| NEW -- PTC PCB Series PRECISION TEMPERATURE CONTROLLERS
Practical, Powerful and Easy-to-Use PCB-Mount Control
TIME-TESTED RELIABILITY
The PTC Series PCB-Mount Temperature Controllers are based on our long-proven PTC-CH controllers, and deliver the stable performance and long-term reliability you expect from Wavelength Electronics.
PTC Series controllers are found in such diverse applications as particle and droplet measurement, communications, manufacturing test, and medical systems.
POWERFUL AND EASY-TO-USE
The PTC controllers operate from a single power supply between 5 V and 30 V, and two models drive ¡¾5 amps or ¡¾10 amps to a Peltier thermoelectric cooler or a resistive heater. These controllers mount directly to your circuit board.
PTC 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.
You can use the PTCEVAL board to quickly configure the PTC controller for prototyping. Using the same controller for development and production helps guarantee there are no surprises when it¡¯s time to release the final design.
PRACTICAL FEATURES FOR SAFETY AND VERSATILITY
Valuable features make your product more robust to real-world conditions and minimize your electronics overhead:
* Onboard controls, combined with the ability to remotely control the PTC allows maximum application versatility.
* Built-in heatsink and fan simplifies thermal management of the controller.
* If the remote temperature setpoint signal is lost, the controller defaults to a standard ¡°safe¡± temperature setpoint (25¨¬C when a 10 k¥Ø thermistor is used). The safe temperature can be changed at the factory; call for details.
* An onboard 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 onboard trimpot.
* Low temperature-coefficient design remains stable across a wide range of ambient conditions.

| PRECISION USB LASER DIODE & TEMPERATURE CONTROL
Leverage your low-noise, high-stability Wavelength Electronics laser control system with the budget-friendly USBKIT interface board and software package. The bus-powered USB 2.0 interface board is easily wired using on-board screw terminals and the QuickConnect™ virtual control panel provides out-of-the-box functionality with strip chart graphs that show real-time laser system status.
One laser diode driver and one temperature controller can be simultaneously operated with the USBKIT. Multiple USBKITs can be attached to the same computer, allowing for control of complex systems.
Factory-modified National Instruments multifunction I/O card includes D/A for remote setpoint control, and auxiliary A/Ds for increased versatility.
The software controls one laser diode driver, one temperature controller, and features graphing and data logging.
Setup configuration can be saved for repeating experiments or manufacturing testing.
The QuickConnect software includes on-screen wiring diagrams for the connected Wavelength modules, making set-up a snap.
Using the full-featured graphic user interface you can set the desired load temperature as a voltage or a temperature, maximum and minimum temperature limits can be established, as well as whether laser diode current is disabled if temperature limits are exceeded. Temperature sensor calibration is easy with the built-in resistance-to-temperature conversion functions.
The software provides control of the laser drive current in constant current mode, or photodiode current in constant power mode. Photodiode current is easily converted to laser output power, and the drive current limit is displayed on-screen.
Two strip charts graph data as a function of time. Raw voltages, as well as translated current and temperature values are available. One graph is associated with data from the temperature controller, and the other displays laser diode controller data. Auxiliary monitors can be associated with either graph, and all data can be logged whether it's displayed or not.
If your application requires additional functionality, program customization is available.
Wavelength Electronics has simplified advanced laser diode drive and thermal control technology for OEM and research applications since 1993. Our high performance specifications are supported by a team of experienced sales and design engineers and a state-of-the-art manufacturing facility.
