产品特点 FEATURES

1 Modular power supply design: NMP650 (4 slots, max 650W) and NMP1K2 (6 slots, max1200W) front-end units, compatible with NMS-240 (single output, up to240W) and NMD-240 (dual output, up to240W total) modules.

2 Wide input range: 90~264VAC or120~370VDC; frequency range47~63Hz.

3 High efficiency and power factor: Up to91% efficiency (for H/K modules at24V/48V full load); PF>0.95@230VAC full load, PF>0.98@115VAC full load.

4 Comprehensive protection: Overload (OLP: constant current limiting), Over Voltage (OVP: shut down, re-power to recover), Over Temperature (OTP: shut down, auto-recover when temp drops).

5 Safety compliance: Meets IEC/EN60601-1 (medical,2xMOPP isolation), IEC/EN62368-1 (ITE), and other regional safety standards.

6 EMC compliance: Emission (EN55032/EN55011 Class B), immunity (EN61000 series: ESD level4, RF field level3, EFT/Burst level3, Surge level4, etc.).

7 Advanced functions: Remote sense (compensates up to0.5V wiring drop), voltage programming (PV), current programming (PC), DC OK signal (TTL level for output status), current sharing (CS for parallel operation), global/local ON/OFF control, auxiliary power outputs (5V-AUX_P:2A for NMP1K2,1.5A for NMP650; Vcc2:5V/10mA for modules)

使用场景 APPLICATIONS

1 Medical equipment: Suitable for devices requiring medical safety standards (IEC60601-1), like diagnostic instruments, patient monitors.

2 Industrial automation: Powering PLCs, sensors, actuators in factory automation systems.

3 Telecom and data centers: Providing stable power for routers, switches, and server components.

4 Test and measurement: Used in lab setups needing precise voltage/current control and multiple outputs.

5 Parallel operation systems: For applications requiring higher power (up to650W/1200W) via parallel module connection.

6 Remote monitoring systems: Leveraging DC OK and T-Alarm signals for real-time status tracking.

7 Custom output configurations: Mixing single/dual modules to meet diverse voltage requirements in a single unit

注意事项 PRECAUTIONS

1 Installation: Use M4 screws (torque7-10Kgf-cm) for front-end mounting; M3.5 screws (torque10Kgf-cm) for output terminals; ensure proper grounding to FG.

2 Temperature derating: For output voltage <12V and ambient temp -15~-30°C, derate current to90% of rated; reduce load as per derating curves for higher ambient temps.

3 Parallel operation: Connect CS pins of modules; output voltage difference between modules <0.2V; total power ≤650W (NMP650) or1200W (NMP1K2); max parallel slots:4 (NMP650) or6 (NMP1K2); use short/large diameter wires; do not use PC function in parallel mode; remote control must sync all parallel modules.

4 ON/OFF control: Assemble shorting connector (RC1 to GND-P) if global control not used; global control via RC1-GND-P (short=ON, open=OFF); local control via RC2/RC3-GND (open=ON, short=OFF).

5 Remote sense: Use twisted pairs for +S/-S lines to minimize noise; compensate up to0.5V wiring drop.

6 Programming: PV/PC functions are referenced to module GND; follow specified voltage ranges for programming.

7 Protection: If OTP triggers, wait for temp to drop; for OVP/OLP, re-power on after fixing load/voltage issues.

8 Auxiliary power: Do not exceed max current for auxiliary outputs (5V-AUX_P:2A/1.5A; Vcc2:10mA)
