Model PPM1/112N PRECISION PHOTOMULTIPLIER POWER SUPPLY MODULE FEATURES  0.77W output power Օ Negative polarity  Small size, lightweight High performance for precision applications High reliability Short circuit & overload protected CC marked DESCRIPTION The PPM1/112N is a compact, high reliability, photomultiplier power supply module which has considerable advantages in size, weight and specification over other competitive units for photomultiplier applications; and for those applications where 1W output power is sufficient and high performance is essential. These applications include microchannel plates, precision lenses, image intensifiers, and other general precision uses. Line, load and ripple performance, together with many other aspects of the specification, are all you would expect from this professional photomultiplier module and, due to the wide input range of 14V to 23V DC, the unit can be used with various types of DC input supplies. SPECIFICATION Output Power: 0.77W at full rated output voltage and current. Output Voltage: -1.1kV max. Output Current: 0.7mA max. Input Voltage: 14V to 23V DC (pins 1 and 2 joined). Note: If preferred, the voltage on Pin 2 can be lower than the voltage on Pin 1. Input Current: 140mA max (pins 1 and 2 joined), or 130mA max pin 1, 10mA max pin 2. Output Polarity: Negative. Line Regulation: Less than 0.1V (100ppm) output change, for a 14V to 23V input change. Load Regulation: Less than 0.1V (100ppm) output change, for a change from 0 to 0.7mA load current. Ripple: Less than 25mV peak to peak at rated output voltage and current. Voltage Control: 0 to 1.4V input for -1.1kV to -200V output (pin 4). (Vout = Vin x 657 - 1100) tolerance ±40V. Resistance Control: 0 to 10kQ input for -1.1kV to -200V output (pin 3 to pin 4). (Vout = 2300/ (15200/R+1) - 1100) tolerance ±60V). Temperature Coefficient: Better than 50ppm/°C at max output voltage and load current. Operating Temperature: 0°C to 50°C at up to 90% RH non-condensing. Altitude: Sea level to 2000 metres (6500 feet). Stability: Better than 200ppm/hour after warm-up, measured at rated output voltage and current with constant ambient temperature. www.hitekpower.com
