POWER SOURCE VTF24SZ Product Description

Overview

POWER SOURCE VTF24SZ is a VTF-SZ series single-output AC-DC switching power supply manufactured by ETA-SEI (Power Source), VTF24SZ is the complete model designation of this unit. The POWER SOURCE VTF24SZ converts AC input into stable 24V DC output with 15A rated current, 300W rated power, to supply power for PLC, sensors, solenoid valves and I/O modules in industrial control cabinets. This VTF24SZ switching power supply serves as a reliable ETA VTF-SZ series industrial power supply, widely used for cabinet power distribution in factory automation, marine equipment and process control systems of the ETA VTF-SZ series industrial power supply.

Features

This POWER SOURCE VTF24SZ supports selectable input range AC90-132V or AC180-264V, compatible with global single-phase power grids for the ETA VTF-SZ series industrial power supply. It is equipped with overcurrent protection, overvoltage protection and thermal shutdown protection to protect against load faults. The metal housing design provides good heat dissipation and EMC performance. The output voltage can be adjusted within ±10% range to match field requirements. The POWER SOURCE VTF24SZ is made in Japan, with low ripple noise and stable continuous running performance. This model is mainly supplied as spare replacement part for legacy automation equipment maintenance of the VTF24SZ switching power supply.

Specs

The POWER SOURCE VTF24SZ series: VTF-SZ AC-DC switching power supply. Rated output: 24V DC, 15A, 300W. Input range: AC90-132V / AC180-264V, 47~440Hz. Output adjustment: ±10% adjustable. Protection: OCP, OVP, OTP. Mounting: screw fixed installation. Protection rating: IP20. The POWER SOURCE VTF24SZ complies with industrial power supply standards and CE requirements as a VTF24SZ switching power supply.

Principle

POWER SOURCE VTF24SZ works by high-frequency switching conversion principle. The POWER SOURCE VTF24SZ rectifies and filters the AC input, then converts it into high-frequency alternating current through switching devices, and performs step-down, rectification and filtering to obtain stable 24V DC. The built-in control circuit monitors output voltage and current in real time to realize closed-loop regulation. When overcurrent, overvoltage or overtemperature occurs, the protection circuit automatically cuts off the output. The high-frequency switching structure of the ETA VTF-SZ series industrial power supply realizes efficient AC-DC power conversion.

Applications

This POWER SOURCE VTF24SZ is widely used in packaging machinery, conveyor systems, marine automation equipment, pump and fan control cabinets and general industrial control panels. It is applied for 24V DC power supply for PLC, sensors, relays and solenoid valves. It is used for spare replacement and retrofit of existing ETA Power Source power supply circuits. The POWER SOURCE VTF24SZ delivers dependable 24V DC power supply for industrial automation equipment as a proven VTF24SZ switching power supply.
