Connection diagram for QINIZX NIXIE-HV250V Boost Module
Figure 1: Connection diagram for the 3845 Boost Module. Shows input (VCC 10V-24V, SHDN, GND) and output (90V-250V, GND) terminals, and the output adjust potentiometer.

The diagram illustrates the input and output terminals. The input voltage (VCC) should be between 10V and 24V DC. The output voltage is adjustable from 90V to 250V DC.

Input Connections (P1)

  • 12V (VCC): Connect your DC input power supply positive terminal (10V-24V).
  • GND: Connect your DC input power supply negative (ground) terminal.
  • SHDN: This is the shutdown control pin.
    • To disable the booster board, connect this pin to a high logic level (e.g., from a microcontroller).
    • If not using the shutdown function, leave this pin vacant or connect it to GND to keep the module operational.

Output Connections (P2)

  • +: Connect the positive terminal of your high-voltage load (e.g., Nixie tube anode).
  • -: Connect the negative terminal (ground) of your high-voltagbeban e.

Keluaran Voltage Pelarasan

Keluaran voltage is adjusted using the onboard potentiometer (blue square component with a screw slot). Use a small screwdriver to carefully turn the potentiometer clockwise to increase the output voltage, and counter-clockwise to decrease it. It is recommended to adjust the voltage while monitoring the output with a high-voltage multimeter.

Arahan Operasi

  1. Persediaan Awal: Before applying power, double-check all input and output connections according to the "Setup and Connections" section. Ensure the SHDN pin is configured as desired (vacant/GND for operation, high for shutdown).
  2. Apply Input Power: Connect your 10V-24V DC power supply to the input terminals (12V and GND).
  3. Laraskan Output Voltage: With power applied and a high-voltage multimeter connected to the output, carefully adjust the potentiometer to achieve the desired output voltage (90V-250V). Start with a lower voltage and gradually increase it.
  4. Sambungkan Beban: Sebaik sahaja output yang dikehendaki voltage is set, disconnect the input power, connect your high-voltage load (e.g., Nixie tubes), and then reapply input power.
  5. Pemantauan: Periodically monitor the module's temperature during operation. While designed for low heat, excessive load or poor ventilation can cause overheating.

Penyelenggaraan

The QINIZX NIXIE-HV250V module is designed for reliable operation with minimal maintenance. Follow these guidelines:

  • Jaga kebersihan: Ensure the module is free from dust, dirt, and moisture. Use a soft, dry brush or compressed air for cleaning.
  • Pengudaraan: Provide adequate ventilation around the module, especially if enclosed, to prevent heat buildup.
  • Periksa Sambungan: Periodically check all wiring connections for tightness and integrity.
  • Elakkan Beban berlebihan: Do not exceed the specified output current limits, as this can lead to reduced efficiency, overheating, and potential damage.
