产品特点 FEATURES

1 Modular power supply design: NMP1K2 model with 6 slots, supporting up to 1200W total output power

2 Wide input voltage range: AC 90~264V or DC 120~370V, compatible with 47~63Hz frequency

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

4 Multi-standard compliance: Meets ITE (UL62368-1, EN62368-1) and medical (ANSI/AAMI ES60601-1 Ed3.1, EN60601-1 Ed3.1) safety standards; 2x MOPP isolation between primary and secondary

5 Comprehensive protection functions: Overload (constant current limiting), overvoltage (shutdown, repower to recover), overtemperature (auto-recover after cooling), short circuit (hiccup or constant current limiting for specific modules)

6 Flexible control options: Global/local ON/OFF control, remote sense (compensates up to 0.5V wiring drop), output voltage programming (PV pin), output current programming (PC pin), DC OK signal (TTL level), current sharing (for parallel operation), T-alarm (overtemperature signal)

7 Auxiliary power outputs: Front-end 5V/2A and module-level 5V/10mA

8 Compatible with NMS-240 single-output modules (e.g.,24V@10A (H) and48V@5A (K) as per model code)

使用场景 APPLICATIONS

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

2 Medical equipment: Suitable for devices requiring 2x MOPP isolation (e.g., diagnostic machines, patient monitors; verify device-specific compliance)

3 Telecommunications: Stable power supply for network switches, routers and base station peripherals

4 Test and measurement instruments: Adjustable and reliable power for lab testing setups

5 Data centers: Modular power solution for server racks or auxiliary equipment

6 Large-scale LED lighting systems: High-power and adjustable output for LED installations

注意事项 PRECAUTIONS

1 Installation: Use recommended M4 screws (7~10Kgf-cm torque) for front-end mounting; M3.5 screws (10Kgf-cm torque) for module terminals; ensure proper grounding via FG terminal

2 Operation:

3 Global ON/OFF: Install the shorting connector (RC1 to GND-P) if global control is not used; no output available without it

4 Local ON/OFF: For NMS-240 modules: open RC2 (pin3) to GND for ON, short for OFF; for NMD-240 dual modules: similar logic for RC2 (V1) and RC3 (V2)

5 Remote sense: Use twisted pairs for +S/-S lines to minimize noise; max compensation of 0.5V wiring drop

6 Parallel operation: Connect CS pins of all modules; ensure output voltage difference <0.2V between modules; total power ≤1200W; max 6 modules in parallel; do not use PC function in parallel

7 Derating: For output voltage <12V and ambient temp -15~-30°C, derate current to90% of rated; follow derating curves for high ambient temps

8 Safety: Avoid operating in flammable/explosive environments; disconnect input power before maintenance; do not touch live parts when powered on

9 Maintenance: Keep the unit dust-free; ensure unobstructed airflow as per marked direction
