Power Supply FF ZI-14 24VAC / 24VDC, 72W, 3A

FF ZI-14 is a switching power supply that delivers both 24VAC and 24VDC outputs with a maximum power rating of 72 W and a rated current of 3 A. It is intended for reliable low-voltage powering of control panels, sensors, relays and automation equipment. The unit’s compact format and dual-output capability allow integration into electrical cabinets and building or industrial automation systems where space and flexible voltage options are required.

Advantages

The power supply provides simultaneous 24VAC and 24VDC outputs from a single compact module, reducing the need for separate transformers and converters. Its switching topology improves efficiency and reduces heat generation compared with linear supplies, while the 72 W power capacity supports multiple small loads or a combination of control devices. The rated 3 A output current ensures stable operation for connected sensors and relays, and the enclosure is suitable for mounting inside electrical panels.

Suitable for

• Powering control panels and PLC auxiliary circuits
• Supplying sensors, detectors and measurement devices
• Feeding relays, contactors and low-voltage actuators
• Use in industrial automation racks and building management systems
• Installations where both 24VAC and 24VDC are required

Key specifications

• Output voltages: 24 VAC and 24 V DC
• Maximum power: 72 W
• Rated output current: 3 A
• Switching power supply topology for improved efficiency
• Compact enclosure suitable for electrical cabinet mounting

How to use

Install the FF ZI-14 in an appropriate electrical cabinet or mounting location following applicable electrical codes. Connect the AC mains input to the supply’s input terminals, observing correct polarity and protective earth connection where required. Route the 24VAC and 24VDC output terminals to the corresponding loads, ensuring total connected load does not exceed 72 W and individual current draw remains within the 3 A rating. Provide appropriate fusing or circuit protection on input and output lines as dictated by system design and safety standards.

Usage recommendations

Locate the unit with adequate ventilation and avoid mounting near heat sources. Verify compatibility of connected devices with 24VAC or 24VDC as applicable. For critical applications, include surge protection and consider redundancy or backup power arrangements to maintain system availability.
