Request InfoWavelength Electronics Inc.BOZEMAN, Mont., Feb. 1, 2011 — The RHM5K-CH from Wavelength Electronics is a unipolar device that achieves precision control at off-ambient temperatures. The proportional-integral-derivative control loop drives resistive heaters or thermoelectric coolers. Offering high stability of < 0.003 ºC, it can supply a drive current of up to 5 A and has a small footprint. Onboard 12-turn trimpots control temperature set point, proportional gain and output voltage limit, all of which are user-adjustable. A single 10-pin terminal strip provides easy access to the DC supply, sensor, resistive heater and measurement...See full productRelated content from Photonics MediaPRODUCTSPhotonics Spectra November 2022 IssueBroadband Antireflective WindowsTextured Broadband Antireflective Windows from Thorlabs Inc. feature textured surface technology for next-generation laser and sensing applications.
