EC127 Refrigeration Chamber
The EC127 refrigeration based temperature cycling chamber is a 2.7 ft3 , closed loop, refrigeration based, temperature controlled test chamber with an operating temperature range from -30°C to 200°C (-40C with optional cool boost). It was designed to provide a wide temperature test range for use in laboratory or production ATE or stand-alone product quality assurance and reliability testing. The chamber is cooled by its built in single stage environmentally safe vapor phase compressor system, and uses zero voltage controlled resistance heaters for heating the workspace. The EC127 is equipped with Sun Systems' advanced controller which provides precise temperature setpoint control (+/- .1°C) as well as many safety and user convenience features. The controller has user configured upper and lower temperature limits, open and shorted probe detection, hardware watchdog timer and an independent mechanically adjustable over temperature protection system. Some of the built in user features are GPIB, RS-232 and RS-422 remote interfaces, simple local programming with room for 10 local programs in battery backed RAM, and a second user probe located in the workspace for your use. Since Sun Electronic Systems designs and manufactures the complete unit, you can be sure that we stand behind the complete unit and that all of the chamber subsystems function together optimally.
CHAMBER CONSTRUCTION
The EC127 was designed to provide years of reliable service. The inner chamber is constructed of welded 304 stainless steel. The remainder of the cabinet is made of aluminum to resist rusting, and to make the chamber as light as possible, while still providing a strong, solid construction. The insulation system of the chamber has been designed to minimize thermal losses and insure safety. A dual centrifugal blower recirculation airflow system is employed to keep thermal gradients in the workspace to a minimum, and to quickly transfer heat to and from your device under test. The dual blower system provides greater than 300 ft 3 per minute of air circulation. The Model EC127 was designed for ease of service, should that be necessary. Both side panels are removable for total access to the refrigeration and electrical systems. All control electronics are mounted on the easily removable front control panel to allow for fast controller servicing. The chamber comes standard with a removable pull off door but can be ordered with a hinged door, with or without a window. Cable access ports can be ordered with the unit. The standard ports are 1", 2", 3" or 4" circular ports to be mounted on either the left or right side as well as the door.
