DC DC Step Down Converter, 48V to 24V

The DC-DC buck converter steps down 48V to 24V with 3A-63A output options, offering 32-60V input range, up to 96% efficiency, and a 120W max power (at 5A). It features full-power stable output, uses premium components like Rubycon, Panasonic, and TI, and is fully potted with thermal silicone for IP68-rated waterproof, dustproof, and shockproof protection. Built-in safety includes overcurrent, overvoltage, overtemperature, short circuit, and undervoltage protection. Ideal for EVs, industrial automation, telecom, solar systems, and other 24V equipment powered from 48V sources.

Feature

• Non-isolated DC voltage regulator module.
• 100% full power output with high stability.
• Built with 100% components (e.g., Rubycon, Panasonic, TI), with 92–96% efficiency.
• Buck to buck converter fully potted with high-quality imported thermal silicone; IP68 waterproof, dustproof, shockproof; compact die-cast aluminum housing, easy to install.
• Wide voltage input with built-in protections: over-current, over-voltage, over-temperature, and short-circuit.

Details

1. Overcurrent Protection: Output voltage gradually drops to zero when output current exceeds the set limit (common in inductive loads like motors or pumps).
2. Overtemperature Protection: When the chip temperature exceeds 150°C, the converter stops working and shuts down output.
   (Note: Refers to chip temperature, not ambient temperature.)
3. Short Circuit Protection: Instant short circuit at the output terminals will not damage the converter.
4. Waterproof Protection: The DC DC step down converter adopts waterproof potting design for moisture, dust, and shock resistance.
5. Undervoltage Protection: When input voltage drops below the set threshold, the output voltage gradually decreases until shutoff.
   (Note: Helps prevent battery over-discharge and extends battery life.)
