Transform any setting into a captivating and electrifying spectacle with this simple yet impressive high-voltage demonstration kit. It consists of two precisely bent stainless steel rods and a secure mounting base, designed for seamless integration with one of our half-bridge amplifiers (when paired with a flyback transformer) or any other high-voltage power source. Witness the mesmerizing phenomenon as a high-voltage electric arc forms at the bottom of the rods, where the gap is narrowest, and gracefully climbs upward until it extinguishes, only to repeat the process.
Key Features:
- Simple and Elegant Design: Two carefully shaped stainless steel rods ensure consistent and smooth arcing.
- Secure and Durable Base: Sturdy base allows safe and stable operation during demonstrations.
- Removable Rods for Easy Transportation: The stainless steel rods can be easily detached from the base, making it convenient to transport and store the kit.
- Spectacular Visual Show: The climbing electric arc is perfect for engaging and impressing spectators.
Performance Tips: For optimal results, use burst mode on your function generator. Configure it to 3–5 cycles with a burst repetition rate of 300–1000 μs at the resonance frequency of the transformer. This prevents the electric arc from getting 'stuck' on the rods, ensuring it moves smoothly and continuously upward.
In the video shown on this page, we used our 350V Half-Bridge amplifier running at around 220V input together with the 25kV AC Flyback Transformer. This is why the arc appears so bright and stable in the demonstration. Please note that using the DC Flyback Transformer for this setup is not recommended, as it does not perform well in this application. However, if you wish to use DC, our High Voltage DC Power Supplies (30kV and above) are compatible with the Jacob’s Ladder kit. Keep in mind that when using HV DC power supplies, you cannot utilize burst mode like you can with a function generator, so you may experience that the arc tends to stick more to the rods instead of climbing as smoothly as with the Half-Bridge setup.
Important Safety Information:
- The stainless steel rods can become extremely hot after operation. Allow sufficient cooling time between runs to prevent damage or injury.
- Always operate the kit in a safe environment, away from flammable materials and with proper high-voltage safety precautions.
