<h3>About Samlex America</h3><p>Founded in 1991 and headquartered in Burnaby, British Columbia, <strong>Samlex America</strong> has grown into one of the most respected names in power conversion technology. With a commercial footprint spanning more than 90 countries, Samlex serves a remarkably wide range of industries — from communications and mobile fleet management to marine, RV, off-road, and fixed off-grid installations. Whether you need to power sensitive electronics in a remote cabin or keep a commercial work truck running smoothly in the field, Samlex engineers a solution built to last.</p><h3>A Complete Power Conversion Lineup</h3><p>What sets Samlex apart from one-trick-pony manufacturers is the sheer breadth and integration of their product ecosystem. Their catalog spans AC-DC power supplies, DC-DC voltage converters, solar panels and kits, battery accessories, transfer switches, and solar charge controllers. At the heart of the lineup, however, are two product families that have earned Samlex its stellar industry reputation: <a href="/7541-samlex-power-inverter-14297">power inverters</a> and <a href="/7541-samlex-battery-charger-14307">battery chargers</a>.</p><p><a href="/7541-samlex-power-inverter-14297">Samlex power inverters</a> are available in both pure sine wave and modified sine wave configurations, covering an enormous range of wattage requirements. Pure sine wave models — like the flagship NTX and EVO&trade; Series — deliver power that is virtually identical in quality to utility grid power, making them ideal for sensitive electronics, medical devices, and modern appliances. For users who need dependable DC-to-AC conversion in RVs, boats, or work vehicles, Samlex inverters are a go-to choice trusted by engineers and hobbyists alike.</p><p>On the charging side, <a href="/7541-samlex-battery-charger-14307">Samlex battery chargers</a> employ switched-mode technology to deliver efficient, quiet, and intelligent charging across 12V and 24V platforms. Their chargers are compatible with a wide variety of battery chemistries — including flooded lead-acid, AGM, GEL, and lithium-ion — making them a versatile fit for everything from marine deep-cycle banks to off-grid energy storage systems.</p><h3>Industries Served</h3><p>Samlex&apos;s versatility is one of its most compelling traits. Their products are deployed across an impressive range of real-world applications:</p><ul><li><strong>RV &amp; Camping:</strong> Stay powered on the road or at the campsite without relying on shore power or noisy generators.</li><li><strong>Marine:</strong> Reliable power conversion for onboard electronics, navigation systems, and creature comforts on the water.</li><li><strong>Mobile Fleet &amp; Work Trucks:</strong> Keep tools, lighting, and communication equipment running efficiently from your vehicle&apos;s battery system.</li><li><strong>Fixed Off-Grid:</strong> Pair Samlex inverters and chargers with solar panels for a complete, self-sufficient energy system.</li><li><strong>Communications:</strong> Mission-critical backup power for radio base stations, repeaters, and 24/7 communication infrastructure.</li><li><strong>OEM &amp; Commercial:</strong> Custom power solutions built to specification for industrial and commercial integration projects.</li></ul><h3>Built on a Foundation of Reliability</h3><p>Samlex&apos;s commitment to engineering quality is evident in the protection features baked into their products. Many units include multiple layers of fault monitoring — scanning for adverse conditions thousands of times per second — along with thermal management systems that activate cooling only when necessary to reduce noise and energy draw. It&apos;s this level of attention to detail that has made Samlex a trusted partner for demanding commercial and industrial markets worldwide for over three decades.</p>

Product Details

The Samlex SDC-5 is a high-efficiency switching DC-DC converter designed to step down 24 VDC nominal input (range 20-32 VDC) to a highly regulated 13.8 VDC output at 5 amps continuous. This non-isolated converter features advanced switch-mode technology for reliable voltage conversion in negative ground systems commonly found in trucks, buses, marine vessels, and heavy equipment.

Key Features:

  • Advanced switch-mode design with high efficiency for minimal heat generation
  • Comprehensive protection: reverse polarity, overvoltage, short circuit, and input transient protection
  • Temperature-compensated current limiting circuit for safe operation
  • Cycle-by-cycle current limiting prevents damage during overload conditions
  • Compact, lightweight design allows mounting in nearly any location
  • Output-side and input-side overvoltage protection for added reliability

Technical Specifications:

  • Input Voltage: 20-32 VDC (24V nominal)
  • Output Voltage: 13.8 VDC regulated
  • Output Current: 5 Amps continuous
  • Dimensions: 3.5" L × 2.75" W × 1.75" H
  • Weight: 0.4 lbs
  • Warranty: 2 Year Limited

Ideal Applications:

  • Heavy-duty trucks and buses with 24V electrical systems
  • Earth-moving and construction equipment
  • Marine vessels requiring 12V accessories
  • CB radios and AM/FM sound systems in commercial vehicles
  • 12-volt lighting systems and electronics in 24V vehicles

The SDC-5 provides a reliable solution for powering 12-volt devices and accessories in 24-volt vehicle electrical systems, with robust protection features for demanding commercial and marine environments.

paypal hard to use

Very easy

price seems okay . .

Great company to deal with. I placed an order with them (albeit an incorrect shipping address) and before you know it I'm expecting delivery in a very short amount of time. I also did have to call and attempt to correct my address error when the customer service rep let me know that all is well and set to be delivered to the correct address. I appreciate the fact that the gentleman on the other end of the phone was reassuring, courteous, and professional. I'd certainly do business with them again as the prices and customer service can't be beat!

Love shopping here, I always find what I need.

Easy fast

Best prices I have found. They got me a tracking number within 2 business days. Can't wait for my goods to arrive. Will be using this site again for sure.

Lowest price around with fast shipping. I would recommend this to a friend.<br><br><br>

great prices

so far - so good
