产品特点 FEATURES

1 Modular design: NMP1K2 front-end (6 slots) supports up to6 NMS-240 output modules, enabling flexible configuration of output voltages (5V/36A,12V/20A,24V/10A,48V/5A) via C/E/H/K code modules.

2 Wide input range:90~264VAC or120~370VDC, compatible with global power systems.

3 High efficiency: Up to91% (when using H/K modules at24V/48V nominal voltage full load), reducing energy consumption and heat.

4 Medical-grade safety: Complies with ANSI/AAMI ES60601-1 Ed.3.1, UL62368-1, EN60601-1, and IEC62368-1 standards;2x MOPP isolation between primary and secondary ensures safe use in medical/industrial scenarios.

5 Rich control functions: Remote ON/OFF (global/local), remote sense (compensates up to0.5V voltage drop), output voltage programming (PV pin), output current programming (PC pin), DC OK signal (module output status), T-Alarm (over-temperature warning), current sharing (module parallel operation).

6 Comprehensive protection: Over-temperature (auto-recovery), over-voltage (shut down, re-power to recover), overload (constant current limiting), earth leakage (<400uA@264VAC), touch current (<100uA@264VAC).

7 Auxiliary power: Front-end provides5V/2A auxiliary output; each NMS-240 module offers5V/10mA auxiliary power for external controls.

8 Compact size: Front-end dimensions 250×127×41mm (L×W×H), output modules118.5×37.9×18mm, saving installation space.

注意事项 PRECAUTIONS

1 Installation: Ensure shorting connector (RC1 to GND-P) is installed for global ON/OFF control; use M4 screws for front-end mounting (12Kgf-cm torque) and M3.5 screws for output terminals (10Kgf-cm torque, max penetration depth10mm).

2 Parallel operation: Connect CS pins of modules; keep output voltage difference <0.2V between modules; max6 modules for NMP1K2; avoid PC function in parallel mode; use short/thick wires to minimize voltage drop.

3 Temperature derating: When output voltage <12V and ambient temp is-15°C~-30°C, derate current to90% of rated; follow derating curves (e.g., at50°C ambient, reduce load to~70% for230VAC input).

4 Remote sense: Use twisted-pair cables for +S/-S lines to compensate voltage drop up to0.5V; ensure correct connection to avoid errors.

5 Protection handling: Over-voltage shutdown requires re-powering to recover; over-temperature shutdown auto-recovers when cool; overload uses constant current limiting (resumes normal after overload removal).

6 Safety: Operate within specified ranges; keep away from moisture/dust; ensure proper grounding to prevent electric shock.

7 Maintenance: Regularly inspect for loose connections, overheating, abnormal noise; replace faulty modules promptly.
