Newport 350AN

The Newport 350AN is a precision temperature controller designed for stable thermal management in sensitive experimental setups. It delivers low-noise, bipolar current output and supports three independent control modes—Constant R for thermistors, Constant T for IC sensors, and Constant ITE for thermoelectric modules. The hybrid P-I control loop enables fast settling while a user-adjustable current limit unconditionally protects TE modules from overcurrent across all operating modes.
