high pressure sodium ballast output voltage use high pressures of sodium, in an excited state, to generate light. A magnetic ballast, in series with an AC current voltage source, supplies the lamp with a near-constant stream of current.

A very hard number to pin down as the job of the ballast is to adjust the voltage to keep the current constant. Because of this often the numbers given will be the open circuit voltages and they greatly depend on the type and size of lamp. This Video explains how the Ballast Resistor Works.For additional How-to Tutorials Visit our Website: http://www.howstuffinmycarworks.com If your ballasts all tested well, you will need to test the low voltage side of the transformer. Start by removing the nuts from the black and white wire that come from the power feed side of the ballast. Touch the probes of your volt-ohm meter to the black and white wires. If your ballast is properly functioning, it will show a continuous Generally, the voltage of the battery is 6V or 12V or 24 V. In an automobile there are two types of Battery use widely, one is lead-acid battery and another one is the alkaline battery. Although there are Zinc Acid Battery and Lithium-Ion Battery is used in modern vehicles.

However, Accel recommends that the OEM ballast be retained. I have generally sided with Dyna on this point. Modern high performance coils are designed to handle nominal 12V battery voltage (and cruise voltage of around 14.5V) without issue, so I think Accel’s advice is overly conservative. Fluorescent lamps use a ballast which transforms line voltage to a voltage to start up and operate the lamp(s). Newer fluorescent ballasts are usually rated for both 120 volts and 277 volts .

An HID ballast is a boosting transformer that converts battery voltage into the approximately 75 to 110 volts needed to maintain the arc. The ballast is designed to detect bulb shut down. If the bulb turns off, the ballast will automatically restart the bulb within ½ second.

I was thinking if put resistor in series with relay coil i could lower current so relay would barely work on 12v but when it drops to 10v voltage after resistor w Some Harley owners like to fix their own bikes, thereby saving both money and riding time. A Harley Davidson can experience electrical problems at any time, but there can be a wait for a service appointment at some repair shops. The most co I have an old tractor with a 6v system and i would like to put a 12v battery in it and for a couple other projects i would also like to know how to do this. thanks ron fancher I have an old tractor with a 6v system and i would like to put The Kobold BB200/C DC Ballast is for the DW200 HMI fixture.

Now filtered DC voltage is fed to the high-frequency oscillation stage where oscillation is typically square wave and frequency range are from 20 kHz to 80 kHz. frenchelectrican said: I have see that high a voltage level on output leads however if you did check the ballast label sometime they will list the OCV as well so you will find it. The last 8 footer T-8's they did have 650 OCV so it kinda expected to see that high. Merci, Once the engine fires, the alternator (stator actually) comes online and battery voltage is regulated to approximately 14.5 Volts at normal cruise RPMs (voltage is less at lower RPMs). Without intervention, the coils which are optimized for 7-9 V would now be seeing the primary input voltage of 14+ volts.

Whenever there is a need for battery-powered lighting, like for camping, solar If this happens while the current in the ballast was near a peak, a high voltage 

In order to start a fluorescent bulb, an arc between two electrodes in the lamp must be produced. 2.2. If the voltage drops to approx 5 volts or 6 volts, there is a ballast resister or resister wire. 2.2.1 Use a 1.5Ω ballast coil. 2.3 If the voltage drops to approx 8v to 9v, there is a ballast resister and possibly a non-ballast 3Ω coil. 2.3.1 This is not a good combination and will lead to a weak spark and poor running. Ballast that is working will read a continuous circuit.

Is that correct? In this combination, Dyna recommends NO BALLAST. However, Accel recommends that the OEM ballast be retained. I have generally sided with Dyna on this point.
