产品特点 FEATURES

Modular Output Options: Supports NMS-240 (single output) modules with voltage/current combinations:5V@36A,12V@20A,24V@10A,48V@5A; NMD-240 (dual output) modules with each channel adjustable from3-30V (max240W per channel)

Flexible Power Capacity: NMP650 (4 slots, max650W) and NMP1K2 (6 slots, max1200W) to adapt to varying power demands

Precise Control Functions: Global ON/OFF (via RC1-GND-P) and local ON/OFF (per module via RC2/RC3-GND) for output management; remote sense (+S/-S) compensates voltage drop up to0.5V

Advanced Monitoring & Programming: Output voltage programming (PV pin), output current programming (PC pin); DC OK signal (TTL level:4.5-5.5V=on,0-0.5V=off) indicates module status; T-Alarm (TTL level: high=overtemp, low=normal) warns of overheating

Parallel Operation Support: Current sharing (CS pin connection) for parallel modules; max4 modules for NMP650,6 for NMP1K2; total power not exceeding unit's max (650W/1200W)

Auxiliary Power Supplies: +5V-AUX-P (2A for NMP1K2,1.5A for NMP650) and Vcc2 (5V/10mA for NMS modules) for external control circuits

Comprehensive Protections: Overload (constant current limiting or hiccup mode), overvoltage (shutdown and restart), overtemperature (shutdown and auto-recover after cooling)

Derating Compatibility: Adjusts output current based on ambient temp and voltage (e.g.,90% rated current for Vo<12V at -15~-30°C; refer to derating curves for temp/input voltage adjustments)

使用场景 APPLICATIONS

Industrial Automation Systems: Powering PLCs, sensors, actuators requiring multiple DC voltages

Test & Measurement Equipment: Providing adjustable and stable voltages for component testing (e.g., electronic part characterization)

Telecom & Data Centers: Redundant power via parallel operation to ensure uninterrupted service

Factory Automation Lines: Supporting devices with different voltage needs (motors, controllers, displays)

Laboratory Setups: Flexible power solutions for R&D projects needing customizable voltage/current outputs

Robotics Systems: Supplying power to subsystems (sensors, motors, control boards) with precise voltage control

注意事项 PRECAUTIONS

1 Global ON/OFF Setup: Ensure the shorting connector (RC1 to GND-P) is assembled when not using global control; without it, the unit has no output

2 Local ON/OFF Operation: For NMS-240 modules: open RC2-GND to turn on, short to turn off; for NMD-240: open RC2-GND1 (V1) or RC3-GND2 (V2) to turn on, short to turn off

3 Remote Sense Usage: Use twisted-pair wires for +S/-S pins to minimize interference; connect +S to load's positive terminal and -S to load's negative terminal

4 Parallel Operation Guidelines: Max modules:4 for NMP650,6 for NMP1K2; connect CS pins of all modules; ensure output voltage difference <0.2V; use short/large-diameter wires; total power ≤ unit's max (650W/1200W)

5 Derating Requirements: For Vo<12V and ambient temp -15~-30°C: derate current to90% of rated; refer to derating curves for temp/input voltage adjustments

6 Programming Functions: Follow specified voltage ranges for PV (output voltage) and PC (current) programming; reference signals to correct GND pins

7 Safety Precautions: Ensure proper grounding; do not exceed max ratings of modules/unit; avoid touching live parts when operational

8 Accessories: For non-standard parallel/series connections, contact the manufacturer for appropriate accessories
