产品特点 FEATURES

1 Modular design: NMP1K2 model supports up to 6 slots with 1200W max total power; model NMP1K2-CEHCEH-00 is configured with 6 modules including NMS-240-05 (5V), NMS-240-12 (12V), NMS-240-24 (24V) each repeated twice

2 Wide input range: AC 90~264V, DC120~370VDC; frequency range 47~63Hz

3 High performance: Power factor >0.95 (230VAC full load), typical efficiency up to91% (full load with H/K modules at 24V/48V)

4 High isolation: Primary-Secondary (2x MOPP), Primary-Earth (1x MOPP); withstand voltage: I/P-O/P=4KVAC, I/P-FG=2KVAC, O/P-FG=0.5KVAC

5 Multiple protection functions: Over-temperature (auto-recover after cooling), over-voltage (shut down, re-power to recover), overload (constant current limiting or hiccup mode)

6 Flexible control options: Global/local ON/OFF control (open/short logic), remote sense (compensate up to0.5V wiring drop), output voltage/current programming (PV/PC pins), DC OK signal (TTL level for output status)

7 Parallel operation support: Current sharing (CS pin connection) for modules to balance load; up to6 modules in parallel with total power not exceeding1200W

8 Safety compliance: Meets medical and ITE standards (ANSI/AAMI ES60601-1 Ed3.1, UL62368-1, TUV EN60601-1 etc.)

9 EMC compliance: EN55032 Class B (emission), EN61000 series (immunity like ESD level4, surge level4)

10 Auxiliary power: Front-end provides5V/2A, modules provide5V/10mA for control circuits

11 Wide operating temperature: -30~+70℃ (with derating as per curve)

使用场景 APPLICATIONS

1 Industrial automation: Power supply for PLCs, DCS systems and modular control panels

2 Medical equipment: Compatible with devices requiring 2x MOPP isolation (e.g., diagnostic instruments, patient monitors)

3 Test & measurement: Flexible power for electronic testing setups needing adjustable voltages/currents

4 Telecommunications: Power for base stations, network equipment and modular communication systems

5 Data centers: Parallel operation for high-current needs in server racks or storage systems

6 Modular electronic systems: Applications needing customizable power configurations (different voltage/current outputs)

7 Remote monitoring systems: Use DC OK and T-Alarm signals for real-time power status tracking

注意事项 PRECAUTIONS

1 Installation: Use M4 screws (7-10 Kgf-cm torque) for front-end mounting; M3.5 screws (max10 Kgf-cm) for output terminals; ensure proper grounding

2 Wiring: For remote sense, use twisted pairs for +S/-S lines; for parallel operation, use short/large-diameter wires to minimize voltage drop

3 Control logic: Local ON/OFF (RC2/RC3 pins): open=ON, short=OFF; global ON/OFF (RC1 pin): short=ON, open=OFF (install shorting connector if not using global control)

4 Parallel operation: Connect CS pins of all modules; ensure output voltage difference <0.2V among modules; total load not exceed1200W; PC function disabled in parallel

5 Derating: For output voltage <12V and temp -15~-30℃, derate current to90% of rated; reduce load at higher ambient temps per derating curves

6 Safety: Do not operate in moist/dusty/corrosive environments; avoid touching live parts when powered on

7 Maintenance: Regularly check for overheating (monitor T-Alarm signal); inspect wiring connections for looseness; replace modules only with compatible MW NMS/NMD series

8 Connector compatibility: Use HRS DF11 series connectors for control pins to ensure reliable connections
