These modular TEC temperature controller cards are intended to be used within a host mainframe. They contain either one or two independent temperature controllers that each drive a thermoelectric cooler (TEC) and feature a bi-polar current driver that works with most TEC modules to deliver precise temperature control over a wide range of temperatures. The temperature controllers operate using thermistor type temperature sensors only. They feature TEC module voltage measurement, selection of thermistor current range, and control loop gain adjustment from 1 to 127.
- Temperature controllers with up to 3A TEC current
- Bi-polar current driver for precise temperature control

Features
TEC Module and Connections
The 15-pin connectors on the rear panel of these controller cards are used to make connections to thermoelectric cooler (TEC) modules and their associated thermistors. There are connections provided for current drive and temperature sensor. Also provided are connections to earth ground (chassis), and to the modules analog ground. The TEC Module pins are isolated from chassis ground, allowing either output terminal to be connected to earth ground at the user's option.
Safety Limits
The 3916550 series controller cards provide a current limit feature that allows you to set the maximum current that the controller will supply. Also, to help avoid thermal runaway damage, these controller cards provide a high temperature limit setting. When the load temperature exceeds this setting, they will turn off the TEC current and generate an error.
Powerful GPIB Interface
Newport's Modular Laser Diode Cards' response to sensing the various limits can be controlled via the GPIB interface. Most high limit responses can be set to either turn off the source or just give a limit warning through the GPIB interface.
