Regulated DC/DC converter

non-isolatedencapsulatedwaterproof

Short description
Compact non-isolated DC-DC converter that automatically boosts or bucks an 8–40V DC input to a regulated 13.8V ±0.25V output. Available in 5A–25A variants and designed for IP67 protection.

Features

• Synchronous rectification technology
• Internal low-ESR capacitor filter for high-temperature tolerance
• Organic silicone encapsulation
• Smart chip protections: over-temperature and over-current
• Shock-, drop-, moisture- and dust-resistant design
• High efficiency: typical up to 96%
• Non-isolated topology (input and output share common reference)
• Ingress protection: IP67 (waterproof)

Attention

• Follow label instructions for installation; do not reverse polarity (positive/negative), otherwise the module and components may be damaged
• Do not connect input and output in reverse; device may be damaged
• Ensure load power does not exceed the converter's maximum rated power
