SDR-120-48 48V 2.5A 120W Industrial Switching Power Supply with Wide Input Voltage for Telecom/Industrial Equipment

The SDR-120-48 switching power supply delivers 120W continuous power with 48VDC/2.5A output, engineered for industrial applications requiring high reliability. Its wide 88-264VAC input range (127-370VDC compatible) accommodates global voltage fluctuations, while 0.99 power factor (115VAC full load) optimizes energy consumption. The unit features multiple protection mechanisms: Overload protection activates at 110-150% power with auto-recovery, while overvoltage cutoff safeguards connected devices at 56-65V. Technical highlights include ±0.5% linear regulation, ±1% load regulation, and <120mVp-p low-noise output critical for precision instruments. With 94% typical efficiency (115VAC input), it reduces operational costs and thermal stress. The compact design (199*99*38mm) integrates industrial-grade components supporting -30°C to +70°C operation, 3000m altitude tolerance, and 10G vibration resistance. Certified to UL62368-1/EN61558/BSMI standards, it's ideal for telecom infrastructure, LED arrays, industrial control systems, and renewable energy installations. Includes 3-year warranty and built-in short-circuit/over-temperature protection with automatic recovery function.
