产品特点 FEATURES

1 Modular 6-slot design: Front-end unit supporting up to 1200W total output power, compatible with NMS-240 (single output, max 240W per module:5V/36A,12V/20A,24V/10A,48V/5A) and NMD-240 (dual output, max combined240W per module:0~30V each channel, up to5A) modules.

2 Flexible control options: Global ON/OFF (via RC1 pin, short for ON, open for OFF) and local ON/OFF for individual modules (via RC2/RC3 pins, open for ON, short for OFF) to meet different application needs.

3 Advanced monitoring and programming: Remote sense (compensates wiring voltage drop up to0.5V via +S/-S pins), output voltage programming (PV pin adjusts voltage within module's range) and current programming (PC pin adjusts current to40~100% of rated value), DC OK signal (TTL level:4.5~5.5V for ON,0~0.5V for OFF) and T-Alarm signal (indicates internal over-temperature).

4 Parallel operation support: Current sharing (CS pin) allows parallel connection of multiple NMS-240 modules, with up to6 modules in parallel (total power ≤1200W), ensuring balanced current distribution.

5 Comprehensive safety protections: Overload (constant current limiting or shutdown), overvoltage (shutdown, re-power to recover), over-temperature (shutdown, auto-recover after cooling) protections; complies with medical (EN60601-1 Ed.3.1) and ITE (EN62368-1) safety standards, with2x MOPP isolation between primary and secondary.

6 Wide environmental adaptability: Input voltage range of90~264VAC/120~370VDC, working temperature of-30~+70°C (with derating), and EMC compliance (EN55032, EN61000 series) for stable operation in harsh environments.

7 Auxiliary power outputs:5V/2A auxiliary power (5V-AUX-P) for external devices, and5V/10mA auxiliary power (Vcc2) per NMS-240 module for control circuits.

使用场景 APPLICATIONS

1 Medical equipment: Power supply for diagnostic instruments (e.g., blood analyzers), patient monitors, and laboratory devices requiring medical safety compliance (2x MOPP isolation).

2 Industrial automation: Used in PLC systems, industrial robots, control panels, and factory automation equipment needing scalable and stable modular power.

3 Test and measurement: Ideal for R&D test benches, electronic measurement instruments, and prototype development setups requiring adjustable voltage/current outputs and multiple channels.

4 Telecommunications: Supports telecom infrastructure like routers, switches, and base station components needing reliable, high-power modular power with monitoring capabilities.

5 Data centers: Powering server peripherals, storage systems, and network equipment requiring scalable power solutions and parallel operation.

6 LED lighting systems: Suitable for high-power LED displays, street lighting controllers, and indoor lighting systems needing multiple voltage outputs and stable power delivery.

注意事项 PRECAUTIONS

1 Installation safety: Ensure proper grounding via FG pin; use M3.5 screws (max penetration depth10mm, torque ≤10Kgf-cm) for output terminals and M4 screws (torque ≤12Kgf-cm) for AC input terminals.

2 Temperature management: Derate output current by10% when ambient temp is-15~-30°C and output voltage <12V; follow derating curves for temps above50°C to avoid overheating.

3 Module usage: Fill empty slots with BLANK-NMS240 blank modules to maintain thermal efficiency; only use compatible NMS-240/NMD-240 modules designed for NMP series.

4 Control operation: For global ON/OFF, install the shorting connector (RC1 to GND-P) if not using external control; ensure correct open/short logic for local module control (RC2/RC3 pins).

5 Parallel connection: When paralleling NMS-240 modules, connect CS pins together, ensure output voltage difference <0.2V between modules, and use short, thick wiring for parallel connections to minimize voltage drop.

6 Protection recovery: For overvoltage/overload protection, re-power the unit to recover; for over-temperature protection, wait until the unit cools down to restart.

7 EMC compliance: Use shielded cables for control signals (PV/PC/CS/DC OK) to reduce electromagnetic interference; follow installation guidelines to meet EN55032/EN61000 EMC standards.
