High-Voltage Power SupplyIon Pump Controller
2800~5000 V adjustable · sub-nA current measurement · Modbus remote monitoring
A smart high-voltage supply for miniature ion pumps and UHV systems. Its single output adjusts from 2800 to 5000 V in 100 V minimum steps with voltage stability better than 2%, while 0.1 nA-level current measurement converts ion current into a live vacuum readout (10⁻³~10⁻¹¹ Pa, switchable to Torr or mbar) — no separate gauge required. Operate locally on the 3.5-inch color touchscreen (auto brightness and sleep), or connect a host computer over USB Type-B or Ethernet — with modbus-rtu and modbus-tcp support — to read voltage, current and pressure and configure parameters. A front-panel hardware HV enable switch (lit green when output is allowed) cuts high voltage when released and locks out remote turn-on; the unit is powered over USB Type-C (15 V / 12 V) and can run from a vehicle or battery supply. It is the standard companion controller for LinQ's miniature combination ion pump, and is also available separately.
Key Features
A high-voltage supply, a vacuum gauge and a remote-monitoring terminal in one box.
Hardware HV Enable Switch
A metal front-panel enable switch: pressed and lit green, high voltage is allowed; released, HV is cut and locally locked out so it cannot be switched on remotely — one press makes cable work safe.
Wide-Range Adjustable HV
Single 2800~5000 V output in 100 V minimum steps, stability better than 2%; to change the target voltage while running, switch HV off first and set the new value.
Sub-nA Current Measurement
0.1 nA-level current resolution converts ion current directly into vacuum readout across 10⁻³~10⁻¹¹ Pa, switchable to Torr or mbar.
Touchscreen + Remote Control
3.5-inch color touchscreen for local operation (auto brightness and sleep); USB Type-B or Ethernet host link with modbus-rtu / modbus-tcp support to read voltage, current and pressure and set parameters.
Comprehensive Output Protection
Max output current ≥200 µA at 5000 V; over-current, over-voltage and under-voltage protection safeguard both pump and supply.
Works With LinQ Products
The standard companion controller for LinQ's miniature combination ion pump; offered as a benchtop instrument or an embedded module for OEM systems.

Application Fields
Ion Pump Operation
The standard supply for miniature combination ion pumps — high voltage, current measurement and vacuum display in one unit.
Portable & Transport Scenarios
Low-voltage 15 V / 12 V power from a vehicle or battery supply keeps vacuum alive during system transport and outages — suited to portable quantum-sensing instruments.
Remote Monitoring & Automation
Connect to a host over modbus-rtu / modbus-tcp to read voltage, current and pressure and control HV remotely — ideal for long-term unattended vacuum monitoring.
Laboratory UHV Systems
HV supply and vacuum monitoring for cold-atom setups, surface-science and analytical instruments with compact UHV chambers.
OEM Integration
The module variant drops the human interface and runs entirely over its data interface — ready to embed in quantum systems and automated equipment.
