## Long description

The MEAN WELL RSP-1000-48 is a 1U metallic power supply unit delivering 1008 W output at 48 V. It accepts an AC input of 90–264 V, 47–63 Hz and includes active PFC and active surge current limiting for stable mains behaviour. The unit is cooled by a high-quality ball-bearing fan, offers remote sense, remote ON-OFF control and a 12 V/0.1 A auxiliary remote control output. Safety approvals include UL60950-1 and TUV EN60950-1; MTBF is 313100 hours. Physical dimensions are 127 × 295 × 41 mm.
Advantages
The RSP-1000-48 provides high conversion efficiency up to 91% and built-in active PFC to improve power factor and reduce mains disturbances. Output voltage trimming of ±10% enables fine adjustment to match load requirements. Active surge current limiting protects the unit and connected equipment during AC inrush events. Remote sense and remote ON-OFF increase installation flexibility while the auxiliary 12 V/0.1 A output supports control circuits.
Suitable for
 Server racks and 1U industrial enclosures
 Telecommunications and network equipment
 Industrial control systems and automation
 Embedded systems requiring 48 VDC supply
