The stand-alone precision high voltage power supply is the smallest benchtop power supply that can produce 30 kV.
The benchtop precision high voltage power supply is adjustable up to 30 kV at 1 mA. It is a switching power supply that converts low voltage DC (Direct Current) into regulated high voltage DC. It is incredibly simple to use with intuitive design features meant to get you started quickly. All that is required to get started is for you to plug-in and intuitively control everything from the front panel. The dual adjustment dials and 5-digits displays located on the front panel will give you precise control of the output voltage level. The feedback loop is fine-tuned to give you regulated high voltage output with 0.1% accuracy, ultra-low ripple, and high stability.
The benchtop high voltage power supply can be operated in either constant voltage mode or constant current mode. The maximum voltage output produced by the high voltage DC power supply is 30 kV and the output can be adjusted from 0 to 30 kV. The current output can be varied from 0 to the full rated current of 1 mA.
Remote control operation of the precision high voltage power supply is possible and you can access the remote features through the remote connector located on the front panel. The connection is accessed through the micro HDMI Type-D receptacle and the remote enable pin will give you full remote control of the power supply.
We understand that space is always limited because even the simplest of experiments require many other devices and instruments so, with that in mind, we developed this HV power supply in the smallest size possible. This benchtop equipment is the most compact footprint on the market, leaving you plenty of room to conduct your experiments. Above all, the compact form factor will reduce clutter and integrate easily into your space-constrained systems.
We aim to provide a wholesome product by incorporating a high voltage cable with the connector assembly included as standard. The high voltage cable and connector assembly is rated up to the maximum rated voltage of 30 kV. The whole cable assembly is shielded with a robust stainless steel shell to provide you an additional safety layer and to help prevent physical damage to the high voltage wire insulation. Another benefit of the ground shield is that it helps to prevent capacitive charging and coupling that becomes problematic when operating above 20 kV.
It is essential to have the capability to generate high voltages and electrical field strengths in your lab for scientific development since high gradient electric fields can be used to develop new technology and discover more about the nature of the universe. What Spruce Science offers is a great quality benchtop high voltage switching power supply that is safe and reliable.

Constant voltage mode / Constant current mode
The benchtop high voltage power supply can be operated in either constant voltage mode or constant current mode. These two modes are the two regulating conditions that control the output of the power supply. When it is operating in the constant voltage mode, the HV power supply maintains a constant output voltage that is defined by the operator while the current drawn is varied as required from 0 to the full rated current, which in this case is 1 mA. For this type of high voltage power supply, constant voltage mode is the most common mode of operation.
However, the high voltage power supply can also operate in the constant current mode where the output current is regulated as defined by the operator. When it runs in the constant current mode, the power supply maintain a constant current output into a load while the voltage output is varied as required by the connected load.
The feedback circuit for constant voltage mode and current mode are always active and constantly working together to provide continuous output that is always regulated to user’s input levels. However, it is important to note that although both circuits are always active, only one mode is in control at a time to regulate the output. The response time of these circuits are very fast and crossover automatically as needed between the two modes. Also, the HVPS will enter the constant current mode when faults such as overload, arcing and short circuit occur, thus providing protection.
Remote control of the precision high voltage power supply.

Safety
Your safety is paramount and rigorous safety practices must be enforced to ensure your safety when working with high voltage.
This power supply produces high voltages and store energy that is hazardous. Physical contact with the high voltage output may result in life-threatening or fatal injury.
Before you turn on the high voltage power supply, always confirm first that the dial indicators are turned fully in the counter-clockwise direction and confirm the turn counting indicator reads 0.
Visually inspect the high voltage output connector and any high voltage connections for unintended touching or electrical shorts.
Always keep a safe distance from the test equipment and apparatus or system under test.
Be extra cautious of any high voltage connections that are exposed. Such live terminals should be shielded and barriers must be provided to prevent accidental contact.
Proper grounding is very important. Ensure that a secure ground connection is made between the high voltage power supply and earth ground.
All ungrounded terminals of the test equipment or apparatus under test should be considered as energized.
The work area for the HV power supply should be kept clean. It is important to put away unnecessary parts and components and to keep them far away from the test area.
The general work area around the HV power supply and high voltage connections must be kept dry.
Always consult with your organization’s health and safety expert.
