Request InfoWavelength Electronics Inc.The WTCP5V5A thermoelectric temperature controller from Wavelength Electronics combines pulse-width-modulated control with improved temperature stability for portable, airborne and other space-constrained temperature-control applications. It can operate from a single 5-V power supply, or together with the load can be driven from separate power supplies when lower-output current noise is required. The available WTCPEVAL circuit board can configure the device for a range of applications and load conditions. The 5-A device features separate heating and cooling current limits to...See full productRelated content from Photonics MediaPRODUCTSPhotonics Spectra May 2024 IssueLaser SpectrometerThe TDLS8220 from Yokogawa Corporation of America is an extractive tunable diode laser spectrometer for extractive oxygen measurements where in-situ or probe-type installations are not applicable....Photonics.com 7/27/2023Miniature Linear Voice Coil Servo MotorsThe LVCM-025-029-02 and LVCM-025-029-02M miniature linear voice coil servo motors from Moticont are 1-in. diameter brushless devices.
