产品特点 FEATURES

1 Modular 1200W power supply with 6 slots for flexible output configuration (supports single-output NMS-240 and dual-output NMD-240 modules)

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

3 High energy efficiency: Up to 91% at full load (for H/K modules at 24V/48V nominal voltage)

4 Comprehensive protection mechanisms: Overload (constant current limiting), overvoltage (shut down & re-power to recover), overtemperature (auto-recover after cooling)

5 Advanced control functions: Global/local ON/OFF control, remote sense (compensates up to 0.5V wiring drop), output voltage programming (PV pin) and current programming (PC pin)

6 Real-time monitoring signals: DC OK (TTL level indicating output status), T-Alarm (overtemperature alert)

7 Parallel operation capability: Up to 6 NMS-240 modules can be paralleled with CS pins for current balance, maximizing power output while ensuring stability

8 Safety compliance: Meets ITE and medical safety standards (2x MOPP isolation between primary and secondary), with high isolation voltage (I/P-O/P:4KVAC, I/P-FG:2KVAC)

9 Compact and lightweight design: Dimensions of 250×127×41mm (L×W×H) and weight of ~2kg, easy to integrate into various systems

使用场景 APPLICATIONS

1 Industrial automation: Powering PLCs, sensors, actuators, and other devices requiring multiple voltage levels in production lines

2 Medical equipment: Suitable for low-risk medical devices (e.g., patient monitors, diagnostic tools) due to compliance with medical safety standards (note: verify with specific device regulations)

3 Test and measurement: Flexible voltage outputs for testing electronic components, circuits, and prototypes in labs

4 Data centers and telecom: Parallel operation provides reliable, scalable power for servers, switches, and communication equipment

5 R&D laboratories: Customizable power solutions for research projects needing adjustable voltage/current settings

6 Embedded systems: Integration into specialized equipment (e.g., industrial PCs, control panels) that demand modular and efficient power supply

注意事项 PRECAUTIONS

1 Installation: Ensure proper grounding via FG terminal; use M4 screws with torque of 7~10 Kgf-cm for mounting to avoid loose connections

2 Global ON/OFF: The shorting connector (RC1 to GND-P) must be installed if not using external global control, otherwise no output will be present

3 Remote sense: Use twisted-pair cables for +S/-S lines to reduce noise; do not exceed the 0.5V compensation limit

4 Parallel operation: Connect CS pins of all modules; ensure output voltage difference between modules is less than 0.2V; total power output must not exceed 1200W; maximum 6 NMS-240 modules can be paralleled; avoid using the PC (current programming) function when modules are in parallel

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

6 Protection handling: If overvoltage protection is triggered, re-power the unit to recover; overload protection will limit current to a safe level without shutting down

7 Wiring: Follow terminal assignments strictly (e.g., local ON/OFF: RC2 open = ON, RC2 short to GND = OFF)

8 Environmental conditions: Operate in a well-ventilated area with ambient temperature between -30°C and 70°C; avoid exposure to dust, moisture, or corrosive substances
