Switching stabilizer ZI-13, input voltage 10÷28V AC, output voltage 5, 12, 18, 24V DC, I=3A

Switching power supply – reliable power for your devices

Are you looking for a stable and efficient power supply for your electrical and electronic devices? The ZI-13 switching power supply is a solution that provides filtered output voltage, independent of voltage fluctuations in the mains. It will be useful in applications requiring precise and stable power supply.

This model is distinguished by its versatility – it offers the possibility of selecting the output voltage (5V, 12V, 18V, 24V DC) while maintaining a constant current of 3A. Thanks to this, you can easily adapt it to the needs of a specific device. The ZI-13 stabilizer is particularly useful where sensitive electronics require protection against interference and irregularities in the power supply network.

Construction and application

ZI-13 is a switching power supply designed for mounting on a DIN rail. Its design allows for connecting both alternating voltage (10÷28V AC) and direct voltage (pulse or filtered). It is worth remembering that in some cases, especially with sensitive receivers (e.g. radio receivers, microprocessors), it is recommended to use an additional input filter – consisting of an inductively compensated choke (2× 5÷15mH) and a capacitor (C= 0.33÷1μF). Such a solution will further improve the power supply quality and ensure optimal operation of connected devices.

The secondary voltage values can be adjusted to your needs: 18V DC is one of the available choices. The device operates in a temperature range from -10 to 40°C, which makes it suitable for most standard working conditions. The rated power of the stabilizer is 54 VA, and its housing provides IP20 protection. The screw terminals used allow connection of wires with a cross-section of up to 4.0 mm².
