产品特点 FEATURES

Modular design: 4-slot front-end (NMP650) supporting NMS-240 (single output) and NMD-240 (dual output) modules, enabling flexible voltage/current configuration for diverse load requirements.

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

High efficiency: Up to91% typical efficiency at full load (with H/K modules 24V/48V), reducing energy loss and heat generation.

Comprehensive safety compliance: Meets medical (2x MOPP isolation between primary-secondary) and ITE standards, including ANSI/AAMI ES60601-1 Ed3.1, UL62368-1, TUV EN60601-1 Ed3.1, EN62368-1, IEC60601-1 Ed3.1, IEC62368-1, TUV IEC60950-1, EAC TP TC004.

Multiple protection functions: Overload (O.L.P), Over Voltage (O.V.P), Over Temperature (O.T.P), Short Circuit (O.C.P) – protection modes include shut-down (re-power recovery) or constant current limiting.

Versatile control functions: Remote sense (compensates up to0.5V line drop), global/local ON/OFF (via RC1/RC2 pins), DC OK signal (TTL level indicating output status), temperature alarm (T-Alarm), voltage/current programming (PV/PC pins for NMS-240), current sharing (CS pin for parallel operation).

Mechanical specifications: Dimensions250×89×41mm (L×W×H), weight ~1.45kg, mounting with M4 screws (torque range:7~10 Kgf-cm), air flow direction as per design for effective cooling.

使用场景 APPLICATIONS

Industrial automation systems: Powering PLCs, sensors, actuators, and control panels requiring multiple DC voltage outputs.

Medical equipment: Suitable for diagnostic devices (e.g., ultrasound, blood analyzers), patient monitoring systems, and lab instruments (complying with medical safety standards).

Test and measurement setups: Flexible voltage/current configurations for testing electronic components, circuit boards, and prototypes.

Telecom and network infrastructure: Powering routers, switches, and communication devices with diverse power requirements.

Data center auxiliary systems: Providing customized power for server management tools, cooling control modules, and backup devices.

Laboratory R&D: Supporting research projects needing adjustable DC voltages and currents for experimental setups.

Industrial IoT devices: Powering edge computing nodes, smart meters, and remote monitoring systems with varying voltage needs.

注意事项 PRECAUTIONS

Installation precautions:

1 Ensure proper grounding via the FG terminal to prevent electric shock and interference.

2 Use M4 screws for mounting, adhering to the torque range of7~10 Kgf-cm; avoid over-tightening to prevent damage to the chassis.

3 Fill all unused slots with BLANK-NMS240 accessories to maintain safety, dust protection, and proper air flow.

Wiring guidelines:

1 Use appropriate wire gauge for input/output connections to minimize voltage drop and heat; refer to mechanical specs for wire range and strip length.

2 For remote sense function, correctly connect +S/-S pins to the load terminals to compensate for line voltage drop (up to0.5V).

Operational notes:

1 Do not exceed the total maximum output power of650W; ensure individual module power does not exceed their rated capacity (240W per NMS-240/NMD-240).

2 When using parallel operation (via CS pins), ensure the output voltage difference between modules is less than0.2V; total output current should not exceed the sum of rated currents of parallel modules (but must not exceed650W total).

3 Follow the derating curve: Derate output current/power at ambient temperatures above50°C; for output voltage <12V and ambient temperature between-15°C and-30°C, derate current to90% of rated value.

4 Use the provided shorting connector (RC1 to GND-P) if global ON/OFF control is not required; remove it only when using external control signals.

Safety warnings:

1 Disconnect AC/DC input power before performing any maintenance or wiring changes to avoid electric shock.

2 Do not operate the device in humid, corrosive, or dusty environments; ensure adequate ventilation as per air flow direction.

3 Avoid touching exposed components when the device is powered on; high voltage may be present in the input section.
