thin line ballast for rv
The repair guy bailed out, said he thought the coil was bad. Basically, though there are only eight components, it seemed beyond him.
I have a working model that uses two 15 watt tubes and one that uses one 8 watt tube.
If you tell me what to measure with a...
code model dll 2n3055
Tanuki,
Thanks, I have taken the one unit to the electronics shop and asked him to throw in an NPN power transistor and see if it goes.
Truthfully, I can't remember if they fail when ON or, more likely, when TURNED ON for the millionth time.
I'd be interested if your...
lamp ballast power transistor
Tanuki,
Here's the best I can do:
1. What is the value of the snubber capacitor? .033 K 630
2. What is the resistance across the lamp heater pins? If we mean resistance across the pins of the lamp itself, when not connected to the circuit, it is between 20...
description of ballast transistor
You are absolutely awesome!
The unit I have been photographing is for one 15 watt tube, whereas the one in the patent is for two 8 watt tubes, but essentially the same.
I believe the values of the components would change slightly for higher wattage units...
how to you open a thin lite in a boat?
Tanuki,
This is great.
I am inserting the urls for a few close-ups of the caps. The values are
Big blue cap = 220 uF 35v
Big brown chicklet = .22k 250
Small brown chicklet = .01k 630
Grey ceramic resistor is marked = 5W 200 10%
The diodes are diodes...
pspice model ballast
Thanks for the help.
I will try both suggested transistors and see what works.
If anyone can sketch out the circuit and fill in parts values, that would be great.
I have closer images of the parts if needed.

15watt cfl inverter using d882
Dear oddbudman,
Well, after year, I am back on this project.
Here are photos of the circuit and the components.
and
The black wire is (+) and the white is (-). The two red wires go the pins at one end of the tube and the blues to the pins at the other...
thin-lite transistor
Folks,
I have a number of 12 VDC flourescent lighting fixtures on my boat, which my wife and I use as a home in the Dominican Republic, where we are humanitarian relief missionaries.
After many years, these are failing one after the other. The fault is the "transistor"...
