Transformers - High Voltage Current Limited


https://cdn1.bigcommerce.com/server800/64f33/content/Graphics/single-page-view.png

Information Unlimited has a remaining quantity of high voltage 60 Hz current limited transformers originally intended for large neon signs and other gas displays.

These transformers do not have the recently mandated GFI shut down circuitry and therefore are excellent for SCIENTIFIC APPLICATIONS, TESLA COILS, enclosed JACOB'S LADDERS, DC VOLTAGE MULTIPLIERS, GAS LASERS, PLASMA POWER SOURCES and many other specialty applications.

Transformers are easily parallel connected to double, triple, quadruple, etc., current for high power applications. However parallel connection of these units for increasing current can cause a deadly electrocution hazard. We also supply diodes and capacitors for conversion to DC direct current.

These Transformers may be used for DC applications. However it is not advised unless you are well experienced into handling high-voltage. You can download the data here for circuits and information.  See the PDF schematic here.

Regarding the 60 milliampere transformers:

Parallel connecting these units for increasing
current can cause a deadly electrocution hazard.


High Voltage 115 VAC 50/60Hz Transformers
for Tesla Coils, Capacitor Chargers, etc.
Current limited transformers are excellent for small Tesla coils up to 1 KW using stationary spark gaps. Multiple 115 vac 50/60 hz input units can have both primary and secondary windings connected in parallel for higher currents. Two identical 115 vac 50/60 hz input units can have primary windings connected in series for 220 volt operation.

Current-Limited HV Transformer at 30ma and 6KV
6kv 30ma transformer

6kv 30ma transformer
    

Centerpoint grounded secondary, current limited, encased unit with screw terminals. All connections are internal: remove cover to access, then push out a metal chad according to your location preference for running the input and output wires. This transformer is excellent for small table top Tesla coils. Dimensions: 10.75" (12.5" at feet) x 4" x 6.5” with a weight of 17lbs.

Please note: this transformer has the 6KV 30mA output required by our BTC30 tesla coil, but it is physically too tall to fit into the base area. The height of the BTC30 base area could be increased, however that is a modification you would need to undertake.

Shipping weight may exceed the website estimate -- we will contact you if any additional amount is required.
