High Voltage Generator (60kV DC)

Embark on a journey into advanced electrical experimentation with the HVGD-60 high voltage generator. An upgrade from our 30kV model, this generator offers an exceptional 60kV DC output, adjustable to cater to a variety of high-intensity experimental requirements. With a solid 400W power output and a current capacity of up to 10mA, it is well-equipped for demanding high-voltage applications.

Prioritizing both performance and safety, the HVGD-60 includes a built-in fan for efficient thermal management, ensuring it stays cool during extended usage. It can generate both positive and negative voltages, providing greater flexibility in experimental setups. Notably, this model features an adjustable spark-over protection function that monitors the current flowing through the system. When a spark or plasma channel is established, the current will usually increase significantly. The protection adjustment knob is therefore used to set the expected steady-state operating current threshold. If the current rises above the preset threshold, the unit automatically cycles the output power with an interval of approximately half a second, giving the spark enough time to extinguish before normal operation resumes. The protection function can also be disabled for experiments where spark generation is key.

Designed for ease of use, the generator has a front-facing on/off switch, simplifying operation for a variety of high-voltage tasks. It is particularly effective at charging high-voltage capacitors and producing intense sparks, making it ideal for electrostatic experiments. Its dependable performance also makes it suitable for research involving static electricity, offering adaptability for numerous scientific investigations and high-voltage procedures.

We also offer an optional version with TTL signal input through a BNC connector, allowing the high-voltage output to be switched on and off using a 3.3V or 5V logic signal. This enables significantly faster output switching compared with using the front panel power switch and allows programmatic control from an MCU, PLC, signal generator, or similar control system. The TTL-enabled version can generate high-voltage pulses as short as approximately 300 µs, with repetition frequencies up to 1 kHz.

Both the standard version and the TTL input version can also be easily modified so that the output voltage and protection threshold can be adjusted using a 0-5V control signal. This makes the unit suitable for integration into automated test systems, MCU-controlled setups, PLC-controlled systems, and other externally controlled high-voltage applications. Please contact us for details on how to implement this modification.

Like our previous 30kV model, the HVGD-60 is provided without a wall socket plug, giving you the flexibility to select an appropriate adapter for your local standards or integrate it seamlessly into your existing laboratory power setup.

Important operating notes: This is an unregulated DC high-voltage power supply. Maximum output voltage is measured under no-load / very light-load conditions using a 1000 MΩ high-voltage probe. Output voltage decreases as load current increases, and the actual operating point depends on the connected load, input voltage, and internal conversion characteristics.

Maximum voltage, maximum current, and maximum power are separate ratings and should not be expected at the same time. Maximum output power is typically achieved when the load impedance is reasonably matched to the supply output characteristics, which is commonly in the range of approximately 1 MΩ to 10 MΩ depending on the specific unit and operating conditions. For the TTL input version, the TTL input is pulled low by default, meaning the high-voltage output remains off when the TTL input is left unconnected. For normal continuous-output operation on the TTL-enabled version, the TTL input must therefore be driven high using a 3.3V or 5V logic signal.
