Variable HVDC PSU

About this component

he ZTM-HIVO-6K is a variable high-voltage source for low-power electric-field generation. Output voltage is controlled through the ZapLink TWI interface and can be adjusted from approximately 1,000 V to 6,000 V in fine steps.

The module is intended for applications where high voltage is needed, but only very small currents are required. On-board output limiting further restricts the available current to approximately 25 µA, making it well suited to ion transport, electrostatic field generation, and cloud chamber ion sweeping.

Typical applications include:

• Cloud chamber ion sweeping
• General electrostatic particle and ion experiments
• Ion wind and electrohydrodynamic experiments
• Electrospinning
• Electrostatic flocking for model making and surface finishing
• Other low-current high-voltage laboratory experiments

Why use a commercial HV module?

Producing several thousand volts is not difficult in principle. Producing it cleanly, repeatably, and safely inside a finished product is a different problem.

Rather than using a basic discrete diode ladder as the main high-voltage generator, the ZTM-HIVO-6K uses an XP Power E60 high-voltage module. This gives the design a proven encapsulated HV stage with proper insulation, compact construction, and predictable behaviour under light-load conditions.

For the end user, this means the expensive part of the module is doing important work. It is not just “making high voltage”; it is making high voltage in a controlled, insulated, product-ready way.

Control options

The standard version is controlled digitally through the ZapLink TWI interface, allowing the output voltage to be set by a compatible controller.

For custom applications, the design can also be adapted for fixed-voltage operation or manual adjustment using a variable resistor.

High-voltage safety

Although the ZTM-HIVO-6K is deliberately current-limited, it still generates up to 6,000 V DC and should be treated as high-voltage equipment.

Do not touch the high-voltage output while powered. Allow time for external loads and electrodes to discharge after use, and make sure the module is mounted with appropriate clearance, insulation, and strain relief. Sharp conductors, exposed terminals, contamination, and poor wiring layout can encourage corona discharge or arcing.

Used correctly, the module provides a convenient low-current high-voltage source for controlled electrostatic experiments. Used carelessly, it can still bite.
