Key specifications

Voltage	0 to -30 kV
Current	0.4 mA
Accuracy	±1%
Control	Local Control

LabMate 30 delivers adjustable 0 to -30 kV DC output at up to 0.4 mA in a compact benchtop instrument. Turns-counting controls, separate five-digit voltage and current displays, and automatic constant-voltage/constant-current crossover provide practical control for research, development, testing, and integration requiring a wider voltage range.

Why choose LabMate 30 - Negative, Local Control

Keep operation direct. Adjust voltage and current from the front panel without adding an external control interface.
Set voltage and current with confidence. Turns-counting dials provide fine adjustment, while separate five-digit displays keep both output values visible.
Extend your voltage range. Reach 30 kV in a compact benchtop instrument designed for higher-voltage laboratory work.
Connect with the included high-voltage cable. The shielded, quick-disconnect assembly is supplied with the instrument.
Operate across changing loads. Constant-voltage and constant-current regulation cross over automatically as load conditions change.

Control

LabMate operates as a self-contained benchtop instrument. Two turns-counting dials independently set the voltage and current limits, and separate five-digit displays show the live output voltage and current. A front-panel indicator identifies constant-current operation. This Local Control configuration is intended for setups where the operator will adjust and monitor the supply at the instrument. If your system requires external programming, monitoring, or high-voltage enable control, choose the Analog Remote configuration instead.

Automatic constant-voltage and constant-current regulation

LabMate 30 continuously monitors voltage and current and regulates whichever limit the load reaches first. In constant-voltage (CV) mode, the supply maintains the selected output voltage while the load draws current up to the set current limit. In constant-current (CC) mode, the supply maintains current at the selected limit while allowing voltage to adjust to the load. The supply crosses between CV and CC operation automatically. During an overload, arc, or short-circuit event, the current limit takes control. Current limiting is an operating function; it does not eliminate the need for appropriate high-voltage safeguards.

Connector assembly

Every LabMate 30 includes Spruce Science's coaxial high-voltage connector system. A central high-voltage conductor is surrounded by insulation and a grounded outer shield, which helps reduce capacitive coupling and electrical noise while adding a grounded barrier around the high-voltage path. The supply-side assembly is fixed to the instrument and protected by a robust stainless-steel connector shell. The included two-foot user-side cable connects through a quick-disconnect coupling. A 47 kOhm series resistor in the user-side assembly helps limit surge current during unexpected arcing events. The connector and cable assembly are rated up to 30 kV.

High-voltage safety: LabMate 30 produces hazardous high voltage and can store dangerous energy. Contact with the high-voltage output may cause serious or fatal injury. Use the instrument only by trained, qualified personnel within an appropriately designed, grounded, guarded, and interlocked system. De-energize the supply, verify zero output, and discharge stored energy before making or changing connections. Follow the user manual and your organization's electrical-safety procedures.

Choose the correct configuration: This is a fixed-polarity supply. Positive and negative LabMate supplies are separate products and are not field-switchable — confirm the polarity required by your application before ordering.
