6 Protection functions: Overload (constant current limiting), overvoltage (shut down & re-power to recover), overtemperature (shut down & auto recover when temperature drops).

7 Control & programming: Global (RC1) and local (module RC2) ON/OFF control; remote sense (compensates up to 0.5V wiring drop); output voltage (PV) and current (PC) programming options.

8 Monitoring features: DC OK signal (TTL level,4.5~5.5V for ON,0~0.5V for OFF) for module status; T-Alarm signal (overtemperature indicator); LED indicators per module.

9 Parallel capability: Supports current sharing for NMS-240 modules (up to6 slots for NMP1K2) with voltage difference <0.2V between modules.

10 Auxiliary power: Front-end (5V/2A for NMP1K2), module-level (5V/10mA for NMS-240).

11 Mechanical specs: Dimensions (250x127x41mm LxWxH), weight ~2kg; mounting with M4 screws (7~10 Kgf-cm torque).

使用场景 APPLICATIONS

1 Medical equipment: Diagnostic devices (ultrasound, blood analyzers), patient monitors, laboratory instruments (complies with medical safety standards and 2x MOPP isolation).

2 Industrial automation: PLCs, DCS systems, industrial robots, control panels (modular design for flexible voltage/current config, wide input range).

3 IT & Telecom: Server racks, network switches, data centers (high efficiency, parallel capability for scalable power).

4 Test & Measurement: Electronic test benches, precision instruments (programming and monitoring features for accurate control).

5 Broadcast & Media: Professional audio/video gear, transmitters (reliable power with stable output).

6 Renewable Energy: Inverters, battery management systems (supports DC input range120~370VDC).

注意事项 PRECAUTIONS

1 Installation: Use M4 screws (7~10 Kgf-cm torque) for front-end mounting; M3.5 screws (10 Kgf-cm) for modules. Ensure proper airflow as per mechanical diagram.

2 Global Control: Install the shorting connector (RC1 to GND-P) if global ON/OFF control is not used; otherwise, no output will be present.

3 Local Control: For NMS-240 modules: open RC2 (pin3) to GND for ON, short for OFF. For NMD-240: separate RC2/RC3 controls for V1/V2.

4 Derating: When output voltage <12V and ambient temp is -15~-30°C, derate current to90% of rated value. Follow derating curves for temp and input voltage.

5 Parallel Operation: Ensure output voltage difference <0.2V between modules; total current ≤ sum of rated currents; max6 slots for NMP1K2; remote control must turn all parallel modules ON/OFF at once; PC function is disabled in parallel.

6 Wiring: Use twisted pairs for remote sense lines to reduce noise; use short, large-diameter wires for parallel connections to minimize voltage drop.

7 Safety: Comply with applicable safety standards (medical vs ITE) for the intended application; ensure proper grounding to avoid leakage current issues.

8 Protection Recovery: Overvoltage and overload require re-powering to recover; overtemperature recovers automatically when the device cools down.

9 EMC: Ensure proper shielding and grounding during installation to maintain EMC compliance.
