产品特点 FEATURES

1 Modular design: NMP1K2 supports up to 6 slots, compatible with single-output (NMS-240) and dual-output (NMD-240) modules, allowing flexible configuration of multiple voltage outputs (5V/36A,12V/20A,24V/10A,48V/5A, dual 30V/5A etc.)

2 High power capacity: Max 1200W total output power, each module up to 240W.

3 Wide input range: 90~264VAC or 120~370VDC,47~63Hz, suitable for global use.

4 Safety compliance: Meets medical (2x MOPP between primary and secondary) and ITE standards, ensuring safe operation in medical and industrial environments.

5 Rich protection functions: Overvoltage protection (OVP), overcurrent protection (OCP), overtemperature protection (OTP), overload protection (OLP) for reliable operation.

6 Flexible control options: Global or local ON/OFF control, remote sense (compensates voltage drop up to 0.5V), output voltage/current programming (PV/PC functions for NMS-240), DC OK signal (TTL level for output status monitoring), T-Alarm for over-temperature warning.

7 Parallel operation support: Current sharing function allows parallel connection of modules (max 6 slots for NMP1K2) to increase output current, with balance between units.

8 Auxiliary power:5V/2A auxiliary output for NMP1K2, and5V/10mA for modules, supporting external control circuits.

使用场景 APPLICATIONS

1 Medical equipment: Suitable for medical devices requiring multiple voltage outputs and strict safety standards (2x MOPP compliance).

2 Industrial automation systems: Provides flexible power for PLCs, sensors, actuators, and control panels with diverse voltage needs.

3 Test and measurement instruments: Offers stable, configurable power for lab equipment, electronic testing devices.

4 Telecom and data communication systems: Supports multiple voltage levels for routers, switches, base stations, and communication modules.

5 Industrial control systems: Reliable power supply for DCS, SCADA systems, and industrial computers.

6 Customized power solutions: Ideal for applications needing multiple, adjustable DC voltage outputs in a compact form factor.

注意事项 PRECAUTIONS

1 Ensure the shorting connector accessory is properly assembled (RC1 to GND-P) for the power supply to output normally.

2 Derating guidelines:

3 When output voltage is below12V and ambient temperature is between -15℃ and -30℃, reduce output current to90% of rated value.

4 Follow derating curves for temperature and input voltage to avoid overheating or damage.

5 Remote sense: Use twisted pairs for +S/-S lines to minimize noise, and ensure correct connection to compensate for wiring voltage drop.

6 Parallel operation:

7 Connect CS pins of modules to enable current sharing; ensure output voltage difference between modules ≤0.2V.

8 Max parallel slots:6 for NMP1K2,4 for NMP650; total power must not exceed 1200W (NMP1K2) or650W (NMP650).

9 Do not use PC (output current programming) function when modules are in parallel.

10 Use short, thick wires for parallel connections to ensure current balance.

11 Local ON/OFF control: For NMS-240, open RC2 to GND for ON, short for OFF; for NMD-240, open RC2/RC3 to respective GNDs for ON.

12 DC OK signal: Monitor TTL signal (4.5~5.5V for ON,0~0.5V for OFF) to check module output status.

13 Overtemperature alarm: T-Alarm signal (high when over limit) indicates internal temperature issues; take cooling measures promptly.
