4 Compliance with IEC60601-1 (medical 2xMOPP) and IEC62368-1 safety standards

5 Multiple protection functions:Overload (OLP), Over Voltage (OVP), Over Temperature (OTP), Short Circuit (SCP)

6 Remote control capabilities:ON/OFF, voltage programming (PV), current programming (PC), remote sense (+S/-S)

7 Current sharing for parallel operation (up to6 modules for NMP1K2)

8 DC OK signal (TTL level) to monitor output status

9 Auxiliary power outputs:5V/2A (front-end) and5V/10mA (module)

10 Compact size:250×127×41mm

11 Working temperature range:-30°C to +70°C (with derating)

使用场景 APPLICATIONS

1 Industrial automation systems:Powering PLCs, sensors, actuators, and control panels

2 Medical equipment:Suitable for diagnostic devices, patient monitors, and lab instruments (complies with medical safety standards)

3 Telecommunications:Stable power supply for routers, switches, and communication modules

4 Test and measurement instruments:Providing precise and adjustable power for lab testing equipment

5 Data centers:Modular power for server racks, storage systems, and network devices

6 LED lighting systems:High-efficiency power for large-scale LED displays and commercial lighting installations

7 Renewable energy systems:Integration with solar/wind power converters and battery management systems

8 Railway and transportation:On-board power for control systems and auxiliary devices (within temperature range)

注意事项 PRECAUTIONS

1 Installation:Use M4 screws for mounting (torque range:7-10Kgf-cm); ensure proper grounding to prevent electric shock

2 Temperature management:Operate within -30°C to +70°C; derate output current at high temperatures (refer to derating curve:e.g., at +60°C load up to80% of rated current; for Vo<12V below -15°C derate to90% of rated current)

3 Wiring:Use appropriate wire gauge for input/output connections; twist remote sense lines (+S/-S) to reduce electromagnetic interference

4 Protection handling:In case of protection activation (OTP/OVP/OLP), power off the device, check load and environment, then restart after troubleshooting

5 Parallel operation:When paralleling modules connect CS pins together; ensure output voltage difference <0.2V between modules; total power ≤1200W for NMP1K2

6 Remote control:Local module ON/OFF:open RC2 (pin3) to turn on, short to turn off; global ON/OFF uses RC1 (front-end pin6)

7 Auxiliary power:Do not exceed max current of auxiliary outputs (5V/2A front-end,5V/10mA modules)

8 Safety compliance:Do not modify the power supply; use only Meanwell-approved modules and accessories

9 Storage:Store in dry environment (-40°C to +85°C,10-95% RH non-condensing)

10 Maintenance:Regularly clean dust to ensure airflow; inspect wiring connections periodically for looseness
