产品特点 FEATURES

Modular design: 1200W maximum power, supports up to 6 output modules (NMS-240 single output or NMD-240 dual output)

Wide input range: AC 90-264V, DC120-370VDC; frequency range 47-63Hz

High efficiency: Up to 91% (for H/K modules at 24V/48V nominal voltage)

Multiple output options: Single output modules (5V/36A,12V/20A,24V/10A,48V/5A) with adjustable voltage ranges; dual output modules (30V/5A each, combined 240W max)

Compliance: Meets medical (2x MOPP) and ITE safety standards (ANSI/AAMI ES60601-1, UL62368-1, etc.)

Protection features: Overload (constant current limiting or shut down), overvoltage (shut down), overtemperature (automatic recovery after cooling)

Flexible control: Global (RC1 to GND-P) and local (module-specific RC2/RC3) ON/OFF control; remote sense (compensates up to 0.5V drop)

Programming capabilities: Output voltage (PV) and current (PC) programming via external signals

Monitoring signals: DC OK (TTL level for module output status), T-Alarm (overtemperature alert)

Current sharing: Supports parallel operation of modules for higher current, with CS pins for balance

使用场景 APPLICATIONS

Medical equipment: Diagnostic devices, patient monitors, laboratory instruments (compliant with medical safety standards)

Industrial automation: PLC systems, motor drives, control panels requiring multiple power outputs

Test and measurement: Electronic test equipment, bench power supplies needing adjustable voltages

Communication systems: Routers, switches, base stations requiring stable and flexible power

Data centers: Server racks, storage systems needing modular power configurations

Other applications: Any system requiring multiple, adjustable DC power outputs with high reliability

注意事项 PRECAUTIONS

Derating: For output voltage <12V and ambient temp -15~-30°C, derate to 90% of rated current; refer to derating curves for ambient temp and input voltage

Global ON/OFF: Ensure the shorting connector (RC1 to GND-P) is installed; without it, no output is available

Local ON/OFF: For NMS-240 modules: open RC2 to GND for ON, short for OFF; for NMD-240: open RC2 (V1) or RC3 (V2) to respective GND for ON

Remote sense: Use twisted pairs for sense lines (+S/-S) to minimize noise; compensates up to 0.5V wiring drop

Current sharing: When paralleling modules: connect CS pins, ensure output voltage difference <0.2V, total power ≤1200W; max 6 modules in parallel; remote control must turn all modules on/off simultaneously; do not use PC function in parallel

Over temperature: T-Alarm signal (high level) indicates over temp; output shuts down and recovers after cooling

Wiring: Follow terminal pin assignments correctly; use recommended screw sizes (M4 for mounting, M3.5 for output terminals) and torque (7-10 Kgf-cm for mounting,10 Kgf-cm for output)

Safety: Operate within specified temperature (-30~+70°C) and humidity (20~90% RH non-condensing) ranges; avoid exposure to dust, moisture, or corrosive environments
