PTCxK-CH Series TEC Temperature Controllers

Output Current LD 2, 5 A; Output Current TEC 5, 10 A; Benchtop or Rack Mount; Compatible with Type A, B & C Lasers  Wavelength Electronics’ LDTC LAB series of instrument type laser diode and TEC temperature controllers combine best-in-class low noise, high-end digital control laser diode driver technology with an IntelliTune® smart TEC temperature controller. If you need stable wavelength, stable temperature (better than 0.0009 °C with thermistors), stable laser diode current or power, or low noise (RMS laser driver noise as low as 7 µA), these offer the best performance and value. Two models are available, the LD2TC5 LAB and the LD5TC10 LAB. The LD2TC5 LAB outputs up to 2 and 5 A for the laser and thermoelectric, respectively. The LD5TC10 LAB outputs up to 5 and 10 A. Both models offer 10 V of laser compliance voltage and 15 V of thermoelectric compliance voltage. The touch-screen interface makes operation intuitive and simple. A LabVIEW® virtual instrument, remote command set, and USB interface allow integration into an instrument library. Operation in Constant Current (CC) or Constant Power (CP) mode changes with the touch of a button. A wide variety of sensors work in the temperature control feedback loop. Safety features protect the thermoelectric cooler (TEC) and the laser. Over- and under-temperature limits on the load, positive and negative (where applicable) current limits, and voltage limits can be set for both TEC and laser. If the sensor signal is lost or a short is detected at the TEC, output current is disabled. Passive and active interlocks are available for safety of equipment and user. Automatic laser shutdown upon TEC error is also available. You can link laser diode current to safe and stable thermoelectric operation. With Wavelength Electronics’ 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. 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. An Interlock Kit containing a BNC terminator for the laser interlock and a pre-soldered DSUB to satisfy the laser interlocks is included with the instrument. Loose connectors for custom cable configuration are shipped with the unit. Full cables for both the laser connection and the thermoelectric connection are available. The LDMOUNT-5A, a 14-pin butterfly laser diode mount with integrated heat sinking, is available for simple connections between the LDTC LAB driver and the laser. 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!

5 A; 1 channel; 30 V; chassis mount Operating from a single DC supply, the RHM5K-CH can be used to achieve control at off-ambient temperatures. It uses a PID control loop to drive resistive heaters or thermoelectric coolers. The RHM offers a high level of stability and can drive up to 5 A with a small footprint. On-board 12-turn trimpots control temperature setpoint, proportional gain, and output voltage easy access to the DC supply, sensor, resistive heater, and measurement connections. The RHM5K-CH is suited for applications where heating or cooling (not both) is required. This product is ideal for applications where temperature stability is critical and space is tight, such as heated optics (non-condensing circumstances), CCDs, preheated liquids and chamber stabilization.

The PTC-CH Series Chassis Mount Temperature Controllers deliver the precision performance and long-term reliability you expect from a Wavelength Electronics temperature controller. PTC-CH Series controllers are found in such diverse applications as particle and droplet measurement, manufacturing machine vision systems, biomolecular interaction analysis, and more.The PTC-CH controllers operate from a single power supply between 4.5 V and 30 V, and a selection of models allows you to optimize the current output level for your application. The linear bipolar controller drives a Peltier thermoelectric cooler or a resistive heater, and the chassis-mount package integrates easily into OEM applications. PTC-CH controllers interface with a variety of temperature sensors, and the bias current is adjustable in order to maximize controller sensitivity and stability for your application.The compact chassis-mount design simplifies heatsinking and requires minimal space. PTC-CH controllers are quick to configure for your prototype project, and there are no surprises when it's time to integrate the controller into the final design.Practical Features For Real-World Conditions Built-in features make your product more robust to real-world operating conditions and minimize your electronics overhead: If the optional remote temperature setpoint signal is lost, the controller defaults to a standard "safe" temperature setpoint (25ºC when a 10 k© thermistor is used). The safe temperature can be changed at the factory; call for details. An on-board trimpot is used to set the output current limit to prevent over-driving the TEC, and helps protect your load from thermal runaway situations. Proportional gain is easily adjusted with an on-board trimpot. Low temperature coefficient design remains stable across a wide range of ambient conditions. When used with Wavelength's laser drivers, such as the PLD Series, these temperature controllers provide stable and reliable performance that sets your system apart from your competitors' and keeps your customers satisfied.
