QINIZX NIXIE-HV250V DC-DC Boost Power Supply Module User Manual

Indledning

This manual provides detailed instructions for the safe and effective use of the QINIZX NIXIE-HV250V DC-DC Boost Power Supply Module. This module is designed to convert a low DC input voltage (10-24V) into a high DC output voltage (90-250V), making it suitable for applications such as Nixie tube clocks, vacuum tube circuits, and Magic Eye 6E2 level indicators.

Specifikationer

Note: The higher the output voltage, the lower the effective output power and efficiency.

Opsætning og forbindelser

Refer to the connection diagram and module images for proper wiring. Ensure power is disconnected before making any connections.

Tilslutningsdiagram

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-voltage belastning.

Udgang Voltage Justering

Output 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.

Betjeningsvejledning

1. Indledende opsætning: 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. Anvend indgangseffekt: Connect your 10V-24V DC power supply to the input terminals (12V and GND).
3. Juster 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. Tilslut belastning: Når det ønskede output voltage is set, disconnect the input power, connect your high-voltage load (e.g., Nixie tubes), and then reapply input power.
5. Overvågning: Periodically monitor the module's temperature during operation. While designed for low heat, excessive load or poor ventilation can cause overheating.

Opretholdelse

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

• Hold rent: Ensure the module is free from dust, dirt, and moisture. Use a soft, dry brush or compressed air for cleaning.
• Ventilation: Provide adequate ventilation around the module, especially if enclosed, to prevent heat buildup.
• Undersøg forbindelser: Kontroller regelmæssigt alle ledningsforbindelser for tæthed og integritet.
• Undgå overbelastning: Do not exceed the specified output current limits, as this can lead to reduced efficiency, overheating, and potential damage.
