产品特点 FEATURES

1 Modular power supply design: NMP1K2 model has 6 slots, supporting up to 1200W total output power.

2 Multiple output module options: Compatible with single-output (NMS-240) and dual-output (NMD-240) modules; single-output modules offer adjustable voltages (5V/36A,12V/20A,24V/10A,48V/5A) with 240W max per module, dual-output modules support 30V/5A per channel (240W combined).

3 Wide input voltage range: 90~264VAC or 120~370VDC, adapting to various power grid conditions.

4 High safety compliance: Meets medical (2x MOPP between primary and secondary) and ITE standards (ANSI/AAMI ES60601-1 Ed.3.1, UL62368-1, TUV EN60601-1 Ed.3.1, etc.).

5 Comprehensive protection functions: Overload (O.L.P), overvoltage (O.V.P), overtemperature (O.T.P) protection; overload protection uses constant current limiting, O.V.P/O.T.P use shut-down and re-power recovery.

6 Flexible control options: Global ON/OFF control (via RC1 pin) and local ON/OFF control (via RC2/RC3 pins for modules); open state = ON, short state = OFF.

7 Remote sense capability: Compensates voltage drop on load wiring up to 0.5V via +S/-S pins.

8 Programming features: Supports output voltage programming (PV pin) and current programming (PC pin) for customized output.

9 Status monitoring signals: DC OK signal (TTL level, indicates module output status) and T-Alarm signal (overtemperature alarm).

10 Current sharing function: Allows parallel operation of modules (CS pins connected) to balance output current, suitable for high-power applications.

11 High efficiency: Up to 91% typical efficiency at full load with H/K modules (24V/48V) at nominal voltage.

使用场景 APPLICATIONS

1 Medical equipment: Suitable for devices requiring medical safety compliance (2x MOPP) like patient monitors, diagnostic instruments, and medical imaging systems.

2 Industrial automation: Ideal for PLCs, DCS systems, and industrial control panels due to modular design, wide input range, and robust protection.

3 Test and measurement instruments: Meets the precise voltage/current requirements of lab equipment, signal generators, and oscilloscopes via programmable features.

4 Communication systems: Supports base stations, routers, and switches with stable modular power supply and current sharing for high reliability.

5 Data centers: Provides scalable power solutions for server racks and storage systems, leveraging modularity to adjust power capacity as needed.

6 Renewable energy systems: Adapts to variable DC input from solar panels or wind turbines (120~370VDC range) for power conversion.

注意事项 PRECAUTIONS

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

2 Derating considerations: When output voltage is below 12V and ambient temperature is between -15°C and -30°C, reduce output current to 90% of rated value.

3 Parallel operation guidelines: For module parallelism, connect CS pins and GND pins of all modules; ensure voltage difference between modules is <0.2V; total output power should not exceed 1200W for NMP1K2; use short, large-diameter wiring for parallel connections.

4 Remote sense wiring: Use twisted pairs for +S/-S lines to minimize interference.

5 Mounting torque limits: Follow specified torque values (12Kgf-cm for AC input terminals, 10Kgf-cm for DC output terminals) to avoid damage.

6 Auxiliary power limits: Do not exceed the max current of auxiliary power outputs (+5V-AUX-P:2A for NMP1K2; Vcc2:10mA per module).

7 Local ON/OFF control: For dual-output modules (NMD-240), use RC2/RC3 pins to control each channel separately; ensure correct pin connections to avoid unintended ON/OFF states.
