III. Core Functions

1. Multi-channel Isolated Voltage Stabilized Output, High Redundancy and Reliability

As the core power supply unit of the control station, it outputs +5V (system logic), ±15V (analog I/O), +24V (digital I/O) four channels of isolated voltage stabilized power supply. The output has high precision and extremely low ripple, eliminating voltage fluctuation interference to control signals. It supports 2N redundant parallel connection. Two power supplies of the same model operate synchronously with equal current distribution, and seamless switching occurs when a single unit fails, with zero power interruption, ensuring the continuous operation of the DCS.

2. Wide-range Adaptive AC Input, Global Grid Compatibility

Supports an ultra-wide range of 100–240VAC input, frequency 47–63Hz, automatically identifies 110V/120V or 220V/240V grids, no need for manual switching, compatible with global industrial power supply standards. The input side integrates an enhanced EMI filter circuit, effectively suppressing grid surges, spike pulses, and electromagnetic interference, significantly improving stability in strong electromagnetic environments.

3. Multiple Industrial-Level Protection, Automatic Fault Protection

Built-in five protection mechanisms: overvoltage, overcurrent, short circuit, overtemperature, and reverse connection prevention: when output overload / short circuit occurs, it automatically limits current and shuts off, and recovers after the fault is resolved; when the ambient temperature exceeds 75°C, power reduction protection is activated, and when it exceeds 85°C, it automatically stops; input reverse connection design to avoid wiring errors and module burnout, providing comprehensive protection for the power supply and the rear-end controller, I/O card.

4. Hot Swap Design, Online Maintenance Without Shutdown

Supports full-function online hot swapping. During normal operation of the system, faulty power supplies can be directly plugged in and replaced without shutting down the control station or interrupting the production process, significantly reducing fault handling time and suitable for 24-hour continuous production conditions.

5. Intelligent Status Monitoring, Visualized Operation

The panel is equipped with high-brightness LED status indicator lights, clearly displaying normal (PWR OK), fault alarm (FAULT), overload (OVERLOAD), redundant synchronization (SYNC) and other states. Maintenance personnel can quickly identify the operation status and promptly troubleshoot potential faults.

6. Industrial-level Robust Design, Adaptability to Harsh Environments

Uses a high-strength aluminum alloy + steel composite shell, surface treated with anti-static and anti-corrosion coatings, capable of withstanding vibration of 5g (10–500Hz), impact of 15g (11ms), and adapting to high-temperature, high-dust, and strong-vibration environments. Optimized air ducts + intelligent temperature-controlled fans, with a 30% improvement in heat dissipation efficiency compared to G02, providing more stable operation under high-temperature full-load conditions.
