产品特点 FEATURES

1 Modular front-end power supply (NMP1K2 model) with 6 slots, supporting up to 1200W total output power

2 Compatible with single-output modules (NMS-240:5V/36A,12V/20A,24V/10A,48V/5A) and dual-output modules (NMD-240: up to 30V per channel, combined 240W)

3 Complies with multiple safety standards including medical (ANSI/AAMI ES60601-1 Ed3.1) and ITE (UL62368-1) standards

4 Equipped with comprehensive protection functions: overload (O.L.P), over-voltage (O.V.P), over-temperature (O.T.P), and short-circuit (constant current limiting)

5 Supports flexible control functions: global/local ON/OFF, remote sense (compensates up to 0.5V voltage drop), output voltage programming (PV), output current programming (PC), DC OK signal (TTL level), current sharing (CS) for parallel operation, and T-Alarm for over-temperature

6 High efficiency up to 91% (typical at full load with H/K modules at 24V/48V)

7 Wide input voltage range: 90-264VAC or 120-370VDC

8 Low leakage current (<400uA at 264VAC)

9 Provides auxiliary power outputs:5V/2A for front-end,5V/10mA for modules

10 Supports parallel operation of modules with current balance (CS pin connection required)

使用场景 APPLICATIONS

1 Industrial automation systems requiring flexible power configurations

2 Medical equipment compliant with ES60601-1 standards

3 Test and measurement instruments needing multiple output voltages

4 Telecommunication and data center rack-mounted devices

5 Industrial control systems with varying power requirements

6 Laboratory equipment that requires adjustable output voltages/currents

注意事项 PRECAUTIONS

1 Ensure proper mounting torque:12Kgf-cm for AC input terminals,10Kgf-cm for DC output terminals

2 Use recommended screw sizes:M4 for mounting holes,M3.5 for DC output terminals

3 When using remote sense, correctly connect +S/-S pins to compensate for voltage drop on load wiring

4 For parallel operation: connect CS pins of modules, ensure output voltage difference <0.2V, total power ≤1200W, use short/large diameter wiring

5 Adhere to derating rules: for output voltage <12V and ambient temp -15~-30°C, derate current to90% of rated value; follow derating curves for temp and input voltage

6 Install shorting connector for global ON/OFF control if no external control is used

7 Do not exceed max load of individual modules or total system

8 Keep the unit in well-ventilated area to prevent overheating

9 Disconnect power before maintenance or module replacement
