New release of the high voltage module as well as the previous version is a miniature ultra-thin (5 mm) and low-power DCDC_3V3_400V_V1 module with the ability to generate high voltage at low input voltage and consumption. This product is made by IoT-devices with freedom & wisdom in Ukraine.

Application of the DCDC_3V3_400V_V1 module

The module was designed for use as a high voltage source for Geiger-Muller tubes but the technical characteristics of the module make it possible to use in other kinds of projects. Here are just a few recipes:

• Power supply of retro symbol gas-filled indicators;
• Devices for protection against mosquitoes, ozonizers, etc.

What's improved in the new version?

The new version of the DCDC_3V3_400V_V1 module has improved stability of the output high voltage level depending on the input supply voltage level in the range from 2.4 volts to 5.5 volts.

Important instructions

The module is sold with a preset output voltage level 400 volts and is ready for use.

Connect the power supply via the μUSB connector or two VCC & GND inputs. Connect the high voltage load to the High voltage and GND outlets.

In case the user needs to change the output voltage level, it is necessary to:

Step 1. Connect load to the output High voltage port (for example, a resistor of 10 MOhm and in parallel to the resistor a capacitor of 300 nF, 600 V).

Step 2. Use a high impedance multimeter (10 MOhm) to control the high voltage level.

Step 3. Connect Power Supply source to input port (2,5 - 5,5 volts recommended).

Step 4. Use the potentiometer on board and set the output voltage level as you need.

Warning! Keep out other electronic or electrical circuits to the high voltage connectors of the module because this may damage these devices.
