Details

The TC-10 and TC-20 temperature control systems are designed for heating purposes in electrophysiological experiments. The TC-10 has one temperature control channel and one additional thermometer, whereas the TC-20 provides two independent temperature controller channels. Both systems are housed in 19″ standard cabinets, with built-in power supply and cooling elements for the power devices. The TC-10/20 system guarantee low noise operation and have special protection features to prevent the preparation from damage.

Each system incorporates two electronic thermometers for small temperature sensors (standard is R2252, i.e. the sensor has a resistance of 2252 Ω at 25 °C or optional PT100, i.e. the sensor has a resistance of 100 Ω at 0 °C), two digital temperature displays (XX.X °C), a set-point control with direct readout (XX.X °C), a PI (proportional-integral) controller with adjustable parameters, an output power control unit and a high-power output stage (DC, continuous operation) for resistive (i.e. heat only) loads with electronic protection circuits. The power outputs are short circuit protected, the output power is limited electronically. The maximum output voltage is approximately 12 V, the current is limited to 2 A.

The system can be connected to the thermistors / heating elements in two ways:

– Using separate cables for the sensors and the heating element or

– Using the ALA DIN cable assembly that connects both, sensors and heating elements, e.g. ALA HPT-2A

The TC-20 controller is delivered with a power cord and a user manual. Sensors must be purchased separately.
