General Features

Type of Inverter
This is the way in which the power inverter will convert the power.

AC to DC: Converts common household AC power to DC Power.

DC to AC: Converts DC power to the common household AC power. Often times these converters can be plugged into the vehicles cigarette lighter.

AC to DC
Sine Wave
A true sine wave inverter will convert the power produced by your vehicle in a true sine wave. This allows for a cleaner power output with less distortion and will allow larger items like appliances to run cooler and quieter. A modified since wave inverter will not convert the power from your car and are typically only suited for smaller items such as fans or lights. If you're planning on hooking up items such as laptops/computers, game consoles or appliances, you want to use a true sine wave inverter.
Number of Power Outlets
This is the total number of outlets that the power inverter, power strip, or other power device has.
USB Port
This means that the item has a USB port. The port can be used to provide the unit with updates or to transfer data on to it.
Fan Cooled
A great feature to have if a power inverter generates a large amount of heat. Cooling fans can help regulate the temperature to prevent the inverter from overheating (burning).
Low Battery Shutdown
When the voltage in the vehicle drops below a certain point, the inverter will automatically shut itself off so prevent the vehicle battery from dying.
Rack Mountable
Some units can be mounted to a rack for organization and convenience.
Battery Cables Included
Battery cables included means that the unit comes with battery cables and clips to connect the unit to the vehicle's battery.

Our Model Club has used the Pyramid PS52KX to recharge batteries for our electric powered R/C airplanes for the past 4 years. We get the most for our money with the PS53KX.

Excellent power supply that is very affordable

November 21, 2012

We have 3 of these in the laboratory for testing ABS controllers after remanufacture. They work great. My only suggestion to Pyramid would be to add a current limiting control. That way if the device we are connecting has an internal problem, current limiting will protect the component under test/power from further damage. 12V at 50 amps from this monster power supply will easily vaporize traces off a shorted circuit board.

So we test the control boards on a 2 amp supply. When they pass, get installed into the ABS hydraulic unit with motor and solenoids. Then that entire assembly goes to the PS52's on their rack for full load testing.

Transformer is very hefty as is the rectifier pack. This is not a mil spec item, so don't expect construction of that caliber. This product was intended to be affordable for consumer use. For the price, these are a great value and have proven to be reliable for our moderate industrial-duty application.

My primary quality concern for this unit (price being as low as it is) are the capacitors and their quality. I didn't open to see what brand they use. But we have not encountered any issues. Power is regulated perfectly and no ripple even at near maximum load.

Verified Purchase
Durable and handy

December 6, 2016

This is the second PS 52 KX I've owned. I used the original for about 5 years and then it got placed on the shelf where it sat for about 11 years. It performed flawlessly from the first time I used it. When I took it off the shelf, all I had to do was replace some capacitors and it was good to go. I like the unit so much that I bought another one. The price is right and delivery very fast. It's a great addition to my ham shack.
