Embedded power supply 400W 12V 33.3A EPP-400-12

Switching power supply EPP-400-12 is a component designed to power devices requiring a stable 12V voltage. This model, with a power of 400W and an efficiency of 91.5%, finds application in industrial automation, control systems, and measurement electronics. The open frame design makes it ideal for embedding in device housings.

Characteristics and application

The EPP-400-12 power supply is characterized by a universal input voltage range and provides a stable 12V DC output voltage with a maximum current of 33.3A. Thanks to the use of PFC (Power Factor Correction), the power supply improves the power factor, which translates to more efficient energy use. Built-in protections – against short circuit (SCP), overload (OPP), overheating (OTP), and overvoltage (OVP) – guarantee safe and reliable operation. An additional, internal auxiliary power supply 12V/0.5A can be used to power control circuits or other low-power circuits.

Construction and mounting

Compact dimensions (127mm x 76.2mm x 35mm) allow for easy integration of the power supply into a limited space. Connection is made using 3.96mm raster plug connectors or screw terminals, which simplifies installation and ensures a secure electrical connection. The power supply is designed for mounting inside devices – this information is in the manufacturer's note. The low weight (0.39kg) further facilitates the installation process.

Safety and compliance with standards

The power supply meets the safety standards EN62368-1 and the EMC standards EN55032 class B, which guarantees its safe use and minimal impact on the electromagnetic environment. Thanks to this, it can be used in various industrial and commercial applications without fear of interference or electromagnetic compatibility issues.
