These heater controllers have been designed to provide quiet electrical power to a variety of perfusion heating devices including Warner Series 20 heater platforms, solution in-line heaters and the DH-35 Series culture dish heaters.
- Slow ramped DC power for quiet operation
- Temperature set with single control
- Manually controlled DC output option
- Three feedback loop speed options
- Independent bath temperature monitoring
The TC-324B and TC-344B temperature/heater controllers have been designed to provide quiet electrical power to a variety of perfusion heating devices including Warner's Series 20 Heated Platforms, the RC-30HV confocal imaging chamber, solution in-line heaters (e.g. SH-27B, SF-28, etc.) and the DH-35i Series culture dish heaters. They also supply heating power to our SW-61 and SW-10/6 syringe warmers, as well as Warner's new product lines the QE-1 Platform for our Series 40 recording chambers and the DH-35i culture dish incubation system.
Each channel can supply up to 18 watts into a load of 8 ohms. Maintenance of heat setpoint is controlled automatically in Auto mode via thermistor feedback. A loop-speed selector allows for selection of three feedback speeds to optimize stability for thermal response characteristics of the device being heated. Heat setpoint maintenance 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 chamber platform, solution heater or other device is automatically controlled to 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 variable DC output adjustable from zero to +12 volts.
Quiet Operation in Recording Setups
Highly filtered DC supplies and slow-ramped analog switching circuitry deliver power without adding noise to the system.
Thermistor Readouts
Each channel reads two thermistors simultaneously: T1 for the control of the system, and a T2 for any point of interest. These temperatures are read on the meter and also available at front panel outputs for recording devices. Unical thermistors are used and can be replaced without the need for recalibration.
