Adjustable Boost Converter 30V 4A LCD

Unit dimensions: 79 mm (L) × 43 mm (W) × 26 mm (H) / 3.1 × 1.7 × 1 in; required panel aperture: 71 × 39 mm / 2.8 × 1.5 in. Enclosure: ABS front panel and aluminium heat-dissipating base. Input range: 5.0–30 V DC. Output voltage: digitally adjustable from 0.5 to 30 V DC. Output current limit: 0–4 A; stable continuous output at 3 A; 4 A achievable with active or enhanced passive cooling. Max output power: 35 W (natural convection), 50 W (with improved heat dissipation). Voltage measurement resolution: 0.01 V; current: 0.001 A. Typical efficiency: ~88%. Operating frequency: 180 kHz. Soft-start included (may not initiate under high-capacitance or high-inrush loads). Built-in protections: input reverse polarity survivability (no component stress), output anti-reflux (backfeed prevention), adjustable input undervoltage lockout (4.8–30 V), adjustable output overvoltage (0.5–31 V), adjustable overcurrent (0–4.1 A), adjustable overpower (0–50 W), adjustable thermal cutoff (80–110 °C), timeout setting (0–100 h, disabled by default), and overcapacity cutoff (0–60 Ah, disabled by default). Low-noise output ensured by π-type filtering and regulated feedback loop. Targeted at advanced makers, repair technicians, and R&D teams needing a compact, self-monitoring, and highly adaptable DC-DC booster — especially for renewable energy interfaces, embedded system power rails, or portable equipment upgrades.
