产品特点 FEATURES

1 Modular design with 6 slots, supporting up to 1200W total output power

2 Wide input voltage range: 90~264VAC or 120~370VDC, adaptable to various power grids

3 High efficiency up to 91% (typical) at full load with H/K modules (24V/48V), reducing energy loss

4 Compliance with multiple safety standards: medical (2x MOPP between primary and secondary) and ITE standards (ANSI/AAMI ES60601-1, UL62368-1, etc.)

5 Comprehensive protection functions: overload protection (constant current limiting), overvoltage protection (shutdown and re-power recovery), overtemperature protection (automatic recovery after cooling)

6 Flexible control options: global ON/OFF (via RC1 and GND-P) and local ON/OFF (per module via RC2/RC3 and GND) for precise power management

7 Rich monitoring signals: DC OK signal (TTL level indicating module output status), T-Alarm signal (overtemperature warning), enabling real-time system monitoring

8 Current sharing capability for parallel operation of NMS-240 modules, ensuring balanced load distribution (output voltage difference <0.2V required)

9 Auxiliary power outputs: 5V/2A (NMP1K2 front-end) and 5V/10mA (per module), supporting external control circuits

注意事项 PRECAUTIONS

1 Installation: Follow recommended mounting torque (7~10 Kgf-cm for M4 screws), ensure proper airflow direction (as per mechanical specs) to prevent overheating

2 Derating guidelines: When output voltage is below 12V and ambient temperature is between -15°C to -30°C, reduce output current to 90% of rated value; refer to derating curves for temperature and input voltage conditions

3 Global ON/OFF setup: The shorting connector (from RC1 to GND-P) must be assembled for the power supply to output; remove it only when using global ON/OFF control

4 Remote sense usage: Connect +S/-S pins to load terminals to compensate for voltage drop on long wires (max 0.5V compensation)

5 Parallel operation: Ensure CS pins of all modules are connected; total output power must not exceed 1200W; output voltage difference between parallel modules should be less than 0.2V

6 Safety precautions: Properly ground the power supply; avoid overloading each module beyond its rated power (240W per NMS-240 module); do not use PC (current programming) function when modules are in parallel

7 Maintenance: Regularly check for dust accumulation to maintain airflow; inspect connectors for loose connections to prevent voltage fluctuations
