产品特点 FEATURES

Modular design with 6 slots (1200W max total power) for flexible output configuration using NMS-240 (single output) or NMD-240 (dual output) modules.

Wide input voltage range: 91-264VAC (47-63Hz) or 120-370VDC, suitable for global applications.

High efficiency up to 91% (for H/K modules at 24V/48V nominal voltage, full load).

Compliance with multiple safety standards: ANSI/AAMI ES60601-1 Ed.3.1, UL62368-1, TUV EN60601-1 Ed.3.1, EN62368-1, IEC 60601-1 Ed.3.1, IEC62368-1, TUV IEC60950-1, EAC TP TC004.

Comprehensive protection functions: Overload (constant current limiting or hiccup mode), overvoltage (shut down, re-power to recover), overtemperature (auto-recover after cooling), overcurrent.

Remote control and monitoring capabilities: Global/local ON/OFF control, remote sense (compensate wiring voltage drop up to 0.5V), output voltage/current programming (PV/PC pins), DC OK signal (TTL level for output status), T-Alarm signal (overtemperature alert).

Current sharing support for parallel operation of NMS-240 modules (up to 6 slots), ensuring balanced load distribution.

Auxiliary power outputs: 5V/2A (NMP1K2 front-end) and 5V/10mA (per NMS-240 module) for control circuits.

Robust mechanical design: Suitable for industrial environments with operating temperature range of -30°C to +70°C (with derating), vibration resistance (10-500Hz, 2G, 60min per axis).

注意事项 PRECAUTIONS

Derating guidelines:

a. When output voltage <12V and ambient temperature is between -15°C and -30°C, derate output current to 90% of rated value.

b. Follow derating curves for ambient temperature and input voltage (e.g., reduce load at higher temperatures or lower input voltages).

Installation:

a. Use recommended screw sizes (M4) with mounting torque of 7-10 Kgf-cm; avoid over-tightening.

b. Ensure proper airflow direction as per mechanical specifications to maintain cooling.

Parallel operation:

a. For NMS-240 modules, connect CS pins of all modules and ensure output voltage difference <0.2V between modules.

b. Total output power must not exceed 1200W; use short, large-diameter wires for parallel connections.

c. Remote control must turn ON/OFF all parallel modules simultaneously; avoid using PC (current programming) function in parallel mode.

Remote control setup:

a. If not using external global ON/OFF control, assemble the provided shorting connector (RC1 to GND-P) to enable output.

b. Local ON/OFF control for modules: Open RC2 (NMS-240) or RC2/RC3 (NMD-240) pins to turn ON, short to turn OFF.

Protection functions:

a. Overload/overvoltage: Power supply shuts down; re-apply input power to recover.

b. Overtemperature: Auto-recovers once internal temperature drops below the alarm threshold.

Safety compliance: Follow local electrical safety regulations and guidelines when installing and operating the power supply.
