(TC-344C) Dual Channel Temperature Controller
Product Summary
- Slow ramped DC power for quiet operation
- Temperature control from ambient to +65C
- Manually controlled DC output choices
- Three feedback loop speeds
- Independent bath temperature monitoring
- External input for computer control
- Open thermistor fault protection
- Low noise toroidal transformer power supply
Each channel supplies up to 22 watts into a load of 10 ohms. Heat set-point is controlled automatically in Auto mode via thermistor feedback. A loop-speed selector provides three feedback response times to optimize tp the thermal stability of the device being heated. Heat set-point may also be manually controlled in Manual mode.
Ease of Use
In Auto mode, the desired temperature is set with a single set temperature control. The connected platform, solution heater, or other device is automatically maintained at the set temperature. Accuracy is typically better than ± 1°C, and under ideal conditions will approach ± 0.1°C. In Manual mode, the controller provides a continuous DC output adjustable from 0 to +15 volts.
Quiet Operation in Recording Setups<
Highly filtered DC power supplies employing toroidal transformers are used to eliminate AC noise and deliver the high-level of isolation required for sensitive electrophysiology applications. Slow-ramped analog switching circuitry delivers power without adding noise to the system.
Unique Features
An open-thermistor fault protection circuit prevents overheating of the sample in the event of a thermistor failure. Remote control of the set temperature allows a computer to control the sample temperature.
Thermistor Readouts
Each channel reads two thermistors simultaneously: T1 for feedback control of the system, and T2 for measurement of any point of interest. These temperatures are displayed on the meter and are also available at front and rear panel outputs for recording devices. Unical thermistors are used and can be replaced without the need for recalibration.
