12000 volt neon sign transformer

A neon-sign transformer (NST) is a transformer made for the purpose of powering a neon sign. They convert line voltage from the 120-347 V up to high voltages, in the range of 2 to 15 kV. These transformers supply between 18-30 mA; 60 mA on special order.

How do you size a neon sign transformer?

To determine the required transformer voltage, multiply the operating voltage by 1.5 for argon/mercury and 1.8 for neon. Repeat this procedure for each tube in the sign, and tally the total for all tubes you want to put on one secondary circuit.

Do neon signs need a transformer?

Neon signs play an important role for your business. Providing glitz and glamor, aesthetics and color; these signs must have a Neon Sign Transformer (power supply). Transformers are used to convert raw voltage into power for your Neon Sign.

What voltage do neon signs use?

Striking Voltage: The voltage at which the neon lamp ignites is usually between 45 and 65VAC for standard brightness types and between 70 and 95VAC for high brightness types.

How long do neon transformers last?

You can expect your neon sign transformer to last up to eight to 15 years. The numbers solely depend on how much and how you use the signages. Those signs are up indoors, away from direct heat, can last longer than those that face the weather every day.

Do neon signs use AC or DC?

A neon light works using either AC or DC current. However, if DC current is used, the glow can only be seen around one electrode. That is the reason why most of the neon signs use AC current. When an electric current is applied to the terminals, there is enough energy to remove an outer electron from the neon atoms.

How do I calculate what transformer I need?

To determine the required transformer VA, multiply the secondary voltage by the required amperes: For example, VA=Volts x Amperes or 28V x 1.2 amperes = 33.6 VA. To determine the maximum transformer current, divide the transformer VA by transformer secondary voltage.

How do I choose a transformer size?

How to Size a Transformer

Transformer size is determined by the kVA of the load.
Load voltage, or secondary voltage, is the voltage needed to operate the load.
Line voltage, or primary voltage, is the voltage from the source.
Single-Phase has two lines of AC power.

How much should I oversize a transformer?

In fact, recommended loading for economic sizing of a transformer is typically around 75% of nameplate (35% load, if constant, means the transformer is oversized and wasting core loss as well as well as higher purchase price.)

Do neon signs use a lot of power?

If you continuously run a sign for 12 hours, a foot of red neon sign would typically use about 15.33 to 17.52-kilowatt-hours of electricity per year while a fluorescent model will take up 50 percent more than that.

How much power does a neon light take?

How much electricity do they use? Neon signs are quite energy-efficient and consume far less power than you might think given how brightly they glow. Most modern signs come equipped with a 240v transformer and use about the same amount of electricity as a single domestic light bulb (60W–100W).

Why do neon lights need high voltage?

The voltage across a discharge tube will accelerate a free electron up to some maximum kinetic energy. The voltage must be large enough so that this energy is more than that required to "ionize" the atom.

Can you leave neon on all the time?

The answer is yes. Although it may seem counter-intuitive, leaving your neon sign on 24/7 will make it last longer. The electricity cost will be minimal.

Does neon ever burn out?

Neon signs can burn out, this is where all or part of the sign will stop glowing. There are various causes of this burnout. Bad transformers:- Neon signs glass tubes are illuminated by the use of transformers. If the transformer fails, the sign will not light up.

Is neon making a comeback?

Neon is making a comeback. Here's why. A revival of fantastic, flickering signs is illuminating roadside America, from legendary Route 66 to the Vegas strip. Around 250 vintage signs fill the outdoor “boneyard” at the Neon Museum Las Vegas.

How do neon signs get power?

Neon tubes or lamps can be powered by either AC or DC power sources. AC-powered neon lights use alternating current at 120 volts for operation and require an external transformer that reduces the voltage to 12 volts.

Which is better LED or neon signs?

Energy savings - Here an LED sign is the clear choice as it can be up to 10x more energy efficient than the same sign made from glass neon tubes. Versatility - LED lights come in a much wider range of colors and can be bent much more tightly giving you better options as regards shapes and styles of signage.

How does a neon transformer work?

Neon signs use neon gas that is inert in nature. These signs are made up of tubes that are filled with this gas. This tube is supplied with high voltage obtained from the transformers. The high voltage supplied by them increases the kinetic energy of electrons in the neon atom.

How many amps can a 1000va transformer handle?

A transformer with a 1.0 kVA rating is the same as a transformer with a 1,000 VA rating and can handle 100 volts at 10 amps of current.

What is the difference between K 4 and K 13 rated transformers?

The K4 Transformer is used in applications in which a major portion of the load is non-linear devices, and the 24 hour average load duty cycle is 80% or higher. The K13 rated Transformer is used where the majority of the load is non-linear, and the 24 hour average load duty cycle is 95% or higher.
