Rectified direct current source V-18.02 FN4 is intended to complete the spot, projection and seam resistance welding machines, and is also used as a heating source for soldering and parts preheating during metal forming.
The source is designed to operate under the following conditions:
in closed rooms, at cooling water temperature from +5°С to +25°С;
at ambient temperature from +1°С to +35°С;
at relative humidity not exceeding 80% at temperature + 25°С;
ambient air must not contain harmful gases, which can damage metals, coating materials and insulation.
The current source is designed as a monoblock unit, which consists of a three-phase welding transformer and a built-in six-phase rectifier power board. ABB 7110 A diodes 5SDD 71х0400 are installed one in each phase and used as rectifying devices. This monoblock unit is efficiently water cooled.
Advantages:
Compact design
Even phase load
High efficiency factor
High power factor
