Efficient and Protected 24 V DC Power for Industrial Automation
The Finder 78.36.1.230.2402 converts a compatible AC or DC input supply into a regulated low-voltage DC output using high-frequency switch mode technology. Its flyback converter incorporates quasi-resonant zero-voltage switching to support efficient power conversion. The integrated potentiometer allows the output voltage to be adjusted from 24 to 28 V DC, enabling the supply to be configured for compatible equipment within its rated operating limits.
For protection against abnormal operating conditions, the power supply incorporates an integrated input fuse, internal thermal protection, varistor overvoltage protection and hiccup-mode short-circuit protection. During a short circuit, the hiccup protection system periodically attempts automatic recovery until normal operation can resume.
The power supply also supports suitable redundant arrangements using external OR-ing diodes. Finder identifies the 78.36 range as suitable for selected lead-acid battery charging applications, including compatible standard and gel batteries, subject to the battery manufacturer's charging requirements and the power supply's electrical characteristics.
