产品特点 FEATURES

1 Modular design with 4 slots (NMP650 model) supporting single-output (NMS-240) or dual-output (NMD-240) modules for flexible voltage/current configurations

2 Wide input range: 90~264VAC or 120~370VDC, compatible with global power grids

3 High efficiency up to 91% (full load with H/K modules at 24V/48V), reducing energy loss

4 Compliance with medical (2x MOPP) and ITE safety standards (ANSI/AAMI ES60601-1, UL62368-1, etc.)

5 Comprehensive protection: Overload (constant current limiting), overvoltage (shut down & repower recover), overtemperature (auto-recover)

6 Flexible control: Global ON/OFF (RC1 & GND-P) and local ON/OFF (per module via RC2/RC3 & GND)

7 Remote sense function: Compensates voltage drop on load wiring up to 0.5V

8 Output programming: Voltage (PV pin) and current (PC pin) adjustment for precise parameter control

9 DC OK signal: TTL level indicating module status (4.5~5.5V ON, 0~0.5V OFF)

10 Current sharing: Supports parallel operation (max 4 modules for NMP650) for balanced current distribution

11 Auxiliary power outputs: +5V-AUX-P (1.5A for NMP650) and Vcc2 (5V/10mA per module)

12 T-Alarm signal: TTL output for overtemperature alarm (high when over limit)

使用场景 APPLICATIONS

1 Medical equipment: Diagnostic instruments, patient monitors (compliant with medical safety standards)

2 Industrial automation: PLCs, sensors, actuators requiring multiple voltage outputs

3 Test & measurement systems: Lab tools, calibration devices needing stable/programmable power

4 Telecom/data communication: Rack-mounted setups with remote monitoring/control

5 Parallel operation: High-current applications like industrial motors or battery charging

6 Custom power solutions: Devices with diverse voltage needs (5V,12V,24V,48V) in one unit

注意事项 PRECAUTIONS

1 Use the shorting connector (RC1 to GND-P) if global ON/OFF control is not used; no output without it

2 Derating: When output voltage <12V and ambient temp -15~-30°C, derate current to 90% of rated value

3 Remote sense: Twist +S/-S lines to minimize noise

4 Parallel operation: Max 4 modules for NMP650; voltage difference between modules <0.2V

5 Parallel wiring: Use short/large-diameter cables; low load (<10% rated) may put some modules in standby

6 Overtemperature: T-Alarm high signal means over limit; cool the unit promptly

7 DC OK signal: Connect to GND for accurate status reading

8 Programming: Follow PV/PC pin guidelines to avoid damage

9 Safety: Do not open the unit; adhere to local safety regulations

10 Mounting: Use M4 screws (7~10 Kgf-cm torque) and ensure proper airflow
