The Samlex SDC12 Switch Mode Voltage Converter is a compact, high-efficiency DC-DC converter that steps down 24 VDC to 12 VDC at up to 12 A output for use in trucks, buses, and other 24-volt vehicle systems. Its ultra-compact design and screw-terminal wiring make installation in tight engine-bay or cab locations straightforward, while built-in protection circuitry ensures reliable, long-lasting operation.

Product Features:

• 12 A output at 12 VDC from a 24 VDC input, ideal for powering radios, mobile phone kits, auxiliary lights, and other 12 V accessories.
• High efficiency up to 92% minimizes heat generation and maximizes battery life under load.
• Wide input voltage window (20–32 VDC) maintains a steady 12 V output during cranking and alternator voltage spikes.
• Built-in overvoltage, over-temperature, and short-circuit protection safeguards both the converter and connected equipment.
• Provides spike suppression to protect sensitive electronics against transient voltage surges.
• Low-noise design supports interference-sensitive devices such as communication and audio systems.
• Lightweight, ultra-compact housing fits under dash panels, on bulkheads, or within equipment racks.
• SDC20 and SDC30 variants can also function as 13.8 VDC battery chargers for 12 V starter or accessory batteries.

Application Areas:

• Stepping down 24 VDC to 12 VDC for powering radios, lighting, and mobile accessories in commercial vehicles.
• Charging 12 V starter or auxiliary batteries when using the SDC20/SDC30 charger models.
• Supplying stable 12 V power to GPS units, control modules, and in-vehicle electronics in trucks, buses, RVs, and specialty vehicles.
• Marine and RV installations requiring protected DC-DC conversion in confined or wet environments.
• Industrial and agricultural machinery where reliable 12 V supply is critical for sensors, controls, and communication equipment.

In the Box:

• 1 × Samlex SDC12 Switch Mode Voltage Converter (24 V → 12 V, 12 A).
• Mounting hardware kit (screws and insulated standoffs).
