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.
|
Charges capacitors to rated voltage and allows to set for determining excessive internal leakage.
Small lightweight unit measuring 5 ½ x 2 Ό x 1 ½ converts 12 vdc to over 20kv 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.

OTHERWISE REQUIRES OUR
Handy electronic circuit charges up electrolytic capacitors from 100 to 800 volts. Recommended capacities are between 100 to 5,000 ufd. 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 40 (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. DANGER A SERIOUS DEADLY SHOCK HAZARD EXISTS WHEN USING WITH HIGH ENERGY CAPACITORS ABOVE 50 JOULES. CHARGE800V - Assembled ready to use, charges up to 800 volts at 25 joule/sec .......$59.95 |
