blog about New Power Modules Enhance Communication Network Stability

In the rapidly evolving landscape of communication technology, stable equipment operation forms the foundation of network reliability. However, power grid uncertainties, equipment overload risks, and harsh environmental conditions constantly challenge power system resilience. When power fluctuations or outages occur at critical moments, the resulting service disruptions and potential data loss can lead to immeasurable consequences.

The PAC600S12 series AC-DC power modules were engineered to address these challenges. With exceptional performance, comprehensive protection mechanisms, and intelligent communication capabilities, these modules provide reliable power solutions for communication equipment. Their wide input voltage range and multiple protection measures ensure stable operation under various complex conditions, making them indispensable components in communication infrastructure.

The PAC600S12 series integrates advanced technologies to deliver unparalleled performance and safety:

• Comprehensive Protection Mechanisms: Built-in safeguards include overcurrent protection, short-circuit protection, output overvoltage protection, and overtemperature protection. These features enable rapid response to unexpected current surges, short circuits, or overloads, preventing damage to connected equipment. The overtemperature protection ensures safe operation in high-temperature environments while extending module lifespan.
• Intelligent Communication: Supporting the I²C communication protocol, these modules facilitate real-time data exchange with control systems. Operators can monitor key parameters like output voltage, current, and power while receiving alarm notifications. This intelligent management simplifies troubleshooting and maintenance while enabling advanced power system monitoring and automated control.
• Hot-Swap Capability: The hot-swap design allows safe insertion or removal of power modules without system interruption—a critical feature for high-availability communication equipment that significantly improves maintenance efficiency and service continuity.
• Wide Input Voltage Range: With compatibility for 90-290Vac input, the modules adapt to diverse global power standards and fluctuations. They maintain stable operation across TT, TN, and IT power systems, ensuring continuous power delivery.
• 1+1 Redundancy: The 1+1 redundant backup configuration enables immediate failover when one module malfunctions, guaranteeing uninterrupted system operation—an essential solution for mission-critical applications.

The PAC600S12 series demonstrates excellence across technical parameters:

Delivering stable 12V output with maximum 600W power capacity, the modules maintain voltage between 11.64-12.36V. They feature excellent line regulation (±2%Vo) and load regulation (±3%Vo), ensuring precision voltage stability. Output ripple and noise (PK-PK) remain below 200mV, meeting stringent communication equipment requirements.

Operating within 90-290Vac range, the modules draw maximum 7.8A input current (at 220Vac, 600W output) while demonstrating excellent power factor performance for grid stability.

Input undervoltage protection activates at 90Vac with 85Vac cutoff and 5.0V hysteresis. Output overvoltage protection triggers between 13.5-16V using hiccup mode. Overcurrent protection engages at 52-60A (hiccup mode), while overtemperature protection activates at 70°C (E) or 60°C (B) with auto-recovery capability.

Operating temperature ranges from -25°C to 55°C, with storage tolerance from -40°C to 85°C—suitable for demanding industrial environments.

I²C communication enables reading of output parameters and electronic label information. The modules withstand ±6kV line-to-ground and line-to-line surges (IEC61000-4-5/ITU-T K.21 compliant) and achieve 0.25 million hours MTBF (Telcordia SR332 standard).

The series offers CE and CB certified variants—identical in core performance but differing in regional compliance. The CE variant suits European markets, while CB certification facilitates global deployment.

Clear pin definitions simplify system integration:

• 12V Output: P3 (12V+), P4 (12VGND), D2 (SHARE-12V), D3 (PG-12V)
• 3.3V & I²C: D4 (3.3V), D5 (I²C-SDA), D6 (I²C-SCL)
• I²C Configuration: C4 (A0), C5 (A1), C6 (Present), B4 (WP), B6 (A2)
• Alarm & Auxiliary: B2 (Alarm), B3 (3V3 Output)
• 48V Output (if applicable): A3 (SHARE-48V), A4 (PG-48V), P2 (48V-)
• Hot-Swap: A5 (PSKILL)

The compact design (90.0 × 195.5 × 22.3 mm) fits standard chassis and racks, featuring an IEC 60320 C14 input connector for convenient power cable connection.

The PAC600S12 series AC-DC power modules deliver robust performance, comprehensive protection, intelligent communication, and flexible hot-swap capability—providing stable, efficient power solutions for communication equipment. Whether supporting servers, routers, switches, or storage systems, these modules ensure continuous operation of critical services, empowering the advancement of communication networks.
