产品特点 FEATURES

1 Modular structure: 6-slot front-end (NMP1K2) supporting up to 6 NMS-240 (single output) or NMD-240 (dual output) modules, total power capacity up to 1200W

2 Diversified output options: Single output modules (5V/36A,12V/20A,24V/10A,48V/5A) with adjustable voltage ranges; dual output modules (each up to 30V/5A, combined 240W)

3 Strict safety compliance: Meets IEC60601-1 (medical), IEC62368-1 (ITE) standards, with 2x MOPP isolation between primary and secondary circuits

4 Comprehensive protection mechanisms: Overload (OLP), overvoltage (OVP), over-temperature (OTP), short circuit protection; OTP triggers automatic shutdown and recovers after cooling

5 Flexible control functions: Global/local ON/OFF control, remote sense (compensates up to 0.5V voltage drop), output voltage (PV) and current (PC) programming, DC OK signal (indicates output status), current sharing (CS) for parallel operation

6 High efficiency and reliability: Up to 91% efficiency (with H/K modules at 24V/48V), wide input voltage range (90-264VAC,120-370VDC), low ripple and noise (max 250mVp-p)

7 Auxiliary power supplies: 5V/2A front-end auxiliary output and 5V/10mA module auxiliary output for control circuit powering

8 Compact design: Front-end dimensions 250×127×41mm, easy to integrate into various systems

使用场景 APPLICATIONS

1 Industrial automation: Powering PLCs, sensors, actuators, and control systems requiring multiple stable DC voltage levels

2 Medical equipment: Suitable for devices complying with IEC60601-1 standards, such as diagnostic tools, patient monitors, and laboratory instruments

3 Test and measurement: Providing adjustable, precise DC power for electronic component testing, circuit board debugging, and lab experiments

4 Telecom and data communication: Supporting routers, switches, base stations, and server racks needing diverse voltage outputs

5 Broadcast and media: Powering audio/video equipment, studio systems, and transmission devices requiring reliable and clean power

6 Renewable energy systems: Integrating with solar or wind power setups to convert and distribute DC power to various loads

7 Embedded systems: Supplying power to custom embedded devices with multiple voltage requirements

注意事项 PRECAUTIONS

1 Installation precautions: Ensure proper grounding via FG terminal to prevent electric shock; use recommended screws (M4 for front-end, M3.5 for modules) with specified torque (7-10 Kgf-cm for front-end,10 Kgf-cm for modules)

2 Operating environment: Avoid high humidity (over90% RH non-condensing) or extreme temperatures (-30°C to +70°C); follow derating rules (e.g.,90% rated current for Vo<12V at -15°C to -30°C)

3 Parallel operation guidelines: Connect CS pins of modules together; ensure output voltage difference <0.2V between parallel modules; total power must not exceed1200W; use short, thick wires for parallel connections

4 Control function usage: For global ON/OFF, install the shorting connector (RC1 to GND-P); local ON/OFF uses RC2 (NMS) or RC2/RC3 (NMD) pins (open=ON, short=OFF)

5 Safety operations: Do not overload modules beyond rated power; disconnect input power before servicing or module replacement; avoid touching live terminals

6 Maintenance tips: Regularly check for loose connections and dust accumulation (clean with dry air); replace faulty modules promptly to prevent system failure

7 Derating compliance: Refer to derating curves for output current adjustments under high ambient temperatures or low input voltages
