CL-200

Dual Channel Bipolar Temperature Controller (Warner)
Beschreibung

 

  • Single control temperature adjustment
  • Built-in protection for Peltier devices
  • Heat loss compensation mode
  • Open thermistor fault protection

The CL-200 Dual Temperature Controller is an automatic two channel controller capable of accurately maintaining two Peltier devices between -6° and 65°C. Power for the instrument is provided by an low noise power supply making it suitable for use in sensitive electrophysiology applications. 
While the instrument has broad compatibility, it is specifically designed to control the SC-20 Dual In-line Solution Heater/Cooler in combination with any of our heated and cooled stage chambers.

The CL-200 is simple to use with a single control for temperature adjustment. While total automatic control is provided in the automatic mode, a manual control mode is also available. A loop-speed selector is available to optimize the feedback response of the system to the intrinsic thermal delay characteristics of the setup. 

In addition, the CL-200 has a new heat-loss compensation control that allows the instrument to control the temperature at a location downstream from the temperature source. 
A feedback thermistor switch allows the user to select which thermistor is used for feedback control. Choosing T1 (control thermistor) uses the built-in thermistor attached to the peripheral device. Selecting T2 (monitor thermsitor) allows control at the user selected location of the monitor thermistor (T2).

Built-in circuitry limits the maximum temperature of the Peltier to prevent thermal damage, and a freeze alert/alarm indicates when the cold side of the Peltier reaches 0 °C.
