Xingxiu DHP400L-4.2 LED power supply converts 180-264V AC to a 4.2V adjustable 3.8-4.2V rail at 80A rated (336W). PF>0.95, ≥88% efficiency, ripple 300 mVp-p, complete protections, compact size for LED display cabinets.
Xingxiu DHP400L-4.2 LED Display Switching Power Supply Description
Xingxiu DHP400L-4.2 is an AC-DC SMPS for LED display cabinets that converts 180-264V AC (nominal 200-240V) to a stable 4.2V rail. It delivers 80A-rated output (88A peak), typical efficiency ≥88% with PF >0.95 at full load, and includes OCP/SCP/OVP/OTP protections for reliable operation in demanding environments.
Product Features:
• Universal AC input 180-264V, 47-63Hz; nominal 200-240V
• Adjustable output 3.8-4.2V; 80A rated, 88A peak; 336W rated power
• High PF >0.95 @ 230V full load; efficiency ≥88% @ 230V
• Ripple and noise 300 mVp-p (20MHz, with 0.1uF + 10uF at output)
• Inrush current 60A @ 230V (cold); leakage current ≤1 mA @ 230V input
• Protections: over-current (auto recovery, ≥88A), short-circuit (auto recovery), open-loop OVP ≤6.8V, over-temperature (auto recovery)
• Isolation: insulation resistance DC500V 10 MΩ min (I/O, I-FG, O-FG); dielectric strength I/O 3000Vac 1 min ≤10 mA; I-FG 1500Vac 1 min ≤10 mA; O-FG 500Vdc 1 min ≤10 mA
• EMC: EN55022 Class A conducted/radiated; EMS per IEC 61000 level 3; voltage dips per IEC 61000-4-11
• Environment: −40°C to +70°C operating (derate at high temp); −40°C to +85°C storage; 10–90% RH operating; altitude −60 to 5000 m
• Construction: 180 x 68 x 26 mm; approx 350 g; natural convection cooling
• Terminals: 3-pin barrier input (E/L/N); 4-pin M4 output (V-, V-, V+, V+)
• Supports N+1 redundancy and current sharing
