.8 VAC, or 14.4 VAC across each half, as measured with a 3.5 digit DMM on my working sample of this receiver. The primary appears to be configurable for either 120 or 240 VAC.
