产品特点 FEATURES

1 1300 Watt AC to DC power-factor-corrected (PFC) power supply, converting standard AC mains to 12 VDC main output for intermediate bus architectures (IBA)

2 High efficiency up to 94.0% for energy-saving operation

3 Wide input voltage range:90-264 VAC, suitable for global applications

4 Active power factor correction to meet harmonic emission standards

5 Always-On 10 W standby output (3.3 V) for continuous auxiliary power

6 Hot-plug capability allowing replacement without system shutdown

7 Parallel operation with active current sharing for redundant power systems

8 Full digital control for circuit loop and power management

9 High density design:30.25 W/in³, compact form factor:321.5 x54.5x40 mm

10 Power Management Bus (PMBus) communication protocol for control, programming and monitoring

11 Fully protected against over-temperature (OTP), over-current (OCP), over-voltage (OVP), short-circuit (SCP)

12 4K Bytes of EEPROM for user information storage

13 2 Status LEDs (FAIL and OK) with fault signaling

14 Compliant with international safety standards: UL/CSA60950-1, IEC/EN60950-1; CE-Mark for European Low Voltage Directive (LVD)

使用场景 APPLICATIONS

1 High performance and reliability servers, routers, and network switches using intermediate bus architectures (IBA)

2 Redundant power systems in data centers and enterprise IT environments

3 Telecom equipment racks requiring compact, high-density power solutions

4 Enterprise networking setups needing hot-plug and parallel operation capabilities

5 Data storage arrays and cloud computing infrastructure

6 Industrial control systems with strict power reliability requirements

注意事项 PRECAUTIONS

1 This product is marked as "NOT FOR NEW DESIGN", please confirm compatibility before integration

2 Derate output power and over-current protection (OCP) when operating temperature ranges from45°C to60°C (refer to derating curves)

3 Do not repeat input-to-output electrical strength tests in the field as it may void warranty

4 Remote sense function: If remote sense is lost, outputs will revert to internal sense to limit voltage to ≤105% of nominal

5 Fan cooling: Speed is automatically adjusted by DSP based on power demand and temperature; can be overridden via I2C bus

6 Correct pin connections: PS_ON_L pin needs to be connected to signal ground (SGND) to turn on the main output; PS_KILL pin overrides other on/off signals

7 Current sharing: For parallel operation, connect the ISHARE pins of all units together

8 Standby output: The3.3V standby output remains on even when main output is off (unless AC is lost)

9 Operating limits: Follow storage temperature (-40~+85°C) and operational altitude (≤10,000 feet) guidelines

10 Safety compliance: Ensure installation follows relevant safety standards and local regulations; not suitable for nuclear, medical, or life support systems
