- Robust Construction: Virtually indestructible circuitry that is open and short circuit protected, ensuring durability and resilience.
- High Frequency Output: Operates at a high frequency of 25 to 35 kHz, allowing easy conversion to high-voltage DC sources using voltage multiplier stacks.
- Dual Functionality: Direct high-frequency output powers plasma and gas discharge (neon) display tubes with ease.
- Efficient Design: Circuit design is virtually 99% efficient, making it ideal for solar and battery power applications where every watt counts.
- Compact Dimensions: Open frame with a potted transformer measuring 5 x 1-1/4″, providing a space-efficient solution.
- Dimming Control: Includes 12″ input and output leads with dimming control, drawing 1.5 amps when operated at full output.
- Easy Operation: Simple board level layout measuring 5 x 2″, ensuring user-friendly operation.
- Versatile Compatibility: Suitable for field use, running from any 12V battery with at least 1.5A output. Also compatible with our 12DC/1.5 wall adapter.
- Low Power Consumption: Dimming control reduces current to less than 0.1 amps, allowing operation from solar cells or batteries.
- Ideal for Small Displays: Perfect for smaller displays, suitable for plug-in only.
Technical Specifications:
- Input: 12-14 VDC, 1000 mA (14DC/1G adapter, sold separately if needed).
- Output: 7kV open circuit at 10 mA short circuit.
- Compact Design: Open frame with potted transformer measuring 5 x 1-1/4″.
- Extended Reach: Lights over 12 feet of 12 mm tubing from a single electrode.
- Versatile Applications: Excellent for small plasma globes, gas-filled figurines, “luminglass” plates, and other small gas-filled objects.
- Power Supply: Runs natively from 12VDC; 14DC/1G wall adapter available for 110VAC wall power.
