Lower Cost Completely Manually-Operated Charger

Low Power Input, High Voltage Ceramic Capacitor Charger and Test Jig

These low powered devices may be used for battery or solar applications. They are short circuit proof and suitable for capacitor charging without a current limiting resistor. They may also be used as low power high voltage power supplies.

High Voltage DC Power Supply

Charges capacitors to rated voltage and allows the determination of excessive internal leakage. Charges up to 20KV.

Small lightweight unit measuring 5-½ x 2-¼ x 1-½” converts 12 vdc to over 30kv dc for charging capacitors or just supplying a potential. Can be used with 8 AA alkaline batteries that can produce >90,000 Joules (!), or just use our #12DC/.5 wall adapter for 115 vac operation. The charge rate is about 0.25 joule/sec. Higher voltage units available on request.

This device is best-suited for use with our ceramic capacitors or similar (taking care to not overcharge the smaller capacitors). For charging our photo flash and electrolytic capacitors (or similar), the CHARGE800V is better suited.

An external voltmeter is required to monitor charge. Small value capacitors must be charged by merely tapping the charge push button, as voltage value can be easily and quickly exceeded.

Manual Electrolytic Capacitor Charger

Low Power 800V 30mA Manually Programmable Charger for Electrolytic, Photo Flash and Other Equivalent Capacitors

Electrolytic Capacitor Charger

Handy electronic circuit charges up electrolytic capacitors from 100 to 800 volts. Recommended capacities are between 100 to 5,000 µfd. This equates out to over 3000 joules! (Note that the kinetic energy of a .30-06 is 750 joules.) Units are manually voltage controlled by an internal adjustment that presets a charge indicator lamp when the required voltage is reached. This feature helps prevents over charging and potentially dangerous explosions. Charging is current controlled by our unique circuitry. Input power can be C or D cell batteries or 12 vdc adapter for direct 115 vac power. Charging rate is over 25 (watt-sec) joules. Size is 5 x 4 x 2”

This device is best-suited for use with our photo flash and electrolytic capacitors. For charging our ceramic capacitors (or similar), the PBK50 is better suited.

An external voltmeter is suggested for charging to the desired voltage.

Latest technology to power rail guns and other electrokinetic devices currently being developed by the US Navy. Excellent for coil guns, these low inductance capacitors are also well-suited for numerous other uses like wire exploders, metals forming, materials testing, etc. Units measure 16”L x 12”W x 14”H and weigh 90 pounds with ground ring terminations. Capacitors may be ordered individually or in quantity, and will be strapped on pallets for shipping by truck. The original cost of these units are about 10 grand each. Our price is significantly less.

These capacitors are in excellent condition; our information and testing indicates that they were bought for a project, then kept in storage and never used. We have randomly sampled a few of our inventory, and all have tested to their full listed specs. If you don't mind a few paint chips and scratches, these capacitors will perform like new. They can be bought factory-fresh for $10,000 each, or get them from us for a fraction of the cost.

These high-performance units are the dream components of many high voltage, high energy experimenters. Capacitor is rated 959 µfd +/-10% at 11,000 volts, with a low 0.1uH inductance. A high energy density of over 26 Joules per cubic inch gives an energy storage of over 60,000 joules each!

These capacitors contain no P.C.B.s
