产品特点 FEATURES

1 Modular design with 6 slots (NMP1K2 model) supporting up to 1200W total output power

2 Wide input voltage range: 90~264VAC or 120~370VDC, compatible with global power grids

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

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

5 Multiple output module options: single output (NMS-240:5V/36A,12V/20A,24V/10A,48V/5A) or dual output (NMD-240: two 30V/5A channels)

6 Flexible control functions: global ON/OFF (via RC1 pin) and local ON/OFF (per module via RC2/RC3 pins), remote sense (compensates up to 0.5V voltage drop), output voltage/current programming (PV/PC pins)

7 Protection mechanisms: overload (constant current limiting), overvoltage (shut down and re-power to recover), overtemperature (automatic recovery after cooling)

8 Parallel operation support: current sharing (CS pins) for balanced load distribution, up to 6 modules in parallel (total power ≤1200W)

9 Auxiliary power outputs: front-end 5V/2A, module-level 5V/10mA for control circuits

10 DC OK signal (TTL level) to indicate module output status, T-Alarm signal for overtemperature warning

11 Operating temperature range: -30~+70°C (with appropriate derating for low/high temps)

注意事项 PRECAUTIONS

1 Installation: Use M4 screws with mounting torque of 7~10 Kgf-cm; fill blank slots with BLANK-NMS240 accessory to ensure safety and airflow

2 Derating guidelines:

3 For output voltage <12V and ambient temp between -15°C and -30°C: reduce output current to 90% of rated

4 Follow derating curves for ambient temperature and input voltage (e.g., 230VAC only for certain conditions)

5 Global ON/OFF control: If not using, install the provided shorting connector (RC1 to GND-P) to enable output

6 Parallel operation:

7 Connect CS pins of all modules; ensure output voltage difference between modules <0.2V

8 Total output power must not exceed 1200W; max 6 modules in parallel

9 Do not use current programming (PC) function when modules are in parallel

10 Remote sense: Use twisted pairs for +S/-S lines to minimize noise interference

11 Wiring: Use appropriate gauge wires for output terminals to avoid voltage drop; follow terminal torque specs (10 Kgf-cm for output terminals)

12 Safety: Ensure proper grounding to meet leakage current requirements (<400uA at 264VAC)

13 Over-temperature: Monitor T-Alarm signal to prevent damage; the unit shuts down automatically when overheated and recovers after cooling

14 Programming: Adhere to voltage/current programming ranges (PV:3~6V for5V module, etc.) to avoid abnormal operation
