Samlex PSE-12125A 1250W portable power inverter

SKU CH-MWG3-NVRWP

Converts 12 VDC to 115 VAC with 1250 W continuous and 2250 W intermittent output, modified sine wave, two AC outlets and overload protection

  • Delivers 1250 W continuous AC power from a 12 VDC source
  • Handles brief 2250 W surges for motor-driven tools and appliances
  • Two 115 VAC outlets let you run multiple devices at once
  • LED indicators show operating status at a glance
  • Optional 36883 remote switch adds convenient off-board control

Portable 1250 W inverter for 12 V systems

The Samlex PSE-12125A converts 10 to 15 VDC into 115 VAC at 60 Hz, delivering 1250 W continuous power from a vehicle, boat or camper battery. Two AC outlets let you run home electronics, computers, monitors or tools wherever a 12 V source is available. A modified sine-wave output suits resistive and many switched-mode loads.

1250 W continuous versus 2250 W intermittent

The single figure that decides fit is the 1250 W continuous rating; loads that exceed this level will trip the overload protection even though the unit can handle 2250 W for short bursts. Match the total draw of connected devices to the continuous number, not the peak.

Thermal behaviour under sustained load

When operated near 1250 W for extended periods the inverter relies on its internal protection to prevent overheating, so duty cycles should allow cooling intervals. Continuous full-load running without airflow will trigger shutdown before the intermittent rating can be used again.

Not for pure-sine-sensitive equipment

Medical devices, audio gear and certain motor-driven appliances that require a true sine wave are not supported by the modified wave output. Buyers needing grid-quality waveform should select a pure-sine model instead.

Questions about this item

How much AC power can the 1250 W continuous rating actually deliver to tools and electronics?

The inverter supplies 1250 W continuously and up to 2250 W intermittently from its two 115 V AC outlets, enough for typical home electronics, monitors and small tools.

What does the 10–15 V DC input range mean for connecting to a vehicle or battery bank?

It accepts 10 to 15 V DC, so it runs directly from a 12 V car, boat or camper battery without extra converters.

Will the 11 × 8 × 2.75 inch case fit in my vehicle’s storage compartment?

The unit measures 11 inches long, 8 inches wide and 2.75 inches high, so check those dimensions against your available space.
