The Samlex SDC05 Switch Mode Voltage Converter is a compact, high-efficiency DC-DC converter that steps down 24 V to 12 V for use in trucks, buses, and other 24-volt vehicle systems. Available in multiple current ratings, it fits virtually any mounting location and includes built-in protection circuitry for reliable, long-lasting operation. Built-in protection circuitry provides peace of mind and long-lasting performance.
Product Features:
- The SDC05 model delivers up to 5 A of stable 12 VDC output from a 24 VDC input.
- High conversion efficiency up to 92% minimizes heat generation and maximizes battery life.
- Built-in overvoltage, over-temperature, and short-circuit protection safeguards both the converter and connected equipment.
- Wide input voltage window (20–32 VDC) ensures steady output even during vehicle cranking or alternator spikes.
- Low-noise design supports sensitive electronics such as radios, mobile phone kits, and auxiliary controls without interference.
- Easy-wire screw-terminal connections simplify installation in tight engine-bay or cab spaces.
- Lightweight, ultra-compact housing mounts securely on bulkheads, under dash panels, or inside equipment racks.
- The SDC20 and SDC30 variants double as 13.8 VDC battery chargers, allowing charging of a 12 V starter or accessory battery from a 24 V source.
Application Areas:
- Stepping down 24 VDC bus or truck systems to 12 V for powering radios, lights, and mobile accessories.
- Charging 12 V starter or auxiliary batteries using the SDC20/SDC30 chargers in commercial vehicles.
- Supplying stable 12 V power to sensitive electronics in emergency, utility, and public-safety vehicles.
- Integrating into marine, RV, and off-road applications where reliable DC-DC conversion is critical.
- Use in industrial machinery and control panels requiring a compact, protected 12 V supply.
In the Box:
