Megmeet MCP300WL Series LED Display Switching Power Supply

Megmeet MCP300WL Series LED Display Switching Power Supply Description

The Megmeet MCP300WL series (MCP300WL-3.8, MCP300WL-4.2, MCP300WL-4.5, MCP300WL-5.0) are 300W LED display power supplies engineered for stable, efficient, and reliable constant-voltage power to LED modules and displays. Each model delivers a regulated +5V DC output (model variants correspond to different nominal output tolerance/usage scenarios), supports universal AC input (90–264 VAC) with active PFC, and includes comprehensive protections (overcurrent, short-circuit, overvoltage, overtemperature). Designed for indoor and industrial LED display applications, the MCP300WL series meets safety and EMC standards and offers robust thermal, vibration, and shock resistance for field and factory use.

Product Features:
• All models listed: MCP300WL-3.8, MCP300WL-4.2, MCP300WL-4.5, MCP300WL-5.0.
• 300W normal output power per unit.
• Universal AC input: 90–264 VAC (normal 100–240 VAC), 47–63 Hz.
• Active PFC with power factor > 0.95 at full load (220 VAC).
• High efficiency: ≥ 87.5% at 220 VAC, full load.
• Low leakage current: < 3.5 mA @ 240 VAC.
• Fast inrush/hold-up characteristics: typical inrush ~60 A peak (cold start @230 VAC); hold-up time ≥ 10 ms at full load (100 VAC & 220 VAC).
• Output specification: +5V DC, regulation ±5%, rated current 60 A (peak current testing per spec).
• Low ripple & noise: ≤ 150 mV p-p @ 25 °C; ≤ 300 mV p-p @ −40 °C (20 MHz bandwidth measurement).
• Fast transient response: slew rate 1 A/µs; designed for 25%→50% and 50%→75% load steps.
• Protections: overcurrent protection (>65 A typical, auto-turnoff), short-circuit protection (auto-turnoff/recovery), overvoltage protection (+5V line ≤ 6.5V, auto-restart after power cycle), overtemperature protection (OTP >70 °C, self-recovery).
• Robust insulation & safety: input-to-output/input-to-FG/output-to-FG insulation resistance ≥ 10 MΩ (DC 500 V); dielectric strength per spec (input-output 3000 VAC, input-FG 1500 VAC, output-FG 500 V).
• Safety and EMC: UL60950 / IEC60950 / EN60950 / GB4943; EMI EN55032 Class B, FCC Part 15 Class B; EMS: ESD, EFT, Surge, DIP per IEC/GB standards.
• Wide environmental range: operating −40 °C to +60 °C; storage −40 °C to +85 °C; operating humidity 10%–90% RH non-condensing; altitude up to 5,000 m.
• Mechanical resilience: vibration 10–55 Hz, 2G; shock 5G (11 ms); MTBF ≥ 150,000 hours @ 25 °C, full load.
• Compact form factor: 210 × 80 × 31 mm; weight ~700 g.
• Cooling: ventilation cooling; recommended burn-in with heatsink at 40 °C and 220 VAC for production validation.
