产品特点 FEATURES

1 Modular design with 6 slots for NMP1K2, supporting up to 1200W total power; compatible with NMS-240 single output modules (5V/36A,12V/20A,24V/10A,48V/5A) and NMD-240 dual output modules (30V/5A each)

2 Wide input voltage range:90-264VAC or120-370VDC, suitable for global use; frequency range47-63Hz

3 High efficiency:Up to91% (typical) at full load when using H (24V) or K (48V) modules

4 Compliance with safety standards:Meets medical standards (2x MOPP isolation between primary and secondary) and ITE standards (ANSI/AAMI ES60601-1 Ed.3.1, UL62368-1, TUV EN60601-1, etc.)

5 Comprehensive protection:Overvoltage protection (OVP, shut down and recover on re-power), overload protection (OLP, constant current limiting), overtemperature protection (OTP, shut down and auto-recover after cooling)

6 Flexible control functions:Global/local ON/OFF control (open=ON, short=OFF for module RC2), remote sense (compensates up to0.5V voltage drop on load wiring), output voltage programming (PV) and current programming (PC) via external signals

7 Monitoring and auxiliary features:DC OK TTL signal (indicates module output status), T-Alarm signal (overtemperature alert),5V/2A front-end auxiliary power output,5V/10mA per-module auxiliary power

8 Parallel operation support:Current sharing (CS) function allows parallel connection of modules for higher current; ensure output voltage difference <0.2V between modules

注意事项 PRECAUTIONS

1 Installation:Use M4 screws for mounting with torque7-10 Kgf-cm; ensure proper airflow direction as per mechanical specifications to avoid overheating

2 Wiring:Follow correct pin assignments for input, output, and control signals; use appropriate wire gauge to minimize voltage drop and ensure safety

3 Load management:Do not exceed the total power limit (1200W) or individual module-rated currents; refer to derating curves for high-temperature operation (e.g., reduce output current to90% for Vo<12V at -15 to -30°C)

4 Remote control setup:For global ON/OFF function, install the shorting connector if not using the feature; ensure correct open/short connections for local module control

5 Parallel operation:Connect CS pins of all modules; ensure output voltage difference <0.2V between modules; do not use the PC (output current programming) function in parallel mode; use short, thick wires for parallel connections to maintain current balance

6 Environmental conditions:Operate within the specified temperature range (-30 to +70°C) and humidity (20-90% RH non-condensing); avoid exposure to dust, moisture, or corrosive environments

7 Safety:Disconnect power before performing maintenance or wiring changes; ensure proper grounding to prevent electric shock; avoid touching live parts when the device is powered on
