This is a high voltage power supply specifically designed to ignite and operate the Zeeman Discharge Tube (Mercury or Neon) efficiently and reliably. The unit provides the necessary high potential difference required to excite the gas within the Zeeman tube so that it emits its characteristic spectral lines. Crucially, this power supply is built with dual voltage input compatibility, allowing it to be safely connected to standard laboratory electrical lines of both $110 \text{ V}$ and $220 \text{ V}$ AC. It ensures a stable, consistent voltage output, which is essential for obtaining a bright, steady spectral emission necessary for precise measurements of the subtle Zeeman Effect line splitting when the tube is placed in a magnetic field.
Dual Voltage Compatibility: Features a robust input selector or internal circuit that allows operation on both $110 ext{ V}$ and $220 ext{ V}$ AC power grids, making it universally suitable for research and teaching labs.
Stable High Voltage: Provides a regulated and consistent high voltage DC or AC output, which is necessary for maintaining the tube plasma and preventing flicker or intensity variations.
Tube Protection: Incorporates safety mechanisms like current limiting circuitry to prevent premature damage or burn-out of the expensive, fragile Zeeman discharge tubes.
Optimized Output: The voltage and current output are carefully tuned to maximize the light intensity and spectral purity of the Mercury or Neon tubes.
Safe Operation: Housed in a durable, fully insulated enclosure with clearly marked, secure terminals to minimize electrical hazards during high voltage operation.
Input Voltage: Selectable or Auto-Sensing for $110 ext{ V}$ to $220 ext{ V}$ AC, $50$ to $60 ext{ Hz}$.
Output Voltage: High Voltage AC or DC output, typically $2 ext{ kV}$ to $5 ext{ kV}$ (depending on the tube requirement).
Regulation: Highly regulated output for stable spectral emission.
Protection: Overload and short circuit protection with integrated current limiting.
Terminals: High quality, insulated output terminals for secure connection to the discharge tube.
