MEA-100B

Product catalog summary

Overview: The MEA-100B is a high-performance welding power supply designed for precision welding of small parts. It features an intuitive user interface and a compact, desktop footprint. The unit is CE certified, ensuring compliance with European safety standards.

Key Features:

Secondary Constant Current Control: Ensures stable current flow with feedback every half cycle, suitable for multi-cycle welding.
Single-Cycle and Half-Cycle Welding: Allows programming of first and second half waves separately for added precision in small parts welding.
Voltage Fluctuation Compensation: Adjusts current every half cycle to compensate for power supply voltage fluctuations.
Built-in Weld Monitor: Allows setting upper and lower limits to monitor weld quality.

Technical Specifications:

Power Requirements: Single phase, 200/220/230/240/380/400/460/480 VAC with auto-switch capability.
Maximum Output Capacity: Ranges from 60 kVA to 86 kVA depending on input voltage.
Control Methods: Includes secondary constant-current control and power supply voltage fluctuation compensation control.
Welding Current Accuracy: Maintains accuracy within +/- 2% against +/- 10% fluctuation of power supply voltage and load.
Timer Settings: Offers 31 schedules for various welding cycles and slopes.
Current Monitoring: Provides upper and lower limits for current settings with incremental adjustments.
External Communication: RS-485 bi-directional communication supported.
Operating Environment: Temperature range of 0°–45°C, humidity up to 90% (non-condensing), altitude up to 1000 meters.

Transformer Specifications: Various models available with different capacities, cooling methods, and dimensions. Options include air-cooled and water-cooled transformers with specific duty cycles and maximum welding currents.
