A power supply serves as an electrical apparatus that furnishes electric power to an electrical load. Its principal function is to transform electric current from a source into the appropriate voltage, current, and frequency required to energize the load. Hence, power supplies are alternatively referred to as electric power converters. This encompasses the Hi-Link Power Supply Module, SMPS (Switch-Mode Power Supply), and Power Adapter. While some power supplies exist as standalone equipment, others are integrated into the appliances they power. SMPS, or switch-mode power supply, is responsible for converting wall-voltage AC power into lower voltage DC power. Meanwhile, the Hi-Link Power Supply Module is a plastic-enclosed PCB-mounted isolated switching step-down power supply module. At Elecfy, we offer a wide array of power supply solutions to meet diverse needs and applications, ensuring reliable and efficient power delivery.
