产品特点 FEATURES

1 Modular design: NMP series (650W/1200W front-end) with interchangeable output modules (NMS-240 single output, NMD-240 dual output) for flexible voltage/current configurations

2 Multiple control functions: Global/Local ON/OFF, Remote Sense (0.5V compensation), Output Voltage Programming (PV), Constant Current Programming (PC), Current Sharing (CS), DC OK signal (TTL level for output status), T-Alarm (over-temperature signal)

3 Comprehensive protection: Over Voltage (OVP), Over Current (OCP), Over Temperature (OTP), Over Load (OLP); OTP auto-recovers when temp drops, others require re-power to reset

4 Compliance: Meets safety standards (IEC 60601-1 Ed3.1 for medical, IEC 60950-1 for ITE), EMC standards (EN55032 for emission, EN61000 series for immunity)

5 Auxiliary power: 5V-Aux_P (2A for NMP1K2,1.5A for NMP650) and Vcc2 (5V/10mA for NMS-240) for control circuits

6 Mechanical flexibility: Standard mounting holes (M4), clear connector pin assignments (CN32 for front-end, CN81 for modules), specified torque limits (12Kgf-cm for AC terminals,10Kgf-cm for DC terminals)

使用场景 APPLICATIONS

1 Medical equipment: Diagnostic devices (ultrasound, blood analyzers), patient monitoring systems (ECG, EEG) due to medical safety compliance

2 Industrial automation: PLCs, motor drives, control panels requiring multiple stable power outputs

3 Telecommunications: Servers, routers, base stations needing reliable power with current sharing for redundancy

4 Test & measurement: Instruments (oscilloscopes, signal generators) requiring precise voltage/current control

5 LED lighting: High-power LED arrays needing flexible voltage and current programming

6 Any application needing scalable, configurable power with advanced control and protection features

注意事项 PRECAUTIONS

1 Global ON/OFF control: If not using, assemble the shorting connector (RC1 to GND-P) to enable output; otherwise, no power is supplied

2 Remote Sense: Use twisted pairs for sense lines (+S/-S) to minimize noise; compensates up to 0.5V voltage drop on load wires

3 Output Programming:

4 PV (voltage): Reference to GND; adjust range same as VR60 (e.g.,3-6V for5V module)

5 PC (current): Reference to GND; apply1.8-6V to get40-100% of rated current; do NOT use PC function when modules are paralleled

6 Local ON/OFF:

7 NMS-240: Keep RC2 open to GND for ON, short for OFF

8 NMD-240: Keep RC2 (V1)/RC3 (V2) open to respective GNDs for ON, short for OFF

9 Current Sharing:

10 Connect CS pins of all parallel modules together; ensure output voltage difference <0.2V between modules

11 Max parallel slots:4 for NMP650,6 for NMP1K2; total current ≤ sum of rated currents of modules

12 Use short, large-diameter wires for parallel connections; remote control must trigger all modules simultaneously

13 Temperature derating: For NMD-240, if output voltage <12V and ambient temp is -15 to -30°C, reduce current to90% of rated value

14 Mechanical installation:

15 Use recommended screw sizes (M4 for mounting, M3.5 for DC terminals) and torque limits to avoid damage

16 Wire strip length:10mm for DC terminals to ensure proper connection

17 Protection: If OVP/OCP/OLP is triggered, power cycle the unit to recover; OTP auto-recovers when internal temp drops below threshold
