产品特点 FEATURES

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

Wide input voltage range:90~264VAC or120~370VDC, suitable for global applications.

High power factor:PF>0.95 at230VAC full load, PF>0.98 at115VAC full load, reducing grid interference.

High efficiency:Up to91% (full load with H/K modules at nominal24V/48V).

Modular output options:Supports single output modules (5V/36A,12V/20A,24V/10A,48V/5A) and dual output modules (each up to30V/5A), with adjustable voltage ranges for flexibility.

Multiple protection functions:Overload protection (constant current limiting or hiccup mode), overvoltage protection (shut down and recover on re-power), overtemperature protection (automatic recovery after cooling).

Remote control capabilities:Global or local ON/OFF control via dry contact or electrical signal; remote sense function to compensate for wiring voltage drop (up to0.5V).

Current sharing function:Allows parallel operation of modules for higher current output, with CS pins ensuring balanced current distribution.

Auxiliary power outputs:5V/2A (front-end) and5V/10mA (per module) for control circuits.

DC OK signal:TTL level signal indicating module output status (4.5~5.5V when ON,0~0.5V when OFF).

Compliance with safety standards:IEC60601-1 (medical), UL62368-1, EN60601-1, ensuring reliability in critical applications.

Compact design:Suitable for rack-mounted or embedded installations in industrial and medical equipment.

注意事项 PRECAUTIONS

Before powering on, verify that the input voltage matches the product's specified range (90~264VAC or120~370VDC).

Ensure proper grounding of the device to prevent electrical shocks and reduce electromagnetic interference.

Do not exceed the maximum total output power (1200W for NMP1K2) or individual module ratings to avoid damage.

When using remote sense, use twisted-pair wiring and keep the length short to minimize noise and voltage drop.

For parallel operation of modules:Connect CS pins of all modules, ensure output voltage differences are <0.2V, and do not exceed the maximum number of parallel modules (6 for NMP1K2).

Follow derating guidelines for high ambient temperatures:Refer to the derating curve to reduce output current in high-temperature environments (e.g., output current derated to90% when ambient temp is-15~-30℃ for output voltages <12V).

Maintain adequate ventilation around the device to prevent overheating; avoid blocking air vents.

Do not operate the device in environments with dust, moisture, or corrosive gases, as this may lead to component failure.

Disconnect the power supply before replacing modules or performing maintenance to avoid electrical hazards.

Use only compatible modules (NMS-240 or NMD-240 series) from the manufacturer to ensure performance and safety.
