Thermal imaging specialist OptoTherm introduces high-power thermoelectric controller
March 19, 2009
SEWICKLEY, Pa., 19 March 2009.paste link here specialist OptoTherm Inc. in Sewickley, Pa., is introducing the HP20 high-power thermoelectric controller for applications in military thermal imaging such as a thermal sight, electronics, security, and medical.
The OptoTherm HP20 provides precise temperature control to within 0.01 degrees Celsius of thermoelectric modules and heating/cooling stages within a temperature range of -40 to 250 C.
The HP20 operates in a bi-directional, H-bridge configuration for smooth transitions between heating and cooling cycles and provides output current as strong as 20 amps at 12 volts DC.
The HP20's PID capabilities enable rapid response to changes in operating conditions and provide tight control over a broad temperature range. TE View, the included PC-based software, provides an intuitive interface for configuring and operating the controller via the controller's serial (RS-232) interface.
Once the controller is configured, the computer can be disconnected and the controller can be operated manually using the front panel push-button interface.
When the controller is connected to a PC, the setpoint and actual temperatures can be plotted in real time, providing a temperature history that can be saved in ASCII text format and imported into data analysis programs. Using plotted temperature data and the included step-by-step instructions, setting correct PID control parameters has never been easier.
