Product Features
Multi-Standard Compliance
The ZLT-LN1 meets four key international standards (IEC60335-1, IEC60950-1, IEC60601-1, IEC60065), making it suitable for testing appliances across industries (e.g., home appliances, medical devices, IT equipment).
Precise Force & Torque Control
Pull Force: Using calibrated weights (20N×2, 30N×2), the machine applies forces of 30N, 40N, 60N, or 100N without jerking—mimicking real-world stress on cords.
Torque: Torque weights (2.86N, 7.14N, 10N) deliver 0.1Nm, 0.25Nm, or 0.35Nm for 1 minute (standard), ensuring anchorages resist twisting damage.
Automated Data Recording
The 4-digit counter tracks the number of tension cycles (up to 9999) and torque duration, eliminating manual recording errors. It also automatically stops the drive when the preset test count is reached, improving efficiency.
User-Friendly Design
The control panel features clear buttons for start/stop, inching (for setup), and counter reset. The machine’s compact layout ensures easy sample loading and operation, even for novice users.
Application
The ZLT-LN1 is critical for scenarios where cord anchorage safety is paramount:
Home Appliance Manufacturing: Testing cord anchorages in vacuum cleaners, rice cookers, and electric kettles to prevent conductor damage from pulling or twisting.
Medical Device Industry: Verifying anchorages in infusion pumps, patient monitors, and surgical equipment—where cord failure could risk patient safety.
IT Equipment Production: Evaluating cords in laptops, printers, and servers to ensure durability during daily use (e.g., accidental cord pulls).
Cable Suppliers: Quality control for power cords, ensuring they work with appliance anchorages to meet IEC60335-1 and other standards.
FAQ
How many times is the pull test repeated?
Per IEC60335-1 Clause25.15, the standard pull test is repeated 25 times. The ZLT-LN1’s 4-digit counter automatically tracks cycles and stops when 25 is reached—no manual monitoring needed.
Can the machine test both pull force and torque in one sequence?
Yes. The machine first performs the 25-cycle pull test (without jerking, 1 time/second), then applies the specified torque (e.g., 0.1Nm) for 1 minute—matching the sequence required by international standards.
What happens if the cord shows strain during testing?
The test fails if the cord is damaged, shows appreciable strain at terminals, or displaces longitudinally by more than 2mm (when pull force is reapplied). The ZLT-LN1’s design ensures these issues are easy to observe.
Is the torque duration adjustable?
Yes. While the standard test duration is 1 minute (per IEC standards), the machine allows users to preset custom torque durations via the control panel—suitable for non-standard testing needs.
