Flexible Heaters

Output Current TEC ±5, ±5, ±15 A; Benchtop or Rack Mount; Supply Voltage 100-240 VAC; USB, Ethernet Communication Interface; Temperature Stability 0.0009°CWavelength Electronics’ TC LAB series of instrument type temperature controllers integrates high-end digital control with a precision output current drive stage to offer the best stability temperature control instrument commercially available today. Many different sensors can be used in the feedback loop including thermistors, RTDs, linear current and voltage sensors. Within the TC LAB series, three models are available driving a thermoelectric or resistive heater with maximum currents of 5 A (TC5 LAB) and 10 A (TC10 LAB) with 15 V compliance, or even 15 A maximum (TC5 LAB) with 20 V compliance. The advanced and reliable circuitry of the TC LAB series instruments achieves better than 0.0009 °C temperature stability with thermistors. Safety features protect the thermoelectric cooler [TEC] and its load. Over and under temperature limits as well as positive and negative current limits can be set. If the sensor signal is lost or a short is detected at the TEC, output current is disabled. If temperature limits are exceeded, a signal to the active load can be sent to disable its current. For example, connect the LD Shutdown BNC output to the Active Lock input on Wavelength Electronics’ QCL LAB driver, and the QCL current will shut down if temperature limits are exceeded. An auxiliary sensor can be used to monitor the temperature of the system heatsink. With Wavelength’s plug and play instrument, you have the ability to quickly set the controls using either the instrument touch screen or a remote computer, and results are easy to monitor. This allows taking your temperature-controlled application from the test bench to market quickly and efficiently. Wavelength Electronics’ proprietary IntelliTune® algorithm characterizes the TEC/sensor system’s response to the controller and determines the optimal PID control coefficients. It then automatically adjusts the PID control values as setpoint, tuning mode, or bias current change. Run IntelliTune® easily just off ambient and watch it change PID settings for a much higher or lower setpoint. After a single scan, explore either optimized setpoint response or disturbance rejection performance with your load to see which works best. Add or remove the D term to see if noise is an issue. IntelliTune® lets you skip the manual characterization and it’s smart enough to really work—very little adjustment is needed after you have stored a successful characterization scan. See Application Note IntelliTune® vs. Conventional Autotune for an in-depth exploration. One mating DB 15+2 thermoelectric and sensor plug is included with the instrument. As accessories, various further devices are available, like a DB9 mating connector for status/enable signals, a DB15+2 male connector with hood and high current pin inserts, full cables for the DB9 and DB15+2 or single and dual rack mount kits. When controlling laser diode temperature, the LDMOUNT-5A, a 14-pin butterfly laser diode mount with integrated heat sinking, is available for simple connections between the instrument and the laser. If you need a lower power temperature control instrument, consider the LFI3751 series. 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!

Max. Temperature +1,600 °C; Voltage 15 to 19 VAC; Current 5,8 to 7 A; Length 19, 22 mm; Width x Height 20 x 25 mm; Internal Diameter of Heat Core 2 mm NTT-AT’s CMH series of ceramic micro heaters provides temperatures of up to +1,600 °C in a very small, cylindrical volume. Powered by AC current with a power of approximately 100 W, a tubular ceramic micro-heating element with an internal diameter of 2 mm generates these high temperatures over a length of 19 (CMH-7019) or 22 mm (CMH-7022). In order to focus the heating energy in this small volume and to minimize the losses to the environment, the actual heating element is enclosed in a very high heat resistant ceramic material. An approx. 1 mm wide gap in this material on one side makes the laterally open, tubular heating element accessible from the outside. The main application of ceramic micro heaters is the processing of optical fibers, which can be inserted into the ceramic micro heater through the lateral gap. Tapering of optical fibers, for example, involves heating a small area of the fiber to a high temperature while the fiber is gently stretched as evenly as possible. This procedure reduces the diameter of fiber and core in the heated area, resulting in a tapered fiber. Another application of ceramic micro heaters is the production of fiber couplers. Key Features: Ideal for Heating-up Optical Fibers Ideal for Manufacturing of Tapered Optical Fibers or Optical Fiber Couplers Operated by Electric Current Temperatures of up to +1,600 °C Can Be Generated Precise Temperature Control Heating Element Inner Diameter: 2 mm Two Lengths Available: 19 mm (CMH-7019) and 22 mm (CMH-7022) Width: 25 mm, Height: 20 mm Applications: Heating-up Optical Fibers; Manufacturing of Tapered Optical Fibers; Manufacturing of Optical Fiber Couplers

35 to 450 A RMS; Single Terminal; 28 to 45 kV; Mechanical Life 0.5 to 2 Mio. OperationsJennings Technology’s series of vacuum interrupters handle a wide range of voltage and current interrupt levels, and high-quality and highly reliable interrupters are available for the utility and industrial markets.Current interruption in a vacuum is recognized as the ideal switching technology in the medium voltage range, and it is also applied in high-voltage and low-voltage applications. Excellent switching capabilities and compact design make vacuum interrupters the most economical switching device solutions possible.Jennings vacuum interrupters feature an evacuated ceramic insulating envelope surrounding two contacts, one fixed and one movable. The movable contact is operated from the outside through a metallic bellows. Contacts are typically a copper alloy that is developed for use in AC voltage applications. The end plates are made of stainless steel or copper.With these features, vacuum interrupters can be expected to last the life of the equipment in which they are installed. Their interruption mechanism is independent of the current magnitude, so interruption can normally be anticipated at the first current zero with no restriking, as the dielectric strength of the contact gap recovers more rapidly than the recovery voltage can rise.Vacuum dielectric enables the interrupters’ contacts to be arranged close together, so circuit interruptions can be designed in a smaller envelope. With current interruption occurring in a vacuum, all arcing is confined within the vacuum interrupter body, so Jennings interrupters are noise-free and flash-free, avoid contact contamination as oxides and corrosion layers cannot form in vacuum, and they do not emit any greenhouse or toxic gases.Key Features: Long Life, High Reliability Controlled Contact Erosion Results in Virtually Maintenance-free Operation Fast Interrupting Speed Rapid Dielectric Recovery High Cycle Withstand Voltages Robust, Compact Design Environmentally Friendly Atmospheric Contact Contamination is Eliminated Noise-free and Flash-free Applications: Load Break Switches; Contactors for Industrial and Motor Control; Capacitor Bank Switching; Circuit Breakers; Specialty RF and DC Applications

Small Multi Stage Peltier Modules; 3 x 3 to 21 x 21 mm; Height 2.7 to 10.2 mm; Max. Cooling Capacity 0.12 to 14 W; Max. TEC Current 0.32 to 7.8 A With SmarTThermoelectrics’ M-Series, AMS Technologies offers multi stage small thermoelectric coolers (TECs, Peltier Modules) from two to five cascades with maximum temperature differences between its cold and hot side of up to 130 K. Here you can find cascade TECs with standard pyramidal design, TECs with enlarged surface of the top cascade (cold side) to work with relatively big cooled objects as well as linear cascade TECs, especially designed for deep cooling of long objects like CCDs or detector arrays. The M-Series’ bottom dimensions range from 3 × 3 to 21 × 21 mm and heights from 2.7 to 10.2 mm, with maximum cooling capacities from 0.12 to 14 W. The MS subseries of multi stage small thermoelectric coolers provides TECs with standard pyramidal design from 2 to 5 stage cascade, while the ME subseries features an enlarged surface of the top cascade (TEC cold side = TEC hot side). This technology enables the ME subseries to provide the same cooling capacities and temperature differences as traditional pyramidal TECs but at bigger surface area of the cold side. Increased area and mechanical strength of the top cascades gives a possibility to work with relatively big cooled objects. Linear cascade multi stage small thermoelectric coolers are the domain of SmarTThermoelectrics’ ML subseries. This variation of the ME-subseries TECs is especially designed for deep cooling of oblong objects like CCDs, detector arrays etc. And last but not least, the MI series of multi stage small thermoelectric coolers provides cascade TECs implemented with increased TE pellet density technology and thus with increased cooling density for demanding applications.
