Profile: Sun Electronic Systems, Inc. is a manufacturer of environmental chambers. Our product line includes temperature, test, cycling & environmental chambers, process & temperature controllers, and temperature calibrators. Our LN2 / LCO2 cooled environmental chambers are available in sizes ranging from 0.37 to 6.16 cu ft of working volume. The chambers are supplied with a choice of two controllers, both providing local and remote control. The EC0x series of environmental chambers feature the TC01 controller which allows local and remote temperature, time, and cycling control. The CE approved EC1x and EC1xHA environmental chambers feature the TC10 controller, providing advanced features such as battery backed memory, user probe, & controlled ramping. Our retrofit temperature controller offers precise control over variables such as temperature, pressure, and humidity. The retrofit controller offers advanced programmability both from the front panel and through remote interfaces, along with a wide range of operating and control functions to serve almost unlimited number of industrial and test applications. The controllers utilize the field proven PID control technique with user selectable co-efficients to accurately control the process. The controllers are equipped with safety features such as failsafe input, software selectable upper and lower process limits, open/short sensor detection, & hardware watchdog. We also specialize in applications that involve in complex temperature cycling programs, all of which are covered by the EC series environmental chambers. The PC series process controllers allow precise control and monitoring of factors such as temperature, humidity, vibration, and pressure.
