The WTC3243 is a compact, analog PI (Proportional, Integral) control loop circuit optimized for use in ultrastable thermoelectric temperature control applications. It easily handles variable operating conditions with a stability of better than 0.0009 ºC. The temperature setpoint is set by a remote voltage signal. It is capable of controlling both thermoelectric and resistive heaters, and only five external resistors are needed to optimize the controller for your specific application. The WTC3293 Evaluation Board is available to quickly integrate the WTC3243 into your system and can be optimized for sensor type. Use the adjustable trimpots to configure heat and cool current limits, proportional gain, and integrator time constant. The robust and reliable WTC3243 has been designed into electro-optical systems, airborne instrumentation, spectroscopic monitors, and medical diagnostic equipment. It is particularly well-suited to applications where temperature is scanned across ambient. Key Features Linear PI Control Stability of 0.0009°C Heat and Cool Current Limits Adjustable Sensor Bias Current Drive ±2.2 A of TEC or Resistive Heater Current Small Size of 1.3" X 1.28" X 0.313" Supports Thermistors, RTDs, and IC Sensors Single Supply Operation: +5 V to +30 V 14-pin DIP PCB Mount Monitor Actual Temperature Quickly and easily integrated with WTC3293 Evaluation Board

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 Ω 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. Key Features Drive up to ±2.5, ±5.0, or ±10.0 A of linear bipolar TEC or heater current Add a booster unit to drive up to ±20.0 A Single supply operation: 5 to 30 VDC Small package: 3.0" x 3.2" x 1.1" Use a wide variety of temperature sensors Remote Output and Setpoint controls Short term stability: 0.0012°C Long term stability: 0.002°C Selectable sensor bias current Adjustable current limit Failsafe Setpoint default in case of remote temperature setpoint signal error

Output Current LD 2.2, 3 A; PCB Mount; Compatible with Type A, B & C Lasers Wavelength Electronics’ WLD33ND series of component type general-purpose laser diode drivers are easy-to-use analog circuits for space constrained laser diode applications. WLD33ND laser diode drivers maintain precision laser diode current (Constant Current mode) or stable photodiode current (Constant Power mode) using electronics that are compatible with any laser diode type. The WLD33ND series is the new version of the discontinued WLD3343 series of laser diode drivers. There are five laser diode driver models available in the WLD33ND series. While the standard WLD33ND provides up to 2.2 A to the laser diode, the WLD33ND-3A version provides up to 3 A. WLD33ND-2L and WLD33ND-3L are lower noise versions for constant current mode of the 2.2 and 3 A models, respectively. The WLD33ND-HB is designed to operate with lower voltage supplies, including 3.6 V for lithium-ion batteries. The WLD33ND series delays and slowly ramps the current for maximum protection. Safely supply up to 3 A of current (model dependent) to a laser diode from a single +5 V power supply. An internal thermostat shuts down the WLD33ND safely if the device temperature exceeds +105 °C. Heatsinking solutions to use the WLD33ND at full current are available. Remotely enable or disable current. Zero leakage current allows operation with VCSELs. Current range is scaled by an external resistor. Use the WLD33ND-EV Evaluation Board to rapidly prototype a complete laser diode control system with the WLD33ND laser diode driver. Onboard switches, connectors, and trimpots make the configuration and operation simple. Input and output cables are also included with the WLD33ND-EV. 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!
