TE Technology TC-36-25-RS232 Temperature Controller

The TE Technology TC-36-25-RS232 Temperature Controller is a bi-directional PID controller engineered to drive TE Technology’s thermoelectric coolers and heaters, using a solid‑state H‑bridge output with MOSFETs and PWM power delivery to enable heating and cooling without relays. It accepts 12 to 36 VDC for its own power and can supply up to 25 A to the TEC device, with a separate TE device power supply recommended for reliable operation; the controller itself draws a minimum of about 200 mA. For installations using two power supplies, TE device power connects to WP3(+) and WP4(–) while the controller power connects to JP6-2(+) and JP6-3(–) (configured with the jumper as described in the wiring instructions). Communication is via RS232 for programmable control and bidirectional data, allowing stand‑alone operation or PC control with Windows‑based software; the software is described as compatible with Windows 10, 8, 7 and XP, and the command set supports configuring setpoints and monitoring feedback. Temperature feedback is provided by a primary thermistor, with optional support for a second thermistor for differential control or sensing over‑temperature conditions. This controller is designed for thermoelectric modules in lab or light‑industrial environments requiring precise, adjustable heating and cooling performance.
