1 Modular power supply with 6 slots (NMP1K2 model) supporting up to 1200W total output power

2 Compatible with NMS-240 (single output:5V/36A,12V/20A,24V/10A,48V/5A) and NMD-240 (dual output) modules

3 Global (RC1 pin) or local (module RC2/RC3 pins) ON/OFF control functionality

4 Remote sense function (+S/-S pins) to compensate voltage drop on load wiring (up to 0.5V)

5 Output voltage (PV pin) and current (PC pin) programming for NMS-240 modules

6 DC OK signal (TTL level) to indicate module output status

7 Over-temperature alarm (T-Alarm signal, TTL level) for internal temperature monitoring

8 Current sharing (CS pin) support for parallel operation of NMS-240 modules (max 6 slots)

9 Auxiliary power outputs: +5V-AUX_P (2A for NMP1K2) and Vcc2 (5V/10mA for modules)

10 Wide input voltage range:90-264VAC or 120-370VDC

11 High efficiency (up to 91% at full load)

12 Multiple protection features: Overload (OLP), Overvoltage (OVP), Over-temperature (OTP), Short circuit (SCP)

13 Compliance with international safety standards (IEC 60601-1, UL62368-1, etc.)

1 Industrial automation systems requiring multiple DC voltage outputs

2 Medical equipment (compliant with medical safety standards)

3 Test and measurement instruments needing precise voltage/current adjustment

4 Telecommunication systems with parallel power redundancy requirements

5 Data centers/server racks using modular power solutions

6 Laboratory setups for R&D and prototyping

7 Embedded systems with multiple power rails

8 Industrial control panels with diverse power needs

1 Ensure the shorting connector (RC1 to GND-P) is installed if global ON/OFF is not used; otherwise, no output will be present

2 For remote sense, use twisted pairs for +S and -S lines to minimize noise

3 Follow spec sheet guidelines for external voltage ranges when programming voltage/current (PV/PC)

4 For parallel operation of NMS-240 modules:

a. Connect CS pins together and ensure output voltage difference <0.2V

b. Total output current ≤ (rated current per module × number of modules) and total power ≤1200W

c. Use short, large-diameter wires for parallel connections

d. Remote control should turn all parallel modules ON/OFF simultaneously

1 Over-temperature alarm (T-Alarm) indicates internal temp exceedance; implement cooling measures promptly

2 For local module control: Open RC2 (NMS) or RC2/RC3 (NMD) to turn ON, short to turn OFF

3 Refer to derating curves for high-temperature environments to adjust output current
