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. 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.
How much voltage does a neon sign need?
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.
Can a neon sign transformer be repaired?
Usually, a professional can take one look at the sign and figure out whether you have a voltage problem or if something is wrong with the transformer. You can also do some repairs yourself, if you are confident.
How many watts is a neon transformer?
Wire Wound Transformer: 6kV 25mA running at 95 watts.
Are neon transformers AC or DC?
The two neon transformers, which require 230 V AC input are connected to the medium voltage GND at one side and the other side is left open, and a plug for that is available at the outside of the box. By means of external wiring, it can be connected to one of the 70, 100, 120 or 140 V AC outputs.
What causes a neon sign to flicker?
Check the voltage supply to the light and look for any loose connections. Low power will cause a blinking or flickering neon light. You may need to use a step-up transformer if the voltage to the light is not high enough. Use a multimeter to check the voltage on all electrical spots.
Do neon signs draw a lot of power?
LED neon signs are highly efficient for energy consumption Statistically, one foot of the conventional neon light absorbs about 20 watts of electricity per hour. In contrast, the same length and thickness of the LED neon tube can be consumed as low as 1.2 watts for the same duration.
How many amps does a neon light draw?
The average neon sign only consumes about . 8 amps ( 8 tenths of an amp). This equates to about 96 watts (about equal to a single light bulb).
How do you power a neon tube?
Put the caps back on the ends of the neon tubes with the power wires underneath. Plug the power cord (the one with the socket plug on it) into a nearby wall outlet. Flip the power switch on the neon transformer and check to make sure the neon tube lights up.
