Chinfa AMR5-24 24V 4.2A DIN Rail Power Supply
A low-profile 100.8W industrial AC-DC power supply with universal input and a regulated 24VDC output.
The AMR5-24 converts a single-phase AC or compatible high-voltage DC input into a stable 24VDC supply for building automation and industrial control equipment. Its 4.2A output capacity makes it suitable for controllers, sensors, relays, actuators, communications equipment and other regulated 24VDC loads.
Typical Applications
- Building automation systems
- Industrial automation and machinery
- PLC and remote I/O systems
- HVAC controls and monitoring equipment
- Sensors, relays and actuators
- Security and access-control systems
- 24VDC control panels and instrumentation
Universal AC and DC Input
The AMR5-24 accepts a wide 90 to 264VAC input and can also operate from a 120 to 375VDC source, allowing use across common industrial and commercial power systems.
100.8W Regulated Output
The power supply delivers a nominal 24VDC output at up to 4.2A, providing 100.8W of continuous power.
Low-Profile Design
The 57mm-deep enclosure is designed for installations where panel depth is limited, making the AMR5-24 particularly suitable for building-automation cabinets and compact control enclosures.
High-Efficiency Operation
Typical efficiency of 89% helps reduce internal power losses and heat generation, supporting dependable natural-convection cooling.
Internal Input Filter
An integrated input filter helps reduce conducted electrical noise and supports reliable operation in control-system environments.
Integrated Protection
Built-in short-circuit protection helps safeguard the power supply and connected equipment during abnormal operating conditions.
