The TEC Controller TEC xx-yy is a controller and driver for Peltier elements. It is a temperature control system with extreme accuracy. The output ripple is very low due to extensive multistage filters. The output is short-circuit-proof. The supply voltage can be a standard industrial voltage of 24 V or 48 V or any other input voltage. The configuration for standard temperature sensors such as Pt100, Pt1000, Ni1000 or KTY 11-5 is already integrated. Other temperature sensors can be defined by the customer. The coefficients of the PID controller can be adjusted by the customer. The user can enter a temperature set-point as well as limits for the temperature and for the Peltier voltage and current. It can be operated via hardware inputs/outputs and/or via software control. It has serial interfaces such as USB or RS232.

The standard temperature range is from 0 °C to +50 °C. In addition, a wide-range version from -100 °C to +200 °C is available.
