MEAN WELL RSP-100-5 100W 1U metalen behuizing voeding

In a crowded server rack or industrial control cabinet, every millimetre of vertical space counts. The MEAN WELL RSP-100-5 delivers a full 100 watts of clean 5V DC power from a slim 1U-high metal enclosure that slips into tight spaces where conventional power supplies simply won't fit. With active PFC, a wide 85–264 VAC input, and comprehensive protection circuits, it is built for continuous duty in automation, signage, and communication systems.

Key specifications

• Output: 5V DC, 20A, 100W with ±10% voltage adjustment (4.5–5.5V)
• Input: 85–264 VAC or 120–370 VDC, 47–63 Hz, active PFC (>0.95 at 230VAC)
• Efficiency: up to 88%, low ripple & noise (100mVp-p max.)
• Protection: overload (105–135%, hiccup), overvoltage (5.75–6.75V, shutdown), short circuit (hiccup), all auto-recovery
• Cooling: free air convection, no fan required, operating temperature -30°C to +70°C
• Safety: UL60950-1, TUV EN60950-1, 3kVAC isolation, leakage current <1mA at 240VAC
• Reliability: MTBF 300,000 hours minimum, metal 1U low-profile enclosure

Why choose it

The RSP-100-5 combines high power density with rugged metal construction and a fanless design, eliminating noise and dust ingress while ensuring long-term stability. Its active PFC reduces harmonic distortion and improves energy efficiency across the full input range, making it suitable for worldwide use without switches or adjustments.

Ideal use cases

• Industrial automation and PLC systems requiring reliable 5V logic power
• LED signage and display panels in space-constrained installations
• Telecommunications and networking equipment in 19-inch racks
• Test and measurement instruments needing low-noise DC supply

Good to know

The unit is fully enclosed and convection cooled, so it can be mounted in any orientation without derating up to 50°C ambient. Output voltage can be trimmed via the built-in potentiometer to compensate for cable losses. Always ensure adequate ventilation around the unit to maintain optimal performance and lifespan.
