The input AC power supply voltage is first rectified into DC, then converted into a high-frequency switching signal by a power transistor. This signal undergoes voltage conversion and electrical isolation via a high-frequency transformer. After secondary rectification and filtering, a stable 24V DC output is generated. The feedback control circuit continuously monitors the output voltage and adjusts the switching operation to maintain precise voltage regulation and efficient power conversion.
This module is designed for harsh industrial environments:
1. Protection Rating: IP20, suitable for DIN rail mounting (NS 35).
2. Safety Standards: Compliant with CE, cULus (UL 508) certifications, and multiple classification societies including ABS and DNV.
3. Short Circuit Protection: Integrated electronic short circuit protection with automatic restart function.
