产品特点 FEATURES

1 Modular design with 6 slots, supporting up to 1200W total output power

2 Wide input range: 90~264VAC or 120~370VDC, compatible with 47~63Hz frequency

3 High efficiency: Up to 91% (typical) at full load with 24V/48V modules (H/K series)

4 Safety compliance: Meets medical (2x MOPP isolation) and ITE standards (ANSI/AAMI ES60601-1, UL62368-1, TUV EN60601-1 etc.)

5 Multiple protection mechanisms: Overload (constant current limiting), overvoltage (shut down, re-power to recover), over-temperature (auto shut down and recover after cooling)

6 Flexible output modules: Supports single-output (NMS-240:5V/36A,12V/20A,24V/10A,48V/5A) and dual-output (NMD-240: dual 30V/5A, combined 240W) modules

7 Remote control and monitoring: Global/local ON/OFF, remote sense (compensates up to 0.5V line drop), DC OK signal (TTL level), temperature alarm (T-Alarm) signal

8 Current sharing capability: Allows parallel operation of modules for higher current output (via CS pin connection)

9 Auxiliary power outputs: +5V-AUX_P (2A for NMP1K2) for system use and Vcc2 (5V/10mA) for module functions

使用场景 APPLICATIONS

1 Medical equipment: Diagnostic devices (e.g., ultrasound machines), patient monitoring systems, laboratory instruments requiring reliable and safe power

2 Industrial automation: PLCs, control panels, robotics systems needing multiple output voltages

3 Test and measurement: Electronic test equipment (e.g., oscilloscopes, power analyzers) that demands precise and flexible power supplies

4 Telecom and data communication: Network switches, routers, and communication devices requiring stable modular power

5 Other applications: Any system that needs customizable power outputs with high efficiency and safety compliance

注意事项 PRECAUTIONS

1 Installation: Use recommended screw sizes (M4 for front-end mounting, M3.5 for DC output terminals) and torque (12Kgf-cm for AC input,10Kgf-cm for DC output) to ensure secure mounting

2 Derating: When ambient temperature is between -15°C and -30°C and output voltage <12V, derate output current to 90% of rated value; follow derating curves for temperature and input voltage conditions

3 Global ON/OFF: Ensure the shorting connector (RC1 to GND-P) is assembled; otherwise, the power supply will have no output

4 Parallel operation: For module parallelism, connect CS pins of all modules, keep output voltage difference <0.2V between modules, total current ≤ rated per module × number of modules, and total power ≤1200W for NMP1K2

5 Remote sense: Use twisted pairs for sense lines to reduce noise; maximum voltage drop compensation is 0.5V

6 Environmental limits: Operate within -30~+70°C (derate above 50°C) and 20~90% RH non-condensing to avoid performance degradation

7 Protection recovery: Overvoltage protection requires re-powering to restore output; over-temperature protection auto-recovers once the internal temperature drops to safe levels
