Product Description
Temperature Limiter Life Durability Test Bench
- Product Overview:
The temperature limiter life durability test bench is used to simulate the actual working conditions for life testing of single and double pole contacts / automatic and manual reset temperature limiters; this device uses a stepper motor to drive the slide rod action, allowing the test sample to contact and leave the heating block, achieving repeated heating and cooling cycles. Cooling is done by blowing cold air for rapid cooling. The air source treatment components should include a filter, pressure regulator, pressure gauge, etc.
- Standards Compliance:
This instrument complies with the requirements of standards GB14536.1-2008 and GB14536.10-2008.
I. Main Technical Parameters of the Equipment:
- Equipment Power Supply: AC 220V/50Hz, 5KW;
- Test Stations: 3 stations, independent heating control;
- Test Temperature Range: RT room temperature to 400℃;
- Display Accuracy: 0.01℃;
- Temperature Control Accuracy: ±0.5℃;
- Heating Rate: During performance testing, the temperature rise rate should not exceed 0.5K/min;
- Record the temperature value when the temperature controller operates during testing (with three independent temperature measurement points, thermocouple diameter 0.25mm, placed on the test sample);
- Test Action Rate: 5 to 40 times/minute (adjustable);
- Drive Mode: Stepper motor drive;
- Heating Protection: Solid-state conductor heating;
- Life Test Count: 0 to 9,999,999 times, the number of tests can be preset, and the test will automatically stop, alarm, and reset when the count is reached;
- Intelligent Judgment Function: When contacts stick, causing continuous connection or disconnection, an alarm will sound after reaching the set number of times;
- Cooling Method: Blowing for rapid cooling;
- Does not include test load, with interface, can be used with load cabinet;
- Control and Operation: PLC control, TFT LCD touch screen operation;
- Standard USB Interface: The touch screen has good human-machine interaction functions, capable of storing multiple test results (test count, test temperature, disconnection temperature value, recovery temperature value, etc.) to a USB drive, which can be transferred to a computer and opened with EXCEL for viewing or printing;
- Software Functions: Automatically find the temperature at which the test sample operates, display real-time temperature and time change curves for each station, automatically adjust coordinates, and simultaneously zoom and print various combinations of temperature and time curves, test reports, etc.; all curves and reports are automatically saved and can be queried through the system for all test curves and data.
- Overall Dimensions: W1240mm*D650mm*H1580mm.
II. Electrical Life Load Parameters:
- Electrical Life: The load cabinet is a cabinet structure, with the box made of pressed and sprayed iron plate, equipped with 4 wheels at the bottom for easy movement. The upper front of the box is the control panel, which is sandblasted and colored for durability;
- Power Supply: With ground wire, three-phase AC380V±10%/50Hz;
