The Sun Systems EC13-HA is a 3 ft³ environmental temperature testing chamber engineered for rapid thermal cycling in automated test and laboratory environments. It delivers 600 CFM vertical airflow with convection heating and supports an optional 200 CFM ambient air blower for enhanced cooling. The chamber operates from −184°C to 315°C with liquid nitrogen or −73°C to 315°C with liquid carbon dioxide, making it suitable for demanding thermal stress applications across semiconductors, electronics, and materials testing.
Technical Specifications
Thermal Performance
• Internal volume: 3 ft³
• Primary airflow: 600 CFM vertical with convection heating
• Auxiliary cooling blower: 200 CFM ambient air, 3.5-inch exhaust port
• Temperature range (LN2): −184°C to 315°C

Controller & Programming
The TC10 controller features non-volatile memory for storing temperature profiles and test parameters. A secondary probe monitors product temperature independently. Users program sequences via BASIC-like command syntax with menu-driven probe calibration and adjustable PID coefficients. Power-down restart capability preserves system state during interruptions.
Safety & Protection
• Mechanically or electronically adjustable over-temperature limit protection
• Open and short probe detection
• Processor watchdog timer
Electrical
Power requirement: 200–240 VAC
– Key Features
• Local control via full-function keyboard and 2-line 16-character LCD display
• Remote operation via IEEE-488 (GPIB) or RS232/RS422 serial interfaces
• Analog and auxiliary I/O for external device integration
• Up to 5 open collector ON/OFF outputs (outputs 0, 1, 7 reserved for HEAT, COOL, FAN)
• Transparent IEEE-488 to RS232/RS422 bridge communication
– Typical Applications
Rapid thermal cycling for component qualification, reliability screening, thermal shock testing, and automated production test environments.
– Compatibility & Integration
The EC13-HA integrates with IEEE-488 and RS232/RS422 networks for remote monitoring and control. Commands govern chamber setpoint, ramp rates, soak duration, deviation limits, and temperature thresholds. Weight: 138 lbs.
