产品特点 FEATURES

1 Modular design with 6 slots, supporting up to 1200W total output power (NMP1K2 model)

2 Compatible with NMS-240 (single output:5V/36A,12V/20A,24V/10A,48V/5A) and NMD-240 (dual output:30V/5A each) modules, offering flexible voltage and current configurations

3 Complies with medical safety standards (2x MOPP isolation between primary and secondary) and ITE standards, suitable for medical and industrial applications

4 Equipped with multiple protection functions: overvoltage protection (OVP), overcurrent protection (OCP), overtemperature protection (OTP), overload protection (OLP)

5 Supports global ON/OFF control (via RC1 pin) and local ON/OFF control for individual modules (via RC2/RC3 pins), with open state for ON and short state for OFF

6 Current sharing function for parallel operation of NMS-240 modules, ensuring balanced load distribution (total output current ≤ sum of rated currents of parallel modules, total power ≤1200W)

7 Provides DC OK signal (TTL level) to indicate module output status and T-Alarm signal for overtemperature warning

8 Wide input voltage range: AC 90-264V, DC 120-370VDC, adapting to various power grids

9 High power factor: PF>0.95 at 230VAC full load, PF>0.98 at 115VAC full load, reducing grid harmonic interference

10 Remote sense function (+S/-S pins) to compensate voltage drop on load wiring up to 0.5V, ensuring stable output voltage at load end

11 Auxiliary power outputs:5V/2A (front-end) and5V/10mA (per module), for external control circuits

12 Adjustable output voltage range for modules (e.g.,5V module:3-6V,12V module:6-15V, etc.), meeting customized voltage needs

使用场景 APPLICATIONS

1 Medical equipment: Suitable for devices requiring medical-grade isolation (like patient monitoring systems, diagnostic instruments) due to 2x MOPP compliance

2 Industrial automation: Power supply for PLCs, sensors, actuators, and control panels that need multiple DC voltage outputs

3 Test and measurement instruments: Provides stable, adjustable DC power for lab equipment (oscilloscopes, signal generators) with varying voltage requirements

4 Telecommunications: Supports rack-mounted systems (like routers, switches) needing multiple voltage levels and reliable power

5 Data centers: Modular power solution for server racks or storage systems requiring flexible power distribution

6 Embedded systems: Used in custom-designed electronic systems that need scalable DC power outputs

7 Rack-mounted applications: Fits standard rack setups, ideal for industrial or commercial environments needing high-power modular power

注意事项 PRECAUTIONS

1 Installation: Ensure AC terminal mounting torque is ≤12Kgf-cm and DC terminal ≤10Kgf-cm to prevent loose connections and overheating

2 Global ON/OFF Control: If not using remote control, install the shorting connector (RC1 pin to GND-P pin) to enable power output

3 Remote Sense: Use twisted-pair wiring for +S/-S pins to minimize electromagnetic interference and ensure accurate voltage compensation

4 Parallel Operation: For NMS-240 modules in parallel: connect CS pins of all modules; keep output voltage difference between modules <0.2V; total power must not exceed1200W; do not use PC (current programming) function

5 Derating Requirements: When output voltage <12V and ambient temperature is -15°C to -30°C, derate output current to90% of rated value. Follow derating curves for high ambient temperatures (e.g., reduce load at temps above50°C)

6 Local ON/OFF Control: For module-level control, ensure RC2 (NMS-240) or RC2/RC3 (NMD-240) pins are in correct state (open=ON, short=OFF) relative to GND

7 Connector Compatibility: Use HRS DF11 series connectors for control pins to ensure reliable electrical contact and mechanical stability

8 Auxiliary Power Limits: Do not exceed maximum load current for auxiliary outputs (5V/2A for front-end,5V/10mA per module) to avoid damage

9 Temperature Management: Ensure proper airflow around the unit to maintain ambient temperature within -30°C to +70°C; overtemperature protection will shut down output if internal temp exceeds limits

10 Safety Compliance: Use only Meanwell-approved modules and accessories to maintain safety standards and avoid equipment failure
