产品特点 FEATURES

Modular power supply system (model NMP1K2-##EHHC-00 from MW/Meanwell) with 6 slots, supporting up to 1200W total output power.

1 Compatible with single-output (NMS-240, up to240W per module:5V/36A,12V/20A,24V/10A,48V/5A) and dual-output (NMD-240, up to240W combined) modules.

2 Wide input voltage range: AC90~264V or DC120~370V; frequency range47~63Hz; high power factor (PF>0.95@230VAC full load, PF>0.98@115VAC full load).

3 High efficiency: Up to91% (typical) at full load with 24V/48V modules; low ripple and noise (max100~250mVp-p depending on module).

4 Comprehensive safety compliance: Meets medical (2x MOPP between primary-secondary) and ITE standards (UL62368-1, EN60601-1 Ed3.1, IEC62368-1, etc.).

5 Rich protection functions: Overload (constant current limiting), overvoltage (shutdown, re-power to recover), overtemperature (shutdown, auto-recover when cool).

6 Flexible control capabilities: Global/local ON/OFF control; remote sense (compensates up to0.5V line drop); output voltage (PV) and current (PC) programming; DC OK signal (TTL level for output status); temperature alarm (T-Alarm); current sharing for parallel modules.

7 Compact mechanical design: Size250x127x41mm (NMP1K2), easy to mount with specified screws and torque.

使用场景 APPLICATIONS

Industrial automation: Powering PLCs, sensors, actuators, and control panels with flexible modular configuration.

1 Medical equipment: Suitable for diagnostic devices, patient monitors, and lab instruments that require medical safety compliance (2x MOPP).

2 Telecom and data communication: Providing stable power for routers, switches, base stations, and data center equipment.

3 Test and measurement: Adjustable output voltage/current for lab testing, prototype development, and electronic device validation.

4 Broadcast and media: Reliable power supply for audio/video mixers, cameras, and transmission gear.

5 Industrial IoT systems: Powering edge computing devices, wireless gateways, and IoT sensors in harsh environments.

注意事项 PRECAUTIONS

Installation: Ensure the shorting connector (RC1 to GND-P) is installed if global ON/OFF control is not used; otherwise, the system will have no output.

1 Mounting: Use M4 screws for front-end mounting with torque7~10 Kgf-cm; AC terminal torque≤12 Kgf-cm; DC terminal torque≤10 Kgf-cm; avoid over-tightening.

2 Temperature derating: When output voltage<12V and ambient temperature is -15°C~-30°C, derate output current to90% of rated; refer to derating curves for high ambient temperatures (>50°C).

3 Parallel operation: Connect CS pins of modules for current sharing; ensure output voltage difference between parallel modules<0.2V; max6 modules in parallel (NMP1K2); total power≤1200W; use short/large diameter wiring; remote control must turn all parallel modules ON/OFF simultaneously; do not use PC function in parallel.

4 Remote sense: Use twisted-pair cables for sense lines to reduce noise; compensate up to0.5V line drop.

5 ON/OFF control: Global control (RC1: short=ON, open=OFF) vs local control (RC2/RC3: open=ON, short=OFF) — note the logic difference to avoid errors.

6 Safety: Disconnect power before maintenance; ensure proper grounding; do not touch live parts when powered on; do not exceed rated specs.

7 Signal handling: DC OK and T-Alarm are TTL-level signals; do not exceed maximum sourcing current (10mA).
