产品特点 FEATURES

1 Modular design with 6 slots for flexible output configuration (supports single-output NMS-240 and dual-output NMD-240 modules)

2 Wide input voltage range: AC90~264V, DC120~370V, suitable for global applications

3 High efficiency up to 91% (full load with H/K modules at 24V/48V nominal voltage)

4 Multiple protection functions: Overload (OLP), overvoltage (OVP), overtemperature (OTP) protection; OTP shuts down output and recovers automatically when temperature normalizes

5 Medical and ITE safety compliance: Meets ANSI/AAMI ES60601-1 (2x MOPP isolation), UL62368-1, TUV EN60601-1, EN62368-1, IEC60601-1, IEC62368-1, EAC TP TC004 standards

6 Remote control capabilities: Global ON/OFF (via RC1 pin) and local ON/OFF (via RC2/RC3 pins for modules)

7 Remote sense function: Compensates voltage drop on load wiring up to 0.5V (NMS-240 modules)

8 Current sharing: Supports parallel operation of up to 6 modules for higher current output, with <0.2V voltage difference requirement between modules

9 DC OK signal: TTL level signal (4.5~5.5V ON,0~0.5V OFF) indicating module output status

10 Temperature alarm: T-Alarm TTL signal (high when over temp limit, low when normal) for overtemperature monitoring

11 Auxiliary power outputs: 5V/2A (NMP1K2 front-end) and 5V/10mA (module Vcc2) for control circuits

12 Low ripple and noise: Max 100~250mVp-p depending on module type and voltage

13 Compact mechanical design: NMP1K2 front-end dimensions 250×127×41mm (L×W×H), easy to integrate into equipment

使用场景 APPLICATIONS

1 Medical equipment: Diagnostic devices (ultrasound, blood analyzers), patient monitors (complies with medical safety standards)

2 Industrial automation: PLC systems, robotics, control panels (needs stable modular power)

3 Test and measurement: Lab instruments requiring precise voltage/current outputs

4 Telecommunications: Base stations, network switches (wide input range and high reliability)

5 LED lighting: High-power LED arrays with multiple voltage requirements

6 Data centers: Server racks or network equipment needing modular power solutions

7 Renewable energy: Inverters or charge controllers (supports wide DC input range)

注意事项 PRECAUTIONS

1 Installation: Use M4 mounting screws with torque 7~10 Kgf-cm for NMP1K2 front-end; ensure proper grounding and follow mechanical specs for mounting depth

2 Module management: Blank slots must be covered with BLANK-NMS240 accessories; only use compatible NMS-240/NMD-240 modules

3 Temperature derating: When output voltage <12V and ambient temp is -15°C~-30°C, derate output current to 90% of rated value; follow derating curves for different conditions

4 Parallel operation: Ensure output voltage difference between modules <0.2V; total power ≤1200W for NMP1K2; use short large-diameter wires; do not use PC function in parallel mode

5 Remote control: Install the shorting connector (RC1 to GND-P) if not using external global ON/OFF control; local ON/OFF requires proper connection of RC2/RC3 pins

6 Cooling: Maintain proper airflow as per the unit's airflow direction; do not block ventilation slots

7 Safety: Do not modify the product; operate within specified temperature (-30°C~+70°C) and humidity (20~90% RH non-condensing) ranges

8 Wiring: Use appropriate wire gauge for input/output connections to avoid voltage drop and overheating; follow pin assignments correctly for control and power terminals
