## Description

The AC-DC switching power supply converts 90-265VAC into stable 24VDC, ideal for LED strips and 24V equipment, delivers up to 100W with high efficiency, has overtemperature, overcurrent and short circuit protections for safe operation, includes screw terminals for direct connection and dual output with two plus and two minus for quick powering of two consumers, without a housing.
AC-DC switching power supply module for converting mains voltage (90-265V AC) to a stable 24V DC voltage, with a maximum power of 100W. Designed to power LED strips, electronic devices and other 24V equipment, this module offers high conversion efficiency.
The module does NOT include the housing.
It is equipped with multiple protection functions, including over-temperature protection, over-current protection and short-circuit protection, ensuring safe and durable operation. It does not require additional connectors (connect the wires directly to the screw connectors) and is compatible with a wide range of electrical systems.
This power supply module is a switch mode power supply (SMPS). This type of power supply uses a switching circuit to efficiently convert alternating current (AC) voltage into a stabilized direct current (DC 24V), offering several advantages over linear power supplies.
The module has a dual output, meaning that for the 24VDC output there are two + and two -, which allow the attachment of two consumers in a more simplified way.
Specifications:
Input voltage: AC 90~265V, 50/60Hz
Output voltage: DC 24V
Output current: 4A (maximum 6A)
Output Power: 100W (144W Maximum)
Protections: Overtemperature, overcurrent, short circuit
Dimensions: 115 x 65 x 32mm
Use:
Make sure that the power source is compatible with the 90-265V AC range. Be very careful because you are working with AC mains voltage!
After connecting the power, test the output to ensure that the voltage and current are within optimal parameters.
Connect the input wires to the electrical network according to the pins marked AC Input . Polarity is not relevant.
Attach the 24V DC consumers to the output terminals, which are marked DC + and - .
Avoid overheating by mounting the module in a well-ventilated space.
Package Included:
1 x AC-DC 24V Power Supply Module
