Switching power supply ZI-2, input voltage 85-264V AC, output voltage 5, 12, 15, 18, 24, 48 V DC, P=50W, 6 modules

Universal switching power supply – a reliable energy source

This switching power supply is a versatile solution for powering a variety of electrical and electronic devices. It is suitable for both professional installations and home applications where a stable and filtered voltage is required. The design allows for mounting on a 35mm rail, making it easy to integrate with existing systems.

Designed to operate in an input voltage range of 85-264V AC, it ensures independence from mains voltage fluctuations. An output power of up to 50W and a current of 4A allow you to power a wide range of devices. Output voltage stabilization guarantees optimal operation of connected receivers, and a high switching frequency (70kHz) minimizes interference.

Construction and functionality

The power supply is characterized by a modular design – it occupies as many as 6 modules on the mounting rail. Made with attention to detail, it has screw terminals providing secure and durable wire connections (2.5mm²). The IP20 protection class protects against accidental contact, increasing safety.

It is worth noting the versatility of this model – thanks to the possibility of mounting on a rail, installation is quick and convenient. The power supply is adapted to work at temperatures from -10°C to 40°C, making it suitable for use in various environmental conditions. Additionally, overload protection (current limitation to 110% of the nominal value) protects both the power supply and connected devices.
