产品特点 FEATURES

1 Modular power supply from MW (明纬), model NMP1K2-EHHHKH-03, part of NMP series with 6 slots supporting up to 1200W total output.

2 Supports multiple single-output modules (NMS-240) with adjustable voltages:24V@10A (code H),48V@5A (code K), etc., and dual-output modules (NMD-240) are available.

3 Complies with medical safety standards (2x MOPP between primary and secondary) and ITE standards (ANSI/AAMI ES60601-1, UL62368-1, TUV EN60601-1, EN62368-1, IEC60601-1, IEC62368-1).

4 Equipped with comprehensive protection: Overvoltage (OVP), overcurrent (OCP), overtemperature (OTP) protection; shutdown on fault, recoverable by re-powering.

5 Key functionalities: Remote sense (compensates up to0.5V wiring drop), global/local remote ON/OFF control, DC OK TTL signal (indicates module output status), current sharing for parallel operation, output voltage/current programming (via PV/PC pins).

6 High efficiency: Up to91% at full load with H/K modules (24V/48V nominal voltage).

7 Wide input range:90~264VAC or120~370VDC, frequency range47~63Hz; power factor >0.95@230VAC full load.

8 Low ripple & noise: Max150mVp-p for24V modules, max250mVp-p for48V modules.

9 Hold-up time: Typ.16ms@230VAC75% total output,10ms@230VAC full output.

使用场景 APPLICATIONS

1 Industrial automation: Powering PLCs, servo drives, sensors, and actuators requiring multiple stable DC voltages.

2 Medical equipment: Suitable for diagnostic devices, patient monitors, and lab instruments due to medical safety compliance.

3 Telecommunications: Supporting network switches, routers, and telecom infrastructure with diverse voltage needs.

4 Test & measurement: Providing adjustable, precise DC outputs for lab testing of prototypes or electronic components.

5 Data centers: Modular, scalable power solution for server racks or storage systems needing reliable power distribution.

6 Embedded systems: Custom electronic devices with multiple voltage rails (e.g.,24V for motors,48V for power stages).

注意事项 PRECAUTIONS

1 Installation: Ensure proper grounding; use M4 screws for mounting with torque7~10 Kgf-cm to prevent loose connections.

2 Temperature derating: Derate output current as per the curve when ambient temperature exceeds50°C; for output voltages <12V and temp between-15°C to-30°C, derate to90% of rated current.

3 Remote control: For global ON/OFF, connect RC1 (CN32-PIN6) to GND-P (CN32-PIN3); local module ON/OFF uses RC2 (pin3) and GND (pin1/2) (open=ON, short=OFF).

4 Parallel operation: Connect CS pins of all modules for current sharing; total output power must not exceed1200W; use short, thick wires to minimize voltage drop; max6 modules in parallel for NMP1K2.

5 Protection handling: If OVP/OCP/OTP triggers shutdown, re-power the unit to recover; overload protection uses constant current limiting.

6 Wiring guidelines: Use20~26AWG wires for control pins, appropriate gauge for power lines to ensure safety and performance.

7 Accessory requirement: The shorting connector (RC1 to GND-P) must be assembled if global ON/OFF is not used to enable output.
