Mar 20, 2009
The Optotherm HP20 provides precise temperature control (+/-0.01C) of thermoelectric modules and heating/cooling stages within a temperature range of -40C to +250C.
The HP20 operates in a bi-directional, H-bridge configuration for smooth transitions between heating and cooling cycles and provides output current of up to 20A at 12VDC.
The HP20's PID capabilities are claimed to 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 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 set-point 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.
It features plotted temperature data and step-by-step instructions, facilitating the process of setting correct PID control parameters.
