Product Details

The Samlex SDC-30 is a high-efficiency switch-mode step-down DC-DC converter designed to convert 24 VDC nominal input (range 20-32 VDC) to a precisely regulated 13.8 VDC output at 30 Amps continuous. This non-isolated converter is engineered for negative ground systems and provides reliable power conversion for trucks, buses, marine vessels, and heavy equipment operating on 24V electrical systems while powering 12V accessories and electronics.

Key Features:

  • Advanced switch-mode technology delivers high efficiency and minimal heat generation
  • 30A continuous output capacity at 13.8 VDC regulated output voltage
  • Wide input voltage range: 20-32 VDC accommodates voltage fluctuations
  • Comprehensive protection: reverse polarity, overload, over-voltage, over-heating, and short circuit
  • Cycle-by-cycle current limiting prevents damage during overload conditions
  • Compact, lightweight design (1.2 lbs) mounts in tight spaces
  • Non-isolated design optimized for cost-effective negative ground applications

Technical Specifications:

  • Input Voltage: 20-32 VDC (24V nominal)
  • Output Voltage: 13.8 VDC regulated
  • Maximum Continuous Current: 30 Amps
  • Dimensions: 6.0" L × 3.5" W × 1.9" H
  • Weight: 1.2 lbs
  • Warranty: 2-Year Limited Manufacturer Warranty

Common Applications:

  • Heavy trucks and commercial vehicles with 24V electrical systems
  • Buses and transit vehicles powering 12V accessories
  • Marine vessels and work boats
  • Construction and earth-moving equipment
  • CB radios, AM/FM audio systems, and communication equipment
  • 12V LED lighting systems and auxiliary power

Ideal for converting 24V battery bank power to reliable 12V DC for accessories, electronics, and lighting in commercial vehicles, marine applications, and industrial equipment.

First time ordering, but not the last. Everything perfect...Thanks

Super fast website. Easy checkout for new customers. Best Price from a reputable site. Good job.

way cheaper than everywhere else. Lets hope the product is good!

Good.

Fast Shipping, Great price, Parts were well packed

Quick, easy, and fast

Excellent prices, but after a week and a half of hearing nothing I called to find out that my item, the customer service rep said it had been back ordered and I would receive an email once it shipped...my item arrived the next day and I received the shipping email four days later, no big deal just takes a while to get items, but you cannot beat the prices!

So far good.

Very easy !

Very good first experience with Autoplicity. Order arrived promptly. No issues.

I had never heard of Autoplicity prior to this purchase, so I was a little hesitant to order from them. Man I am glad that I did!! Not only did they have the lowest price (by FAR) on the product I was looking for, but it showed up to my doorstep just TWO days after placing my order!! Autoplicity is awesome and will definitely be getting future business from me!!

Wow super fast shipping and I ordered over a holiday weekend. Will be doing business with this site again soon.
