Samlex PST-300-24 - 300W 24V Pure Sine Wave Inverter, Cables Included

Operators of 24 volt machines carry the same laptops and chargers as everyone else; they just have fewer inverters to choose from. The Samlex PST-300-24 is a 24V 300 watt inverter built for that gap: true sine wave 120VAC from a ground-fault protected duplex outlet, a 20 amp maximum draw the machine will never notice, and both connection cables, battery clamps and accessory-socket plug, in the box. It weighs 3.46 pounds and lives wherever the operator does.

Warranty

Warranty. Samlex America warrants the PST-300-24 for 3 years. Full terms are confirmed in writing with your quote.

Pocket-Scale Power for 24V Systems

Rare at this voltage
Small pure sine inverters for 24 volt systems are thin on the ground; this one brings the full PST protection set to the operator's cab.
Connected two ways
Clamp straight to the batteries for full output, or use the included socket-plug lead for grab-and-go duty.
89% peak efficiency
The most efficient conversion in the small PST class, with under 400 milliamps of idle draw on the 24V side.
  • True sine wave output, under 3% distortion, regulated to 120 VAC within 3 percent.
  • Universal Protection Circuit with LED indicators: voltage extremes, overload, short circuit, over-temperature.
  • Remote on/off input for ignition or switch control in fixed installs.
  • ETL listed to UL 458 and CSA C22.2 No. 107.1; FCC Part 15(B) Class B.

Where This Inverter Is Used

  • Heavy equipment cabs - the operator's laptop and chargers on a 24V machine.
  • 24V trucks and buses - small electronics without a voltage dropper.
  • Field service on 24V plants - meters and instrument chargers at the site.
  • 24V emergency kits - phones and radios from the system battery.

Ordering

One box, done. Cables included, no kit required. If the loads run past small electronics, the PST-600-24 doubles the budget on the same 24V bank. Crew and kit quantities get a written quote in 24 to 48 hours with your count and ZIP.

Frequently Asked Questions

Is this the 24 volt version of the PST-300-12?

Yes: same compact chassis, same protected duplex outlet, same pair of included cables. The input window shifts to 21 to 33 VDC, the maximum draw drops to 20 amps, and peak efficiency edges up to 89 percent.

What cables come with it?

Two detachable DC leads: one with battery clamps for a direct connection, and one with a plug adapter for a vehicle accessory socket. On a 24 volt truck or machine, that socket carries the 24V this inverter expects.

What will it power from a 24V machine or truck?

The operator's electronics: a laptop, a tablet or phone charger, a small monitor or radio charger, up to 2.54 amps of AC output with a 500 watt surge allowance for switch-on. Heaters and motorized loads are out of scope at this size.

Does it need an install kit?

No. With a 20 amp maximum draw and both cables in the box, there is nothing else to buy; keep the clamp connections clean and the lead short, and it is done.

The small sine inverter 24V operators actually get.
