Testermeter-SCR-6-7-7E-220V 24V Power Supply 380-480vac AC Voltage RegulatorsStabilizers for SCR Three Phase Usage
Features
Wide-range input is compatible with three-phase AC input voltage 380-480V AC (universal for 50/60Hz), covering the common fluctuation range of industrial three-phase power grids (such as ±15% grid deviation). There is no need to manually switch the range, and it can be directly connected to the factory three-phase power line. Multi-output configuration provides two types of stable outputs: 220V AC output: It may be a single-phase or three-phase auxiliary power supply, used to drive peripheral equipment of the SCR main circuit (such as contactors, cooling fans, etc.). The output current is presumed to be of medium power level (e.g., 10-50A, which needs to match the auxiliary load of the SCR system). 24V output: It is most likely direct current (DC), serving as the control power supply for the SCR trigger circuit (such as power supply for pulse transformers and trigger boards). The output ripple is ≤1%, ensuring the stability of the trigger pulse (the current is presumed to be 1-5A, meeting the requirements of low-power control circuits). |
