Core Functions and Advantages
- Redundant power supply design: Supports 24V DC redundant input with an allowable input voltage range of 19.2 - 32.5 VDC. It meets the high availability requirements in industrial scenarios and ensures stable system operation even if a single power supply path fails.
- Stable output performance: Provides dual-channel output of 5 VDC / 5.5 A and 3.3 VDC / 6.5 A for the AC800F module. The output voltage accuracy reaches ±3% with low residual ripple, guaranteeing the stable operation of the controller and peripheral modules.
- Comprehensive protection mechanisms: Equipped with open-circuit protection, overload protection and continuous short-circuit protection. The short-circuit current is limited to approximately 7.5 A, and normal operation can be automatically restored after fault elimination, effectively protecting the module and downstream equipment.
- Power-off buffer capability: When the power supply is interrupted for ≥5 ms, a power-off signal is triggered and the output voltage is maintained stable for at least 15 ms. It can handle a total input voltage dip of 20 ms, ensuring safe system shutdown and restart.
- Status visualization: Real-time feedback of power supply status, system operation status and fault information through LED indicators, facilitating on-site rapid diagnosis and maintenance.
Key Technical Specifications
Application Scenarios and Compatibility
- Compatible devices: Specifically designed for the PM 802F / PM 803F base units of the AC800F controller, serving as the standard power supply component of the Freelance 800F control system.
- Application fields: Widely used in process automation control scenarios in industries such as power, chemical engineering, metallurgy, and environmental protection, especially suitable for small and medium-sized control projects with requirements for power supply stability and redundancy.
- Software compatibility: Must be used with Control Builder F V7.1SP2a or higher versions to ensure compatibility in system configuration and parameter management.
Installation and Maintenance Points
- Installation requirements: Must be used in conjunction with the PM 802F or PM 803F base unit. It is recommended to install it in a well-ventilated control cabinet to avoid electromagnetic interference and physical damage.
- Maintenance features: Supports hot-swap operation, allowing module replacement during system operation. The LED status indicators can quickly locate power supply faults, reducing maintenance downtime.
- Safety tips: It has no electrical isolation design. Industrial electrical safety specifications must be followed during installation and maintenance to avoid the risk of electric shock.
