Nixie Tube Boost Converter DC-DC 3.3V-20V TO 150-300V 160V 170V 200V High Voltage Power supply Magic Eye CLOCK 6E1 6E2 IN12 IN14

1. Product Overview

This high-voltage boost converter module is specifically designed to drive Nixie tubes, converting low-voltage DC input (3.3-20V) into adjustable 150-300V high-voltage output. With compact dimensions (23×14mm) and breadboard compatibility, it is ideal for electronic projects like retro clocks.

2. Key Specifications

3. Pin Definitions

(Refer to actual pin diagram on PCB)

• VIN: DC Input Positive (3.3-20V)

• GND: Common Ground (Input/Output)

• EN: Enable Pin (Active HIGH, pulled LOW by default. Must connect to HIGH to activate.)

• VOUT: High-Voltage Output Positive (150-300V)

4. Operating Instructions

4.1 Wiring Guide

1. Power Input:

   • Connect DC power source: VIN(+) to power supply, GND(-) to ground.

2. Output Load:

   • Connect Nixie tube anode to VOUT, cathode to GND via current-limiting resistor (10kΩ-100kΩ recommended).

3. Enable Control:

   • Drive EN pin to HIGH (3.3V/5V logic compatible) to enable output.

   • Leave floating or connect to LOW to disable.

4.2 Output Voltage Adjustment

• If equipped with voltage adjustment (verify module version), calibrate output by:
  a) Using an external potentiometer between designated pins, OR
  b) Modifying feedback resistor values (consult technical support for ratios).

5. Critical Safety Notices

⚠️ LETHAL HIGH VOLTAGE WARNING

• Output exceeds 150V DC! Always power off before wiring.

• Never touch exposed contacts during operation.

⚡ Electrical Safety

• DO NOT reverse input polarity or exceed 20V input.

• Ensure total power <2W (e.g., Max 160mA @12V input).

🌡️ Thermal Management

• Continuous full-load operation may cause overheating.

• Maintain ambient temperature <40°C with adequate ventilation.
