产品特点 FEATURES

Modular power supply with 6 slots (NMP1K2 model), supporting up to1200W total output power.

Configured with multiple12V (E code,20A/240W), one24V (H code,10A/240W), and one5V (C code,36A/180W) single-output modules (per EEEHCE configuration).

Wide input voltage range: AC90-264V or DC120-370VDC, suitable for global use.

High power factor: PF>0.95 at230VAC full load, PF>0.98 at115VAC full load, reducing grid interference.

Efficient performance: Up to91% efficiency at full load (with H/K modules at24V/48V), minimizing energy loss and heat generation.

Comprehensive protection: Overvoltage (shut down, re-power recovery), overcurrent (constant current limiting), overtemperature (auto shut down and recovery after cooling), overload (shut down, re-power recovery) protections.

Flexible control: Global/local ON/OFF, remote sense (compensates up to0.5V wiring drop), output voltage programming (PV pin), output current programming (PC pin).

Monitoring capabilities: DC OK signal (TTL level indicating output status), T-Alarm signal (overtemperature warning).

Safety compliance: Meets ITE (UL62368-1, EN62368-1) and medical (ANSI/AAMI ES60601-1 Ed3.1, TUV EN60601-1 Ed3.1) standards with2x MOPP isolation between primary and secondary; EMC compliant with EN55032 Class B (emission) and EN61000 series (immunity).

Parallel operation support: Allows up to6 NMS-240 modules in parallel for higher current output (with current sharing function), subject to total power limit.

使用场景 APPLICATIONS

Industrial automation systems: Powering PLCs, DCS, sensors, actuators, and control panels in manufacturing lines.

Medical devices: Suitable for diagnostic equipment (e.g., ultrasound machines), patient monitors, and lab instruments (compliant with medical safety standards).

Telecom and networking: Providing stable power to routers, switches, optical transceivers, and base stations.

Test and measurement setups: Adjustable output for lab equipment, component testing, and prototype development.

Data center infrastructure: Modular power for server racks, storage systems, and backup power units.

LED lighting applications: High-efficiency power for commercial LED displays, street lights, and indoor lighting systems.

Renewable energy integration: Converting DC power from solar panels or wind turbines to stable AC/DC output for various loads.

注意事项 PRECAUTIONS

Installation Notes:

1 Ensure proper grounding via the FG terminal to prevent electric shock and reduce electromagnetic interference.

2 Use recommended screw sizes: M4 for front-end mounting (torque:7-10Kgf-cm) and M3.5 for module DC terminals (torque:10Kgf-cm) to avoid loose connections and overheating.

3 Do not block the air flow direction (specified in mechanical specs) to ensure adequate cooling.

Operation Notes:

1 Do not exceed the total output power limit (1200W for NMP1K2) or individual module's rated power/current.

2 When using remote sense, use twisted-pair cables for sense lines to minimize noise; ensure the sense lines are connected to the load terminals directly.

3 For parallel operation:

4 Connect CS pins of all modules to enable current sharing; ensure output voltage difference between modules is less than0.2V.

5 Use short, thick wires for parallel connections to reduce voltage drop; do not use the PC (current programming) function in parallel mode.

6 Follow derating guidelines: When output voltage <12V and ambient temperature is between -15°C and -30°C, derate the output current to90% of rated value.

7 Global ON/OFF Control: If not using the global ON/OFF function, install the provided shorting connector (RC1 to GND-P) to enable output; otherwise, the unit will have no output.

Maintenance & Safety:

1 Always disconnect the power supply before performing maintenance or replacing modules to avoid electric shock.

2 Replace faulty modules only with compatible Meanwell NMS/NMD series modules to maintain safety and performance standards.

3 Do not operate the unit in humid, corrosive, dusty, or explosive environments; keep it in a well-ventilated area with ambient temperature between -30°C and +70°C (per derating curves).

4 Comply with local electrical codes and regulations during installation and operation.
