Electronic enclosure with thermoelectric cooling unit now features programmable digital temperature control

EIC Solutions, Inc. now offers a digital temperature control (DTC) for fine-tuning of temperature inside air conditioned electronic enclosures. The DTC is fully programmable.

"Whereas our standard bimetallic thermostat meets the vast majority of customer needs," said Dave Bates, EIC operations manager, "some installations require tighter control over the internal enclosure temperature."

In these cases, Bates said the DTC provides a reliable means for highly accurate temperature regulation. Bates continued, "Digital control over interior cabinet temperature increases temperature accuracy and results in faster cooling cycles. This is essential in order to adequately protect certain types of electronics."

EIC digital temperature controls operate with a tolerance of +/- 1 degree Fahrenheit through the use of a proportional-integral-derivative (PID) control scheme. Essentially a control loop feedback mechanism, the PID controller dramatically increases accuracy in temperature regulation when compared to traditional thermostats which have a tolerance of +/- 4 degrees Fahrenheit.

Because DTCs are programmable, the customer can control internal enclosure environments over very specific temperature ranges and time periods. The use of a DTC also enables factoring in variables such as heat load fluctuations and power consumption resulting in more efficient and more effective cooling solutions.

Typically DTCs are mounted on the front panel of EIC air conditioned electronic enclosures. This permits easy access without requiring the enclosure to be opened. EIC can also mount DTCs in a variety of other configurations customizing the installation to meet specific customer needs. Also available is a remote monitoring and control option for installations where access to the digital temperature control on the enclosure is difficult. DTCs used in EIC units are NEMA 4 rated assuring the same level of protection and functionality as standard thermostat units while providing customers with a higher degree of accuracy.

Made in the U.S., EIC electronic enclosures and transit cases protect controls, computers, cameras, telecom equipment and other electronic/electrical gear from particulate contaminants, oils, water and most other environmental hazards. The weather-tight units are built to NEMA standards. Besides thermoelectric cooling units with DTCs, the enclosures are also available with a variety of other options including heaters, rain shrouds, drip pans and tamper resistant packages. Enclosures may be fitted with mounting feet, "drop-in" rack mount brackets, insulation or a polycarbonate view window.
