Description
ABB IPS21-35AD
Technical Specifications:
- Input/Output: Wide-range AC/DC input, standardized DC output.
- Protection Rating: IP20
Functional Features:
- Wide Voltage Adaptation: Accommodates industrial grid fluctuations while maintaining constant output.
- Multiple Protections: Built-in overvoltage, overcurrent, short circuit, and reverse polarity protection with auto-recovery.
- Low Ripple Output: Provides clean power for precision instruments and controllers.
Application Scenarios:
Used to provide localized power and signal matching for sensors, transmitters, small relays, and remote I/O stations.
Performance Parameters:
- Conversion Efficiency: > 85%, resulting in low heat generation.
- Hold-Up Time: Satisfies industrial system requirements for data retention during brief power drops.
Material Composition:
Internal high-frequency magnetic components and solid-state capacitors. Aluminum alloy or high-strength flame-retardant plastic housing provides both heat dissipation and shielding.
Structural Features:
DIN rail snap-on mounting with a front-panel power status LED and fuse holder for easy field maintenance.
Working Principle:
Utilizes advanced Switch-Mode Power Supply (SMPS) technology to convert input power through high-frequency inversion, transformer isolation, and rectification filtering to output stable low-voltage DC.
Installation Requirements:
Must be mounted vertically to facilitate natural convection cooling. Use appropriately sized conductors with crimped ferrules for input/output cables.
Usage Precautions:
Strictly prohibit overload operation. Always use identical specification fuses for replacements. Clean cooling vents regularly in dusty environments.
