HIGH VOLTAGE POWER SUPPLY C11784 SERIES

Product catalog summary

Overview: The C11784 series is a compact, lightweight, and reliable high voltage power supply module designed for photomultiplier tubes. It offers high conversion efficiency and the capability to drive multiple tubes.

Specifications: The module operates with an input voltage of +24V ± 1.2V and an input current of 55mA. It provides a variable output voltage range from 0 to ±2000V, with a guaranteed output voltage range of -320 to -2000V for the C11784-12 model and +320 to +2000V for the C11784-52 model. The output current is 5mA, with line and load regulation of ±0.01%. Ripple/noise is specified at 50mV peak-to-peak.

Control and Monitoring: Output voltage is controlled via an external voltage (0V to +5V) or a potentiometer (50 kΩ). The module includes high voltage and current monitor outputs, with a reference voltage output of +5.3V. The output voltage setting is determined by the controlling voltage multiplied by 400.

Environmental Conditions: The operating ambient temperature range is 0 to +50°C, with humidity below 85%. Storage conditions are -20 to +60°C with similar humidity constraints.

Protective Functions: The module is protected against reversed power input, excessive controlling voltage input, and continuous overloading or short circuits in the output.

Connection and Pin Assignment: The module features a pin assignment for easy integration, including Vcc, GND, ON/OFF input, control voltage, reference voltage, and monitor outputs. A connection diagram is provided for setup, including ripple/noise reduction using capacitors.

Figures and Diagrams: The document includes connection diagrams, output voltage controlling characteristics, and an example of a ripple/noise reduction circuit. Dimensional outlines are also provided for installation guidance.

Contact Information: Hamamatsu Photonics provides contact details for various global offices, including the USA, Germany, France, the UK, North Europe, Italy, and China.
