The **SPM-7600AG** is a high-performance, medical-grade ATX power supply unit (PSU) manufactured by **Sinpro Electronics**. It is specifically designed to provide stable power for sensitive medical devices, high-end workstations, and industrial automation equipment. --- ### 1. Technical Specifications Overview The SPM-7600AG is characterized by its high wattage and compliance with medical safety standards (EN60601-1). | Feature | Specification | | :--- | :--- | | **Total Power Output** | 600 Watts | | **Form Factor** | ATX 12V / PS2 | | **Input Voltage** | 90 ~ 264 VAC (Universal Input) | | **Efficiency** | 80 PLUS Gold Equivalent (~87-90%) | | **Safety Standard** | ANSI/AAMI ES60601-1, EN60601-1 (3rd Edition) | | **MTBF** | >100,000 Hours | --- ### 2. Key Electronic Components & Design The internal architecture focuses on noise suppression and thermal management to ensure reliability in critical environments. #### A. Power Factor Correction (PFC) * **Active PFC:** It utilizes an active PFC circuit to ensure a power factor of >0.95. This reduces harmonic distortion and improves energy efficiency. #### B. Filtering and Protection Circuits To meet medical standards, the unit includes robust protection layers: * **EMI Filtering:** Enhanced multi-stage filtering to prevent electromagnetic interference with other medical diagnostic equipment. * **Protection Modules:** * **OVP (Over Voltage Protection):** Shuts down the unit if voltage exceeds safe limits. * **OCP (Over Current Protection):** Prevents damage from current spikes on individual rails. * **SCP (Short Circuit Protection):** Immediate latch-off during a short. #### C. DC Output Rails The unit distributes its 600W across multiple rails to support modern CPUs and peripherals: * **+12V Rail:** High amperage for processors and motors. * **+5V & +3.3V:** Dedicated DC-to-DC converters for stable logic voltage. * **+5Vsb:** Standby power for remote wake-up functions. --- ### 3. Medical Specific Features Unlike standard PC power supplies, the SPM-7600AG features: 1. **Low Leakage Current:** Designed to keep leakage current extremely low (typically < 300µA) to prevent electric shock to patients. 2. **2xMOPP Isolation:** (Means of Patient Protection) provides double insulation between the primary (high voltage) and secondary (output) sides. 3. **Dual Ball Bearing Fan:** High-quality cooling component to ensure a long lifespan under 24/7 operation. --- ### 4. Connector Configuration The unit typically comes with a standard medical/industrial wire harness: * **24-pin** Main Power * **8-pin (4+4)** 12V CPU Power * **SATA & Molex** for storage and legacy peripherals * **PCI-E 6+2 pin** for GPU or FPGA accelerators
