产品特点 FEATURES

1 Modular design with 6 slots, supporting up to 1200W total output power

2 Wide input voltage range: 90~264VAC / 120~370VDC, compatible with global power grids

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

4 Complies with multiple safety standards: IEC 60601-1 (medical, 2x MOPP isolation), IEC 62368-1 (ITE)

5 Rich protection functions: Over-temperature (auto-recovery after cooling), over-voltage (shut down, re-power to recover), over-load (constant current limiting)

6 Supports remote monitoring and control: DC OK signal (TTL level for output status), T-Alarm signal (over-temperature alert), remote ON/OFF (global/local control)

7 Current sharing function for parallel operation of NMS-240 modules, ensuring balanced load distribution

8 Auxiliary power outputs: 5V/2A (main unit) and 5V/10mA (per module) for external control circuits

9 Remote sense function to compensate for voltage drop on load wiring (up to 0.5V)

10 Output voltage/current programming options (PV/PC pins) for flexible adjustment (not for parallel modules)

使用场景 APPLICATIONS

1 Medical equipment: Suitable for devices requiring medical safety compliance (e.g., diagnostic instruments, patient monitors)

2 Industrial automation: Power supply for PLCs, DCS systems, sensors, and actuators in factory settings

3 Test and measurement: Stable power for lab instruments, oscilloscopes, signal generators

4 Communication systems: Backup or main power for routers, switches, base stations

5 Data centers: Modular power for server racks, storage systems needing multiple output voltages

6 LED lighting: High-power LED arrays requiring precise voltage/current control

7 Industrial control panels: Power for HMI, relays, and other control components

注意事项 PRECAUTIONS

1 Installation: Follow mechanical specifications (mounting torque ≤12Kgf-cm for main unit, ≤10Kgf-cm for modules), ensure sufficient ventilation for heat dissipation

2 Module compatibility: Use only NMS-240 (single output) or NMD-240 (dual output) modules; blank slots must be filled with BLANK-NMS240 accessory

3 Derating: Reduce output current to 90% of rated value when output voltage <12V and ambient temp is between -15℃ and -30℃; follow derating curves for high ambient temperatures

4 Power limit: Do not exceed total output power of 1200W (sum of all module powers)

5 Parallel operation: For NMS-240 modules, connect CS pins and GND mutually; ensure output voltage difference between modules <0.2V; do not use PC function in parallel mode; maximum 6 modules in parallel

6 Remote sense: Use twisted pairs for +S/-S lines to minimize interference

7 Auxiliary power: Do not exceed current limits (5V/2A for main unit auxiliary, 5V/10mA per module auxiliary)

8 Control logic: Ensure the shorting connector (RC1 to GND-P) is installed for global ON; follow local ON/OFF rules (open for ON, short for OFF for module RC2/RC3 pins)

9 Over-temperature alert: When T-Alarm signal is high (4.5~5.5V), check ventilation and load to prevent damage
