The Model PS/TC-1 integrated low noise power supply and thermoelectric cooler controller is designed to oper-ate photodetector preamplifiers and single and multi-stage thermoelectric coolers. The detector preamplifier usu-ally requires a + - 15V input and ground for optimum gain, bandwidth, and noise performance. Pin 6 (+Vin), Pin 7 (-Vin), and ground are dedicated to the photodetector preamplifier. Verify wiring before activating the amplifier to avoid potential failure. The detector amplifier activates immediately when power is applied. The PS/TC-1 controller is designed to work with a thermistor mounted to the cooler’s cold plate, and provides a stability of + - 0.003 oC . The set point of the controller is continuously variable using the front panel potentiome-ter. The control unit range is between room temperature and –60 C, dependent on the cooler and heat sinking utilized. A DC ammeter is provided for monitoring current, as well as a green LED status indicator which, when lit, indicates the cooler is controlled as set. The controller is connected to the cooler assembly through four shielded leads. Before connecting to the cooler, verify wiring. Pin 1 is the cooler positive lead, Pin 2 is the cooler negative lead and Pins 3 & 4 are the thermistor leads. Thermistor leads should not be grounded. After making connections to the cooler, check to insure that no shorts occur between any leads.
