Samlex 200W Fully Isolated DC-DC Converter - 8A - 20-35V Input - 24V Output

The Samlex 200W Fully Isolated DC-DC Converter (model IDC-200B-24) is purpose-built for mobile power systems, auxiliary battery setups, and multi-voltage vehicle installations where electrical isolation between input and output circuits is critical. Whether you're upgrading a camper van's auxiliary system, installing a second battery bank in a truck, or powering onboard electronics from a high-voltage primary system, this converter delivers clean, regulated 24V output from 20–35V input sources. Galvanic isolation prevents ground loops and protects sensitive equipment—a must-have for modern vehicle electronics.

Built around Samlex America's proven isolated DC-DC architecture, the IDC-200B-24 uses transformer-based isolation to create complete electrical separation between primary and secondary circuits, eliminating the risk of voltage spikes damaging auxiliary devices. The unit delivers up to 8 amps at 24V output (200 watts total), with high-efficiency switching topology that minimizes heat generation and extends device lifespan. Compact dimensions (4 × 2 × 7 inches) and lightweight construction (1.45 lbs) make it ideal for space-constrained installations like under-seat mounting or battery box integration. Input voltage range of 20–35V accommodates both nominal 24V systems and tolerates alternator output swings and battery charging surges without regulation loss.

Fleet operators, RV builders, and serious truck enthusiasts rely on this converter for powering auxiliary lighting, mobile electronics, onboard winch controllers, and communication systems from isolated battery banks. The galvanic isolation feature is especially valuable in vehicles with ground-loop issues or where auxiliary systems must operate independently of the chassis electrical system. Installation requires only input power, ground return, and 24V load connections—no complex wiring or ground isolation relays needed. Samlex's industrial-grade design ensures this converter handles repeated cold-start surges and vibration environments that standard automotive converters cannot tolerate.
