产品特点 FEATURES

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

2 Wide input voltage range: 90-264VAC or 120-370VDC

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

4 Flexible module options: Single output (NMS-240:5V/36A,12V/20A,24V/10A,48V/5A) or dual output (NMD-240: two 30V/5A channels, combined 240W)

5 Multiple protection functions: Overvoltage (OVP), overcurrent (OCP), overtemperature (OTP), overload (OLP) with shut-down or constant current limiting modes

6 Rich control features: Global/local ON/OFF control, remote sense (compensates up to 0.5V line drop), voltage programming (PV), current programming (PC), DC OK signal (TTL level indicating output status), temperature alarm (T-Alarm)

7 Parallel operation support for NMS-240 modules: Current sharing (CS) function to balance load between parallel modules

8 Auxiliary power outputs: 5V-AUX_P (2A for NMP1K2) and Vcc2 (5V/10mA for NMS-240 modules)

9 Complies with MEAN WELL's quality standards and safety requirements (e.g., 2x MOPP isolation for medical applications)

使用场景 APPLICATIONS

1 Industrial automation: Powering PLCs, sensors, actuators, and control systems requiring multiple DC voltages

2 Medical equipment: Suitable for devices needing isolated, stable power outputs (compliant with medical isolation standards)

3 Test and measurement: Flexible power supply for R&D labs and testing facilities to provide adjustable DC voltages

4 Telecommunications: Supporting network devices (routers, switches, transceivers) with diverse power requirements

5 Data centers: Modular power distribution for server racks and IT infrastructure

6 Broadcast and media: Powering cameras, mixers, and other professional equipment with multiple voltage needs

7 Laboratory setups: Ideal for experiments and prototyping requiring customizable DC power outputs

注意事项 PRECAUTIONS

1 Installation: Ensure proper mounting (follow screw torque specifications) and maintain adequate ventilation according to the air flow direction

2 Global ON/OFF: The shorting connector (RC1 to GND-P) must be installed; otherwise, the power supply will have no output

3 Remote Sense: Use twisted pairs for sense lines (+S/-S) to minimize interference; this function compensates for voltage drop on load wiring up to 0.5V

4 Voltage/Current Programming: Follow the specified voltage ranges for PV (e.g.,3-6V for 5V module) and PC (1.8-6V) to avoid damaging the modules

5 Parallel Operation (NMS-240):

6 Connect CS pins and GND pins of all parallel modules

7 Ensure output voltage difference between modules is less than 0.2V

8 Max 6 modules in parallel; total power must not exceed 1200W

9 Use short, thick wires for parallel connections to reduce resistance

10 Remote control must turn all parallel modules on/off simultaneously

11 Do not use the PC (current programming) function when modules are in parallel

12 Temperature Management:

13 Derate output current to 90% of rated value if the output voltage is below 12V and ambient temperature is between -15°C and -30°C

14 Respond promptly to T-Alarm (overtemperature signal) by cooling down the device or reducing load

15 Wiring: Use appropriate wire gauge for input/output terminals; strictly follow pin assignments to prevent short circuits

16 Module Handling: Fill blank slots with BLANK-NMS240 to maintain safety and cooling efficiency; do not mix incompatible modules
