The PTC-10 and PTC-20 temperature control systems are designed for heating and cooling purposes in electrophysiological experiments. The PTC-10 system provides one temperature controller channel plus one thermometer channel, whereas the PTC-20 has two fully independent temperature control channels. Both systems are housed in a 19 inch standard rackmount cabinet with built-in power supply and cooling elements for the power devices. The PTC-10/20 system guarantees low noise operation and has special protection features to prevent the preparation from damage.
The PTC-10/20 systems incorporate two electronic thermometers for small semiconductor sensor (standard is R2252, i.e. the sensor has a resistance of 2252 Ω at 25 °C or optionally PT 100, i.e. 100 Ω at 0 °C), two digital temperature displays (XX.X °C), a set value control with direct readout (XX.X °C), a PI (proportional-integral) controller with adjustable parameters, an output power control unit and a high-power bipolar output stage (± 15 V DC, continuous operation) for Peltier elements (i.e. heat / cool operation) or resistive (i.e. heat only) loads with electronic protection circuits. For heat-only applications the bipolar output can be switched to unipolar operation (+15 V). The power output is short circuit protected, the output power is limited electronically. Maximum output voltage is approximately 15 V, the current is limited to 5 A.
The PTC-10 controller is delivered with a power cord and a user manual.
