产品特点 FEATURES

Modular power supply with 1200W maximum total output power and 6 slots for output modules

Compatible with NMS-240 (single output) and NMD-240 (dual output) modules, each up to 240W

Wide input voltage range:90~264VAC or120~370VDC; frequency range:47~63Hz

High power factor:PF>0.95@230VAC full load, PF>0.98@115VAC full load

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

Multiple protection functions: Overload (constant current limiting), overvoltage (shut down, re-power to recover), overtemperature (shut down, auto-recover when cool)

Supports remote control features: Local ON/OFF for each module, global ON/OFF for the entire unit

DC OK signal (TTL level) to indicate output status; T-Alarm signal for overtemperature alert

Current sharing function for parallel operation of modules to ensure load balance

Remote sense function to compensate voltage drop on load wiring up to0.5V

Adjustable output voltage and current via programming pins (PV for voltage, PC for current)

High efficiency (up to91% typ. at full load with H/K modules at 24V/48V)

Auxiliary power output:5V/2A (for NMP1K2) to power control circuits or accessories

使用场景 APPLICATIONS

Industrial automation systems requiring multiple stable DC power outputs

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

Test and measurement instruments needing flexible voltage/current configurations

Telecommunication and data communication systems for powering various components

Data center equipment where modular and scalable power solutions are needed

Industrial control systems (PLCs, DCS) and factory automation setups

Laboratory research setups requiring adjustable and reliable power supplies

Telecom base stations and network infrastructure with multiple power needs

注意事项 PRECAUTIONS

Installation: Ensure the shorting connector (RC1 to GND-P) is assembled for global ON/OFF control; use recommended screw sizes (M4 for mounting, M3.5 for DC terminals) and torque (12Kgf-cm for AC terminal,10Kgf-cm for DC terminals)

Temperature derating: When output voltage is below12V and ambient temp is between -15°C to -30°C, derate output current to90% of rated value; follow derating curves for different ambient temps and input voltages

Parallel operation: Connect CS pins of modules to balance current; ensure output voltage difference between parallel modules is <0.2V; total output power should not exceed1200W; max6 modules in parallel for NMP1K2

Remote sense: Twist +S and -S lines to reduce interference; compensate voltage drop up to0.5V

Operation: Disconnect AC/DC input power before performing maintenance or module replacement; avoid exceeding max load for each module or total system; keep ambient temperature within -30~+70°C (with appropriate derating)

Safety: Follow ESD protection measures when handling modules; do not touch live parts during operation; ensure proper grounding to reduce leakage current (earth leakage <400uA@264VAC)

Auxiliary power: Do not exceed max load current (2A for NMP1K2) for +5V-AUX-P output
