Safe High Voltage:
A typical negative ion generator is actually a 10,000-volt DC power supply. Even better, since the high-voltage terminal must be safely touched by the users, ion generators are SAFE, current-limited, high- voltage power supplies. (This, as opposed to OZONE GENERATORS, which often are a quartz tube with mercury vapor. Only 800VAC as a tube-driver, no DC high volts.)
SAFETY - ION GENERATORS MUST BE SAFE IN ORDER TO BE SOLD IN THE UNITED
STATES. CHECK FOR SAFETY WARNINGS ON YOUR ION GENERATOR BEFORE USING
IT IN THIS APPLICATION. ALSO, NOTE THAT THIS TYPE OF GENERATOR CAN
DELIVER SMALL "STATIC ELECTRIC" SHOCKS. THERE ARE OTHER HAZARDS
YOU SHOULD KNOW ABOUT:
1. NEVER REMOVE THE CASE OF AN ION GENERATOR OR STICK ANY OBJECT
THROUGH SLOTS IN THE CASE, BECAUSE THE 120V POWER CONNECTIONS WITHIN
THE DEVICE CAN ELECTROCUTE YOU.
2. DON'T MESS WITH IONIZING FAN-TYPE APPLIANCES. THEIR HIGH VOLTAGE
CONNECTIONS ARE BURIED DOWN INSIDE THE CASE, AND ARE DANGEROUS AND
NOT INTENDED TO BE TOUCHED WITH FINGERS. STAY WITH SMALL, SAFE,
DESKTOP/ TABLETOP ION GENERATORS.
3. NEVER PLAY WITH LEYDEN JARS OR HIGH- VOLTAGE CAPACITORS LARGER THAN
50 PICOFARADS. WHEN CHARGED UP BY AN ION GENERATOR (OR ANY
OTHER HIGH- VOLTAGE SOURCE,) THEY CAN ELECTROCUTE YOU.
I found a $5 ion generator at a garage sale. It works really well as an
electrostatic power supply for the
and other "static
electricity" experiments. I estimate the output voltage to be
between 10,000 and 15,000 volts. This is well into the "static
electricity" voltage range. I measured the output current and found 5
uA (microamperes). 5uA is totally safe, it is smaller than the current
obtained from touching a flashlight battery with damp fingers.
