Product Details

The Samlex SDC-23 is a high-efficiency switching DC-DC converter that steps down 24 VDC nominal voltage (input range 20-35 VDC) to a precisely regulated 13.8 VDC output at 20 amps continuous. This non-isolated converter is designed for negative ground systems and delivers reliable power conversion for heavy-duty applications in commercial vehicles, marine systems, and industrial equipment.

Key Features:

  • Advanced switch-mode technology for high efficiency and minimal heat generation
  • Comprehensive protection: reverse polarity, overvoltage, short-circuit, and transient protection
  • Temperature-compensated current limiting prevents damage during overload conditions
  • Overvoltage crowbar circuit on output side for connected equipment protection
  • Compact, lightweight design allows flexible mounting in tight spaces
  • Non-isolated design optimized for negative ground systems

Technical Specifications:

  • Input voltage: 20-30 VDC (nominal 24 VDC, maximum 35 VDC)
  • Output voltage: 13.8 VDC (regulated)
  • Continuous output current: 20 amps
  • Dimensions: 7.75" L × 4.75" W × 2.4" H
  • Weight: 2.2 lbs
  • Warranty: 2 years limited

Ideal Applications:

  • Heavy trucks, buses, and earth-moving equipment with 24V electrical systems
  • Marine vessels requiring 12V accessories on 24V platforms
  • CB radios and AM/FM sound systems
  • 12-volt lighting systems and auxiliary equipment

This rugged converter provides reliable power conversion for demanding environments where equipment operates on 12V systems but primary power is 24V. Perfect for fleet vehicles, commercial marine applications, and industrial machinery.

Found the item via Amazon, at a lower price than Amazom, and Paid via my Amazon account. Quick, easy, and less expensive. I shall return!

Good

Best Price

Although you don't offer free shipping to Alaska at least you will ship and not charge extortionate rates. I was astonished how quickly it arrived.

Great just what I wanted.

exellent

Lowest price on the web, great deals, easy transactions. They got Paypal set up so you if you have an account with them makes it a flash to pay. Super site

The site seems very quick and easy to use

Quick and easy so far hopefully parts are what I need

Your prices for Metal Rescue were the best I could find and your shipping was fast, although I screwed up and ordered a quart when I though I ordered a gallon

Great Parts.Great Service.Thank you.

Great service, and the best price. I had the item in a week thanks guys.

I purchased a Volant Cool Air Intake Kit for my truck. Autoplicity had the best prices by far! Shipping costs were very reasonable and my order shipped quickly. I'll order more from them in the future.
