  • Steps 12-18V input up to 24V 7A output
  • Switch-mode design delivers high efficiency power conversion
  • Built-in over-current and over-voltage protection safeguards equipment
  • Reverse polarity protection prevents damage from wiring errors
  • 3 mm push-on flat pin connectors enable quick installation

Samlex STEP-7 12-18V to 24V 7A Converter

The Samlex STEP-7 is a switch-mode DC-DC step-up converter that raises a 9-18 VDC input to a regulated 24 VDC output at 7 amps. It is built for industrial, commercial, OEM, recreational and marine environments where 24 volt equipment must run from a 12 volt source. CE approval and protections against over-current, over-voltage and reverse polarity support reliable operation. Compact dimensions of 3.5 by 3.9 by 1.9 inches allow installation in tight spaces.

Suitable Applications and Limits

This unit suits installers who need to power 24 volt loads such as pumps, radios or lighting from a 12 volt vehicle or battery system. The 7 amp continuous rating fits moderate-demand devices. Buyers who need more output current or a wider input range should look at a different model. It is not a battery charger and cannot step voltage down.

7 Amp Output at 24 Volts

The converter delivers a maximum of 7 amps at 24 VDC, which is the single figure that determines whether your load can be supported. Check the total current draw of all connected devices against this limit before purchase. The 6.3 mm push-on flat pin connectors provide the electrical interface.

Questions about this item

What are the connector sizes for the 6.3 mm push-on flat pins on the STEP-7?

The unit uses 6.3 mm push-on flat pin connectors for both input and output wiring.

How do I wire the STEP-7 correctly to avoid reverse polarity damage?

Connect the input leads to a 9-18 VDC source observing the marked polarity; the built-in reverse polarity protection helps prevent damage if wires are swapped.

Does the STEP-7 have any user-serviceable parts like fuses that need periodic replacement?

No user-serviceable parts are specified; the converter relies on internal over-current and over-voltage protection rather than replaceable fuses.
