产品特点 FEATURES

1 Modular design with 6 slots for flexible output configuration (NMP1K2 model, 1200W max total power)

2 Wide input range: 90~264VAC or 120~370VDC, 47~63Hz frequency range

3 High efficiency: Up to 91% (full load with H/K modules at nominal 24V/48V)

4 Compliance with multiple safety standards: Medical (2x MOPP between primary and secondary), ITE (UL62368-1, EN60601-1 Ed3.1, etc.)

5 Rich protection functions: Overload (constant current limiting), overvoltage (shut down and re-power to recover), overtemperature (auto recover after temp drop)

6 Flexible control options: Global ON/OFF (via RC1 pin) and local ON/OFF (per module via RC2 pin), remote sense (compensates up to 0.5V wiring drop), voltage programming (PV pin), current programming (PC pin)

7 Parallel operation support: Current sharing (CS pin connection) for up to 6 modules, ensuring balanced load distribution

8 Auxiliary power output: 5V/2A (for NMP1K2) to power external control circuits

9 EMC compliance: Meets EN55032 (Class B) for emission, EN61000 series for immunity (ESD level4, surge level4, etc.)

10 Compact mechanical design: Dimensions 250x127x41mm, weight ~2kg, easy to mount with M4 screws

注意事项 PRECAUTIONS

1 Installation: Ensure the shorting connector is installed between RC1 (CN32-PIN6) and GND-P (CN32-PIN3) if global ON/OFF function is not used

2 Temperature derating: When output voltage <12V and ambient temp is -15~-30°C, derate output current to90% of rated value; follow derating curve for other conditions

3 Parallel operation: Max 6 modules for NMP1K2; ensure output voltage difference between modules <0.2V; connect CS pins mutually; total power not exceeding1200W

4 Remote sense: Use +S/-S pins to compensate for voltage drop on load wiring (max0.5V)

5 Programming functions: Follow guidelines for PV (voltage) and PC (current) programming to avoid damage; do not use PC function during parallel operation

6 Blank slots: Must install BLANK-NMS240 module in empty slots to maintain EMC and thermal performance

7 Over-temperature: Monitor T-Alarm signal (TTL level) to detect internal overheating

8 Mounting: Use M4 screws with torque7-10Kgf-cm; ensure proper airflow for heat dissipation
