产品特点 FEATURES

1 Modular design with 6 slots for flexible configuration (supports NMS-240 single output and NMD-240 dual output modules)

2 Wide input voltage range:90~264VAC /120~370VDC, frequency range:47~63Hz

3 High efficiency up to 91% (typical, full load with H/K module at nominal 24V/48V)

4 Compliance with safety standards: medical (2x MOPP between primary and secondary) and ITE standards (ANSI/AAMI ES60601-1, UL62368-1, etc.)

5 Multiple protection functions: overload (constant current limiting), overvoltage (shut down and re-power to recover), overtemperature (shut down and auto-recover after cooling)

6 Global and local ON/OFF control options: global via RC1 (CN32-PIN6) and GND-P; local via RC2 (for NMS) or RC2/RC3 (for NMD)

7 Auxiliary power outputs:+5V-AUX-P (2A max for NMP1K2), Vcc2 (5V/10mA for NMS modules)

8 Support for current sharing (CS pin connection) for parallel operation of NMS modules

9 DC OK signal (TTL level) to indicate output status of modules

10 T-Alarm signal (TTL level) for overtemperature warning

11 Remote sense function (±S pins) to compensate voltage drop on load wiring (up to 0.5V)

12 Output voltage (PV pin) and current (PC pin) programming options (for NMS modules)

13 Compact mechanical size:250*127*41mm (L*W*H), net weight around 2kg (typical)

使用场景 APPLICATIONS

1 Industrial automation systems requiring multiple stable DC power outputs

2 Medical equipment (compliant with medical safety standards) such as diagnostic devices, patient monitors

3 Test and measurement instruments that need configurable voltage/current outputs

4 Communication systems (routers, switches, base stations) needing reliable power supply

5 Industrial control panels and rack-mounted equipment

6 Equipment requiring parallel operation for higher power capacity (up to 6 NMS modules for NMP1K2)

7 Applications where remote monitoring (DC OK, T-Alarm) and control (ON/OFF, programming) are needed

8 Devices operating in wide temperature environments (-30~+70℃ with appropriate derating)

注意事项 PRECAUTIONS

1 Installation:Use M4 screws with recommended torque (7~10 Kgf-cm) for mounting; ensure proper air flow direction as per mechanical specification

2 Global ON/OFF:If not using the global control function, install the shorting connector (RC1 to GND-P) that comes with the unit

3 Remote sense:Use twisted pair wires for ±S pins to minimize interference; do not exceed 0.5V compensation limit

4 Derating guidelines:

5 When ambient temperature is between -15℃ and -30℃ and output voltage <12V, derate output current to 90% of rated value

6 Follow derating curves for different input voltages and ambient temperatures to avoid overheating

7 Parallel operation (for NMS modules):

8 Use same module type; ensure output voltage difference between modules <0.2V

9 Total output power should not exceed 1200W (NMP1K2 max)

10 Connect CS pins of all modules together; use short, large-diameter wires for parallel connections

11 Do NOT use the PC (current programming) function when modules are in parallel

12 Blank slots:Must install BLANK-NMS240 accessory in unused slots to maintain proper cooling and safety

13 Protection functions:In case of overvoltage/overtemperature protection, re-power the unit after resolving the issue to recover; overload protection uses constant current limiting

14 Safety:Operate within rated input/output ranges; avoid touching live parts during operation; follow all safety standards and guidelines provided in the specification
