The 4479-110 is a 2W miniature high-voltage module designed for photomultiplier tubes and avalanche photodiodes, providing a positive 1kV output at up to 2mA. It accepts a 12Vdc input, operates within a -10°C to +50°C temperature range, and features remote voltage programming via a 0 to +5V control signal with 1MΩ impedance, along with a multi-turn potentiometer for local adjustment. Integrated voltage and current monitors output 0 to +5V proportional to output level, each with ±1% ±50mV and ±1.5% ±50mV accuracy, respectively. The unit includes short-circuit and polarity reversal protection, UL1950 safety certification, and measures 95.2 × 49.0 × 15.0 mm with two 0.1" pitch Molex connectors for input and control and a 0.5m RG178B/U fly lead for output. Fixed +5V and variable 0 to +5V references are provided. All variants share a 50ppm/°C temperature coefficient, <6mVp-p high-frequency ripple, and <20ppm line and load regulation.
A product line known for its robust construction and precision, suitable for applications requiring high-performance standards.
