Functional Characteristics
1. SIL3 Certified Dual Redundant Power Supply Architecture
Adopts hot standby dual redundant power supply design. Two independent power supply units operate simultaneously; one unit undertakes main power output, the other unit stands by. Single power supply unit fault triggers seamless automatic switchover to standby unit. The module achieves zero single-point power supply failure performance and maintains full SIL3 safety integrity.
2. Wide-range Universal AC Input Adaptability
Supports universal 85–264 V AC wide-range input, fully adapts global industrial grid voltage specifications. Stable output under large grid voltage fluctuation without additional voltage conversion equipment.
3. Complete Multi-level Safety Protection Circuits
Integrates input surge protection, output overvoltage/overcurrent/short-circuit protection, reverse polarity protection and temperature protection. Automatically cuts off abnormal output under fault conditions, completely protects backplane, CPU and all safety I/O modules from power damage.
4. High-performance Reinforced Galvanic Isolation Design
3000 V AC reinforced isolation between AC input grid side and DC output safety system side. Completely isolates industrial grid common-mode interference, lightning surge and electrostatic interference, ensures clean stable 24VDC power supply for safety control system.
5. Real-time Full-status Power Monitoring & Fault Alarm
Continuous online monitoring of input voltage, output voltage/current, internal temperature and circuit status. Automatically locates fault types, outputs dry contact alarm signals and uploads fault information to safety controller and HMI system, realizes transparent power supply health management.
6. Low Ripple High Stability Output Performance
Low ripple regulated DC output, fast dynamic response to load changes. Provides high-quality stable power supply for high-precision analog I/O modules and real-time safety logic CPU modules.
