What transformer is used for neon signs?
What transformer is used for neon signs?
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.
How do you size a neon 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?
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.
How do neon transformers 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.
Are Neon Signs High Voltage?
Neon tubes require a high voltage at a low current to operate. This power is supplied by a specialized transformer. Secondary voltages typically range from 1,000 to 15,000 volts, and secondary currents range from 20 to 60 milliamps (and higher, for large diameter “cold cathode” tubing).
How do you test a neon transformer?
Look at the neon sign that is plugged into the transformer. Look for flickering of the light (other than the initial flickering during the warm-up phase of the neon gas). If the light is flickering, then the current supplied by the transformer could be erratic or the neon sign itself could be worn out.
What voltage does neon light require?
Neon lamps are recommended for 110 volt AC, 220 volt AC, and DC applications in excess of 90 volts. The lamps are available in miniature and sub-miniature sizes. A neon lamp is constructed by mounting two electrodes within a small glass envelope.
How long does a neon bulb last?
between eight and 15 years
Most neon signs are expected to last between eight and 15 years, although many continue to function for much longer than that. Leaving a sign switched on for prolonged periods can shorten its lifespan, and leave it at risk of overheating or sustaining damage from electrical surges.
How long do LED neon signs last?
The average life expectancy (in hours) for a neon glass tube is 10,000. LED neon flex lights, on the other hand, offer up to 30,000 or more hours of light.
Do neon signs use a lot of power?
A red neon light’s typical energy consumption is at 3 1/2 to 4 watts per foot. 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.
Are neon signs AC or DC?
A neon light actually works using either AC (alternating current) or DC (direct current), but if DC current is used, the glow is only seen around one electrode. AC current is used for most neon lights you see.

Can you use a regular dimmer on a neon sign?
Dimmable neon transformers have specialized circuitry and are controlled by a knob usually located near the power switch. These transformers should not be paired with regular dimmers. Using a regular dimmer can damage the sign or create a fire hazard.
