RHM5K-CH TEC Temperature Controllers
Product number:
SW10834
Product information "RHM5K-CH TEC Temperature Controllers"
Output Current TEC ±5 A; Chassis Mount; Supply Voltage 5-30 VDC; Temperature Stability 0.001°C
Wavelength Electronics’ RHM5K-CH series of module type TEC temperature controllers is a 5 A precision temperature controller in a small, chassis mount package. A linear unipolar output stage can be configured for off-ambient control in heating or cooling applications. It drives both TECs and resistive heaters and is suited for applications where heating or cooling (not both) is required.
Operating from a single DC supply, the RHM5K-CH can be used to achieve control at off-ambient temperatures. It uses a PID control loop to drive resistive heaters or thermoelectric coolers. The RHM5K-CH series offers a high level of stability and can drive up to 5 A with a small footprint.
The RHM5K-CH series interfaces with virtually any type of temperature sensor. An onboard sensor bias current source can drive thermistors, RTDs or the LM335. For sensors like the AD590, simply bias it and drive it into the sensor input.
A trimpot adjusts the proportional gain (P). Fixed integrator time constant (I) and differential term capacitors can be custom fit to your application to optimize temperature overshoot and stability. Another trimpot adjusts the setpoint temperature.
Up to 27 V can be delivered to the load with 30 V input. Heatsinking then becomes critical and a safe operating area tool is available to make sure you don’t exceed the maximum internal power dissipation of the package.
Monitor pins bring out both setpoint and actual temperature signals. Current limit is set via a third potentiometer. A single 10-pin terminal strip provides easy access to the DC supply, sensor, resistive heater and measurement connections.
Free, effective and responsive technical support is available to simplify integration of Wavelength products into your OEM design. Standard products can be easily modified to meet your application requirements. Get in touch with the AMS Technologies laser diode driver experts to discuss your customized solution!
