Switching power supply zi-22 12V DC 2.5A ZI-22

Universal switching power supply for wide applications

This 30W, 12V DC, 2.5A switching power supply is a reliable energy source for a variety of devices and installations. It will work well in monitoring systems, home automation, and industrial applications. Its modular design allows for easy mounting on a 35mm rail, which significantly speeds up installation and configuration. The power supply is stabilized, which guarantees maintaining a constant output voltage regardless of fluctuations in the supply voltage and load.

Construction and functionality

Designed with durability and safety in mind, this power supply has short-circuit protection and IP20 protection class. Made of high-quality components, it ensures long-lasting and trouble-free operation. The type of electrical connection – screw/spring terminal – facilitates the connection of wires with a cross-section of up to 2.5mm². The width of the power supply, amounting to 3 modules (52.5mm), allows for effective use of space in the switchgear cabinet. The input voltage range of 100-264V AC (50/60Hz) makes it a universal solution, compatible with most electrical networks.

Key features and benefits

• Wide input voltage range: The power supply operates stably in the range of 100-264V AC, eliminating problems related to voltage fluctuations in the network.
• Output voltage stabilization: Guarantees precise and reliable power supply to connected devices, protecting them from damage caused by voltage changes.
• Short-circuit protection: Protects both the power supply and connected devices from the effects of a short circuit.
• Modular design: Enables easy mounting on a 35mm rail and flexible adaptation to various installation configurations.
• High efficiency: Ensures minimal energy losses and reduces operating costs.
• Universal application: Ideal for powering various electronic devices, such as CCTV cameras, alarm systems, building automation or LED lighting.
• Inrush current resistance: Allows for trouble-free starting of devices drawing a large starting current (e.g. light bulbs). In case of overload, the power supply attempts to start the load several times before shutting down.
• Compact dimensions: Allows mounting in a limited space – the depth is only 65mm and the height is 90mm.

Let's also remember the specifics of operation: below 160V input voltage, the output current may be limited due to the drop in input voltage. Due to the high operating frequency of the converter, it is recommended to use the OP-230 filter when connecting sensitive radio or microprocessor devices.
