Temperature Controllers

WavelengthElectronics.jpgWavelength Electronics has upgraded its HTC series precision temperature controllers to offer better temperature stability and reduced internal voltage drop. Immune to ambient crossover, the devices provide short-term off-ambient stability of 0.0009 °C and long term of 0.0015 °C. On-ambient stability of 0.002 °C can be achieved with thermistors. The controllers provide up to 3 A of heating or cooling current for medical, defense, communications and manufacturing applications. The linear proportional integral control loop offers maximum stability, while the bipolar current source provides higher efficiency. They maintain precision temperature regulation via an adjustable sensor bias current and error amplifier circuit. External components configure limit current, temperature set point, proportional gain, integrator time constant and sensor bias current.
