VueMetrix Inc. (Martinsried/Munich, Germany) has released a new product line of temperature controllers that features a switch mode DC/DC converter with smoothing filters to improve power conversion efficiency.

The operating point of the Vue-TEC-15 and the Vue-TEC-24 temperature controllers is regulated automatically. Vue-TEC 15 is rated at 120 Watts and the Vue-TEC 24 is rated at 200 Watts.

An auxiliary second serial port on the Vue-TEC allows it to communicate internally with another controller, combining seamlessly with other models in the VueMetrix line.

Like all VueMetrix products, the Vue-TEC is microprocessor controlled and features advanced fault diagnostics, user-settable operational limits, and an extensive library of interface commands. Either RS-232, USB or both can be used to interface with the controller, which can also run stand-alone or in conjunction with the WinVue user interface program. It is available in packaged form or as a circuit board assembly. A Developer's Kit is available that includes the controller, all necessary connectors, a power supply and WinVue software.

Designed to drive Peltier effect devices (thermoelectric coolers or TECs), the new controllers deliver precise temperature regulation of small thermal loads such as laser diode and heat sinks, non-linear laser crystals and infrared detectors. The VueMetrix complete product lines are available from AMS Technologies.
