YBBOTT DC 30V-90V to 24V 20A 480W Waterproof Buck Converter | IP67 DC-DC Power Supply for CNC, Solar

The YBBOTT DC 30V-90V to 24V 20A 480W Waterproof Buck Converter is built to deliver reliable step-down power in challenging environments. By accepting a broad input window and delivering a steady 24V output up to 20A, it supports demanding equipment like CNC controllers, solar charge setups, and rugged control electronics. The rugged housing and high-efficiency performance help keep systems running smoothly with minimal heat and fuss.

With a transfer efficiency commonly above 95%, the unit minimizes energy waste and heat generation. The internal components are bonded with adhesive and housed in an aluminum alloy enclosure, and the design relies on natural heat dissipation for quiet, maintenance-free operation. This combination makes the converter a durable option in outdoor, workshop, or vehicle-mounted installations.

Key capabilities

• Input range 30V–90V; output 24V; up to 20A (480W) max for versatile power delivery.
• Efficiency above 95% reduces waste heat and supports stable system performance.
• Rugged construction with an aluminum enclosure and solid bonding for reliable use in dusty, wet, or vibrating settings.
• Comprehensive protections include short-circuit, overcurrent, overtemperature, input reverse, overvoltage, and undervoltage safeguards; IP67 waterproof rating.
• Easy wiring with clear polarity (red positive, black negative) and a 90° entry option for tight spaces.
• Compact, shockproof, waterproof, and dustproof design suitable for a wide range of installations.

Design and reliability

The unit is designed to endure demanding environments while keeping heat under control through natural convection. The combination of an internal glue bond and an aluminum outer shell provides structural stability and long-term protection against moisture, dust, and physical stress. Its compact footprint makes it easy to integrate into CNC control cabinets, portable power setups, or vehicle-mounted electronics.

Typical applications

• LED lighting installations and strips requiring a stable 24V supply.
• Monitoring and control systems that rely on a dependable 24V rail.
• Golf carts, solar panels, and other mobile platforms that demand rugged DC-DC conversion.
• Vehicle headlights, speakers, and other electronics operating from higher-voltage sources.

Usage notes: Store in a cool, dry place away from corrosive substances and heat sources; avoid direct connection to 220V mains; do not disassemble unless qualified; ensure proper wiring polarity during installation.
