Controller C16137 series

The C16137 series is a bench-top power supply unit with a temperature control function. Just connecting to an AC source of 100 V to 240 V generates the output voltages for the thermoelectric cooler and the fan, which are needed for the H15620 series operation. The photomultiplier tube temperature can be maintained to -30 °C by monitoring the thermistor and regulating the output current for the thermoelectric cooler. Control voltage can be varied by a dial on the front panel.
