HVPS-300 High-Voltage Power Supplies (MHz-Class Pockels Cell Drivers) HVPS-BT-300-4kV
HVPS-300 is a dedicated high-precision DC high-voltage power supply with bipolar output. Its output connector has three pins: ground, positive high voltage and negative high voltage. The HV positive and HV negative potentials are always equally spaced from ground; 4kV output is produced by +2kV at the HV positive pin and -2 kV at the HV negative pin. Its highly stable bipolar HV output makes HVPS-300 suitable mainly for driving high-voltage, high-repetition-rate Pockels cells commonly used in the laser industry. The module provides DC high voltage, adjustable up to 4kV by default, with higher voltages negotiable. Maximum output power exceeds 300W. A fan provides active cooling. All interfaces are analog by default, with digital interfaces available on request. Versions: a plug-in benchtop version for laboratories (100-240V AC), and an embedded version for integration powered by 24V DC. Input voltage: HVPS-300: 24VDC; HVPS-BT-300: 100-240VAC. Original technical-table output capacitance: depends on change. Common models (original table): HVPS-300-2kV | maximum output voltage 2kV, maximum output power exceeds 300W@2kV and decreases steadily with output voltage, output capacitance 13.5uF; HVPS-BT-300-2kV | benchtop version of HVPS-300-2kV; HVPS-300-4kV | maximum output voltage 4kV, maximum output power exceeds 300W@4kV and decreases steadily with output voltage, output capacitance 3.3uF; HVPS-BT-300-4kV | benchtop version of HVPS-300-4kV.
