产品特点 FEATURES

1 Modular design: 1200W capacity (NMP1K2) with 6 slots, supports mixing NMS-240 (single output, up to 240W) and NMD-240 (dual output, up to 240W total) modules

2 Wide input range: 90~264VAC / 120~370VDC, 47~63Hz frequency

3 High performance: Power factor >0.95 at full load (230VAC), typical efficiency up to 91% (with H/K modules at 24V/48V nominal)

4 Safety compliance: Meets ANSI/AAMI ES60601-1, UL62368-1, TUV EN60601-1, EN62368-1, IEC 60601-1, IEC62368-1, EAC TP TC 004 standards

5 Multiple protection functions: Overload (constant current limiting), overvoltage (shutdown and repower to recover), overtemperature (shutdown and auto-recover when cool)

6 Flexible control options: Global (RC1 pin) and local (module RC2/RC3 pins) ON/OFF control; remote sense (+S/-S) to compensate wiring voltage drop up to 0.5V; voltage programming (PV pin) and current programming (PC pin) for output adjustment

7 Monitoring signals: DC OK (TTL level, indicates module output status), T-Alarm (overtemperature signal), current sharing (CS pin) for parallel operation of modules

8 Auxiliary power outputs: 5V-AUX_P (2A for NMP1K2) for system use; Vcc2 (5V/10mA) for module control circuits

9 Mechanical specs: Dimensions 250×127×41mm (L×W×H), weight ~2kg; compatible with HRS DF11 series connectors

使用场景 APPLICATIONS

1 Industrial automation systems: Customizable voltage outputs for various sensors, actuators, and controllers

2 Medical equipment: Complies with medical safety standards, suitable for diagnostic devices, patient monitors, and laboratory instruments

3 Test and measurement instruments: Stable, adjustable power supply for component testing and prototype development

4 Data centers and telecommunications: Parallel operation capability for high-power, redundant power systems; remote monitoring and control for unmanned operation

5 Embedded systems: Modular design adapts to diverse voltage requirements of embedded boards and peripherals

6 Laboratory research: Flexible voltage/current programming for experimental setups needing precise power control

注意事项 PRECAUTIONS

1 Installation: Ensure the shorting connector (RC1 to GND-P) is installed for global ON/OFF control; use proper grounding to meet safety standards

2 Remote sense: Use twisted-pair cables for +S/-S pins to minimize electromagnetic interference

3 Programming: Follow the specified voltage ranges for PV (3~6V for 5V module, etc.) and PC (1.8~6V) pins to avoid damage

4 Parallel operation: Connect CS pins of all modules; ensure output voltage difference between modules <0.2V; total power must not exceed 1200W; use short, thick wires for parallel connections; remote control must turn all modules on/off simultaneously; do not use PC function in parallel mode

5 Derating: Follow derating curves—e.g., when output voltage <12V and ambient temp is -15~-30°C, derate output current to 90% of rated value; reduce load at high ambient temperatures as per the curve

6 Safety: Do not touch live parts when the power supply is operating; disconnect input power before maintenance; comply with all local electrical safety regulations

7 Overtemperature: If T-Alarm signal is high (4.5~5.5V), check cooling conditions (airflow, ambient temp) to prevent system shutdown
