产品特点 FEATURES

1 Modular chassis design: NMP1K2 model with 6 slots, supporting up to1200W total power; compatible with NMS-240 (single output, max240W per module:5V/36A,12V/20A,24V/10A,48V/5A) and NMD-240 (dual output, max240W combined) modules.

2 Wide input compatibility: AC90-264V (47-63Hz) or DC120-370VDC, suitable for global industrial and medical applications.

3 High energy efficiency: Up to91% at full load (when using H/K modules at nominal24V/48V), reducing energy consumption and heat generation.

4 Comprehensive protection: Overload (constant current limiting or shut-down), overvoltage (shut-down, repower to recover), overtemperature (auto shut-down and recover when cooled), and short-circuit protection to ensure device safety.

5 Flexible control options: Global ON/OFF (via RC1 pin) or local ON/OFF (via RC2/RC3 pins for modules); remote sense function compensates up to0.5V wiring voltage drop; PV (voltage programming) and PC (current programming) pins for precise output adjustment; DC OK signal (TTL level:4.5-5.5V ON,0-0.5V OFF) indicates module status; T-Alarm signal (high when over temp) alerts to overtemperature.

6 Current sharing capability: Allows parallel connection of NMS-240 modules (max6 for NMP1K2) with mutual CS pin connection to balance load, ensuring stable power distribution.

7 Safety compliance: Meets ITE standards (UL62368-1, EN62368-1) and medical standards (ANSI/AAMI ES60601-1 Ed3.1,2x MOPP isolation between primary and secondary), suitable for medical and industrial environments.

8 Auxiliary power outputs: +5V-AUX_P (2A for NMP1K2) for external circuits; Vcc2 (5V/10mA per module) for module control functions.

使用场景 APPLICATIONS

1 Industrial automation: Powering PLCs, sensors, actuators, and control panels requiring multiple, adjustable voltage outputs.

2 Medical equipment: Supporting diagnostic tools, patient monitors, and lab instruments (due to medical safety compliance and isolation).

3 Telecommunications: Supplying power to network switches, routers, and communication devices where modularity and redundancy (parallel modules) are needed.

4 Test and measurement: Providing precise, programmable voltage/current outputs for testing electronic components or devices.

5 Data centers: Integrating into server racks or storage systems for efficient, modular power distribution.

6 Renewable energy systems: Compatible with DC input from solar/wind setups to power various loads.

注意事项 PRECAUTIONS

1 Installation: Ensure proper grounding via FG terminal; use recommended screw sizes (M4 for mounting, M3.5 for terminals) and torque (7-12Kgf-cm) to avoid loose connections or damage.

2 Module management: Fill blank slots with BLANK-NMS240 accessories; when using parallel modules, connect CS pins mutually and ensure output voltage difference between modules <0.2V.

3 Temperature derating: For ambient temp < -15°C and output voltage <12V, derate output current to90% of rated value; follow derating curves for different input voltages and ambient temps to prevent overheating.

4 Control setup: If not using global ON/OFF control, assemble the shorting connector (RC1 to GND-P) to enable output; for local control, use dry contacts (open=ON, short=OFF) between RC2/RC3 and GND pins.

5 Parallel operation: Do not exceed total power (1200W) or max modules (6); avoid PC function in parallel mode; use short, thick wires for parallel connections to minimize voltage drop.

6 Safety precautions: Operate in environments within specified limits (temp -30~+70°C,20-90% RH non-condensing); follow local electrical codes and safety standards to prevent electrical hazards.
