产品特点 FEATURES

1 Modular design: 1200W maximum power capacity with 6 slots for output modules (supports single/dual output modules up to 240W each, available voltages including 5V,12V,24V,48V)

2 Wide input range: AC 90~264V, DC120~370VDC, compatible with global power grids

3 High efficiency: Up to 91% efficiency at full load (with H/K modules at nominal 24V/48V)

4 Strong safety compliance: Complies with ANSI/AAMI ES60601-1 (medical standard, 2x MOPP isolation), UL62368-1, IEC60601-1, IEC62368-1 and other safety standards

5 Comprehensive protection: Overload (constant current limiting), overvoltage (shutdown and recover on repower), overtemperature (shutdown and auto-recover after cooling)

6 Flexible control functions: Supports global/local ON/OFF control, remote sense (compensates up to 0.5V voltage drop), output voltage/current programming, and DC OK signal (TTL level)

7 Current sharing capability: Allows parallel operation of multiple NMS-240 modules (max 6 slots for NMP1K2) to meet higher current demands

8 Auxiliary power supply: Provides 5V/2A auxiliary output for control circuits and 5V/10mA auxiliary power per module

9 Wide operating temperature range: -30~+70°C (with derating required at high temperatures)

使用场景 APPLICATIONS

1 Industrial automation: Power supply for PLCs, sensors, actuators and industrial control panels

2 Medical equipment: Suitable for medical devices requiring 2x MOPP isolation (e.g., diagnostic instruments, patient monitoring systems)

3 Telecom and data centers: Modular power solution for network switches, routers and server racks

4 Test and measurement: Stable power for laboratory equipment and electronic testing devices

5 Industrial control systems: Power for CNC machines, robotic systems and factory automation lines

6 Telecom infrastructure: Backup power modules for communication base stations

7 Data acquisition systems: Reliable power for data loggers and measurement sensors

注意事项 PRECAUTIONS

1 Derating requirement: Reduce output power according to the derating curve when ambient temperature exceeds 50°C; for output voltages below 12V and temperatures between -15~-30°C, derate output current to 90% of rated value

2 Installation: Follow recommended mounting torque (7~10 Kgf-cm for M4 screws), use proper screw sizes and penetration depth to avoid device damage

3 Remote control setup: Assemble the shorting connector (RC1 to GND-P) if global ON/OFF control is not used; correctly connect RC2/RC3 pins to GND for local control

4 Parallel connection rules: When connecting modules in parallel, link CS pins of all modules; ensure output voltage difference between modules is <0.2V; total power should not exceed 1200W; use short, large-diameter wires for parallel wiring

5 Sense lines: Twist +S/-S sense lines to minimize interference when using remote sense function

6 Auxiliary power: Do not exceed maximum load current of auxiliary outputs (2A for NMP1K2's +5V-Aux_P,10mA for module Vcc2)

7 Overtemperature handling: Monitor T-Alarm signal (TTL level) to address overheating issues promptly

8 Protection recovery: For overvoltage/overtemperature protection, repower the device after resolving the fault condition to recover output
