产品特点 FEATURES

1 Modular design: NMP1K2 model with 6 slots, supporting up to 1200W total power; compatible with NMS-240 single output modules (5V/36A,12V/20A,24V/10A,48V/5A) and NMD-240 dual output modules (30V@5A each, 240W max per module)

2 Safety compliance: Meets medical safety standards (2x MOPP isolation between primary and secondary circuits) and ITE standards (UL62368-1, EN60601-1 Ed3.1, TUV EN60601-1, etc.)

3 Versatile control functions: Global ON/OFF via RC1 pin (CN32-PIN6), local ON/OFF via RC2 pin (CN81-PIN3) for individual modules; remote sense (±S pins) compensates up to 0.5V voltage drop on load wiring; output voltage programming (PV pin) and current programming (PC pin) for flexible adjustments; DC OK TTL signal (4.5-5.5V when on, 0-0.5V when off) indicates output status; current sharing (CS pin) enables balanced parallel operation of modules

4 Comprehensive protection: Overload protection (constant current limiting), overvoltage protection (shut down output, recover by re-powering), over-temperature protection (auto shut down, recover when temperature drops); earth leakage current <400uA/264VAC

5 Efficient input/output: Wide input range (90-264VAC/120-370VDC), power factor >0.95@230VAC full load; high efficiency up to 91% (with H/K modules at nominal 24V/48V)

6 Compact mechanical design: Dimensions 250×127×41mm (L×W×H); recommended mounting with M4 screws (torque 7-10 Kgf-cm)

使用场景 APPLICATIONS

1 Industrial automation systems: Powering PLCs, sensors, actuators, and control panels in manufacturing and assembly lines

2 Medical equipment: Suitable for medical devices requiring 2x MOPP isolation (e.g., patient monitors, diagnostic instruments, lab analyzers)

3 Test and measurement setups: Providing stable, adjustable power for electronic component testing, lab instruments, and prototype development

4 Telecommunication networks: Supporting routers, switches, and small-scale telecom equipment with modular power needs

5 Data center and server applications: Powering server racks, storage devices, and network infrastructure components

6 Custom electronic systems: Flexible voltage/current configurations for specialized devices (mixing 5V,12V,24V,48V outputs via modular slots)

注意事项 PRECAUTIONS

1 Installation: Ensure proper grounding (FG terminal connection); use recommended screw sizes (M4 for front-end, M3.5 for output terminals) and torque values to avoid loose connections; keep unused slots covered with BLANK-NMS240 blank modules to maintain cooling efficiency and prevent dust accumulation

2 Cooling and derating: Maintain specified air flow direction for heat dissipation; refer to derating curves for output current adjustments under high ambient temperatures (e.g., 90% rated current when output voltage <12V and ambient temperature is between -15°C and -30°C; derate output at temperatures above 50°C)

3 Operation: Install the shorting connector (RC1 to GND-P) if not using external global ON/OFF control; when parallelizing modules, connect CS pins together and ensure output voltage difference between modules is less than 0.2V; do not exceed total rated power (1200W for NMP1K2)

4 Safety precautions: Disconnect input power before maintenance or module replacement; avoid touching live terminals when the unit is powered on; do not operate the unit beyond its specified input/output ranges

5 Programming: Follow the recommended external voltage ranges for PV (output voltage programming) and PC (output current programming) pins as per the product manual; ensure proper wiring for remote sense and control functions to avoid signal interference
