产品特点 FEATURES

1 Modular power supply with 6 slots (NMP1K2 model) supporting up to 1200W total output; each module can be single (5V/36A,12V/20A,24V/10A,48V/5A) or dual output up to 240W

2 Wide input voltage range:90-264VAC or 120-370VDC, compatible with global power grids; frequency range 47-63Hz

3 High energy efficiency:Up to 91% (for 24V/48V modules at nominal voltage full load), reducing energy loss and heat generation

4 Comprehensive safety compliance:Meets medical standards (2x MOPP isolation between primary and secondary) and ITE standards (ANSI/AAMI ES60601-1 Ed3.1, UL62368-1, TUV EN60601-1 Ed3.1 etc.)

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

6 Rich functional options:Remote on/off control (global/local), remote sense (compensates up to 0.5V voltage drop), output voltage/current programming (via PV/PC pins), DC OK signal (TTL level for output status), current sharing (for parallel operation of modules)

7 Auxiliary power outputs:5V-AUX_P (2A for NMP1K2) for system use, and 5V/10mA per module (Vcc2) for control circuits

8 Compact mechanical design:Dimensions 250×127×41mm (NMP1K2), easy to install with specified mounting screws and torque

使用场景 APPLICATIONS

1 Industrial automation:Powering PLCs, sensors, actuators, and control panels requiring multiple stable DC voltage outputs

2 Medical equipment:Suitable for non-life-supporting medical devices (like diagnostic tools, patient monitors) due to medical safety compliance

3 Telecommunications:Supporting routers, switches, and base station components with varying DC voltage needs

4 Test and measurement:Used in labs for precise, adjustable power supply to instruments and prototypes

5 Data centers:Providing auxiliary power to server management modules and storage devices

6 Renewable energy systems:Interfacing with solar panels or batteries (wide DC input range) to power diverse loads

7 LED lighting:Powering high-power LED arrays with modular voltage configurations

注意事项 PRECAUTIONS

1 Installation:Ensure proper grounding of FG pin; use M4 screws (7-10Kgf-cm torque) for front-end mounting and M3.5 screws (10Kgf-cm torque) for output terminals to prevent loose connections

2 Derating requirements:Reduce output current when ambient temperature exceeds 50°C (follow derating curves); for output voltage <12V and temp between -15°C to -30°C, derate to 90% of rated current; total output power must not exceed 1200W (NMP1K2)

3 Parallel operation:Connect CS pins of modules for current sharing; ensure output voltage difference between parallel modules <0.2V; max 6 modules for NMP1K2; use short, thick wires for parallel connections; remote control must activate all parallel modules simultaneously

4 Control operations:Global on/off:Short RC1 (CN32 pin6) to GND-P (CN32 pin3) to turn on; local on/off:Short RC2 (module pin3) to GND for off, open for on

5 Wiring tips:Use appropriate wire gauge to minimize voltage drop; for remote sense, connect +S/-S pins to load terminals to compensate up to 0.5V drop

6 Environmental conditions:Operate in -30°C to +70°C (with derating), 20-90% RH non-condensing; avoid dust, moisture, and corrosive environments

7 Safety precautions:Do not exceed input/output ratings; disconnect power before maintenance; use only Meanwell-approved modules and accessories
