Q Series, TC-18-QC-50 Temperature Controller The Q Series thermostatic controller is a microcontroller-based device that can be incorporated into a thermoelectric assembly (TEA) to add integrated temperature control. This controller functions as a cooling control device and features an adjustable temperature set point range from 0°C to 10°C. The Q Series controller provides a single directional temperature control for standard or custom thermostatic control with several input and output options. Custom configurations are available, however MOQ applies. FEATURES • Operation in cooling mode • Regulation mode is ON/OFF at the programmed set point and hysteresis Input power range can accommodate 11 to 58 VDC, nominally 12 to • Americas: +1.919.597.7300 48 VDC Europe: +46.31.420530 • Outputs are available for fan, thermoelectric module, NTC Asia: +86.755.2714.1166 thermistor, tachometer sensor, overheating thermostat switch, ets.sales@lairdtech.com alarm, and LED. Some features sold on custom configurations only www.lairdtech.com BENEFITS • The controller’s temperature set point can be adjusted with an internal potentiometer in the internal range of 0°C to 10°C • Tachometer sensor inputs provided to measure the speed of two fans. Sold on custom configurations only • Overheating thermostat switch input available to sense an over temperature condition and will turn off power to TEA. A thermostat is required for operation • Alarm and LED outputs available to indicate functional status of controller MARKETS • Medical diagnostics • Analytical instrumentation • Photonics laser systems Electronic enclosure cooling • • Chillers (liquid cooling) ISOMETRIC DRAWINGS Page 1 of 2 TC-18-QC-50 SPECIFICATIONS Power Voltage 11 to 58 VDC Current 8 A without added cooling / 16 A with added cooling Power 786 W @ 48 VDC Max, 384 W @ 24 VDC Max, 192 W @ 12 VDC Max User Interface Onboard Potentiometer Sensors Temp Sensor NTC Thermistor Fan Tachometer 1 Use with fans w/ an open collector tachometer Fan Tachometer 2 Use with fans w/ an open collector tachometer Outputs Thermoelectric Module Supply voltage @ ≤16 A Fan 1 Supply voltage @ 2 A Fan 2 Supply voltage @ 2 A Alarm Relay Open collector, Opto-isolated Overheating Thermostat Overheating protection LED Status/Errors Alarms Low Voltage If voltage is lower than programmed minimum level the outputs are shut down after a programmed time High Voltage Outputs are shut down instantly Tachometer 1 & 2* If the RPM signal is lover than the programmed minimum level, error is indicated.
