Section 1
General Information
1.1 Introduction
Two controllers, the Model 325 and 350, provide superior temperature
stability and a wide range of power outputs. Each has a fast settling,
hybrid P-I control loop that delivers a low noise, bipolar current output in
three operating modes: 1) constant R (thermistor), 2) constant T (IC
sensors), or 3) constant ITE . A user adjustable ITE current limit setting
unconditionally protects the TE modules from damage by excessive drive
current independent of the operating mode. The Model 300 Series is
compatible with thermistors, and AD590 and LM335 Series IC temperature
sensors. Temperature readings (°C) are displayed when using one of these
IC sensors. Model 325 AN and 350 AN include an Analog Interface allowing
remote instrument control and monitoring of display levels.
