产品特点 FEATURES

Modular design: 1200W maximum power, 6 slots for NMS-240 (single output) or NMD-240 (dual output) modules, supporting flexible output configurations.

Wide input range: 90~264VAC /120~370VDC, 47~63Hz, suitable for global use.

High efficiency: Up to 91% at full load with 24V/48V modules (H/K type), reducing energy consumption.

Multi-protection functions: Overload (shut down, re-power to recover), overvoltage (constant current limiting), over-temperature (auto-recover when cool), ensuring stable operation.

Rich control functions: Global/local ON/OFF control, remote sense (compensates up to 0.5V voltage drop), output voltage (PV) and current (PC) programming, DC OK signal (TTL level), current sharing (CS) for parallel operation.

Safety compliance: Meets medical (ANSI/AAMI ES60601-1 Ed3.1) and ITE (UL62368-1, EN62368-1) standards, with EAC TP TC004 certification.

Auxiliary power: Front-end provides 5V/2A auxiliary output; modules provide 5V/10mA auxiliary power.

Mechanical specifications: Dimensions 250×127×41mm, weight ~2kg, mounting with M4 screws (torque 7~10 Kgf-cm).

使用场景 APPLICATIONS

Medical equipment: Suitable for diagnostic devices (e.g., blood analyzers, ultrasound machines), patient monitoring systems, and other medically compliant devices requiring stable and safe power.

Industrial automation: Used in PLCs, industrial control panels, robotic systems, and test & measurement equipment that need modular and reliable power supplies.

Telecommunications: Supports network equipment, base stations, and small data centers with flexible power configurations.

Laboratory instruments: Ideal for analytical tools, research equipment, and precision devices that demand high-quality power with low ripple and noise.

Commercial professional devices: Applied in high-end audio/video systems, professional lighting, and other commercial equipment requiring efficient and modular power solutions.

注意事项 PRECAUTIONS

Installation:

1 Use M4 screws for mounting, with torque 7~10 Kgf-cm and maximum penetration depth of 4mm to avoid damage to the chassis.

2 Ensure proper grounding (FG) to meet safety requirements.

3 For control pins, use 20~26AWG wires with a strip length of 10mm for reliable connections.

Operation:

1 Global ON/OFF: If not using global control, assemble the shorting connector (RC1 to GND-P) to enable output.

2 Local ON/OFF: For NMS-240 modules, keep RC2 open for ON and short for OFF; for NMD-240 modules, keep RC2 (V1) and RC3 (V2) open for ON.

3 Remote Sense: Use twisted pairs for sense lines (+S/-S) to minimize interference; compensates up to 0.5V voltage drop on load wiring.

4 Parallel Operation:

5 Connect CS pins of all modules to ensure current balance; output voltage difference between modules must be <0.2V.

6 Maximum 6 NMS-240 modules for NMP1K2; total output power must not exceed 1200W.

7 Do not use the PC (current programming) function when modules are in parallel.

8 If load is <10% of rated capacity, some modules may enter standby mode.

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

Safety:

1 Follow all applicable safety standards (medical/ITE) during installation and operation.

2 Avoid overloading beyond the maximum 1200W capacity to prevent damage.

3 Ensure proper insulation between primary and secondary circuits (4KVAC isolation) is maintained.
