(IMPORTANT!!!)
I've had this for quite a few years now, that's why it does not look brand spanken new in the above photograph!!!

This product does not emit light of its own, so the standard review format will not be used and the product will not be assigned a rating.


The Energy One XP-4 Power Supply is a benchtop power supply that has three fixed outputs and one variable output.

Two of the fixed outputs are +5 volts and -5 volts; these are handy for powering TTL IC chips and similar; the other fixed output is +12 volts -- useful for powering automotive electronics without the need to be near an automobile, and the variable output (variable with nothing more than a simple knob) allows you to select any voltage from +0.001 volts up to approximately +13 volts.

The current sinking ability appears to be approximately 1,000mA (1.00 amp).

This variable voltage output is what I use (by far!) most frequently; it is useful for testing LEDs (surprise surprise surprise...NOT!!!) that either will not fit the receptacles of any of my LED testers, or require voltages or currents that cannot be furnished by my LED testers.


Size of product w/hand to show scale SIZE



To use the XP-4, first you'll want to plug it in to a standard (in north America anyway) 110 volts to 130 volts AC 60Hz 3-slot household receptacle (or "electrical outlet" or even "wall socket" if you prefer). Turn it on using the rocker switch located near the lower left of the unit's face.

For +12 volts (for testing automotive products), plug a pair of leads terminated in male banana plugs into the two receptacles just below and to the right of the meter face, labelled "+12" and "COM". Red receptacle is (+) positive, black receptacle is (-) negative.

To supply power to TTL ICs (that need +5 volts and/or -5 volts), plug a pair of leads terminated in male banana plugs into the rightmost receptacles: black receptacle is (-) negative, green receptacle is +5 volts, and yellow receptacle is -5 volts.

To obtain variable voltages from +0 volts to over +12 volts, plug a pair of leads terminated in male banana plugs into the two leftmost receptacles on the face of the power supply -- as usual, red is (+) is positive, black is (-) negative. You can then adjust the voltage using the knob near the upper right face of this PSU (power supply unit).

When you are finished using this PSU, turn it off with its rocker switch -- again, located near the lower left of the unit's face.



This is a power supply unit, not a flashlight designed to be thrashed, trashed, and abused. So I won't throw it against the wall, stomp on it, try to drown it in the toylet bowl or the cistern, run over it, swing it against the concrete floor of a patio, use a ball peen hammer in order to bash it open to check it for candiosity, fire it from the cannoņata, drop it down the top of Mt. Erupto (I guess I've been watching the TV program "Viva Piņata" too much again - candiosity is usually checked with a laser-type device on a platform with a large readout (located at Piņata Central aka. Party Central), with a handheld wand that Langston Lickatoad uses, or with a pack-of-cards-sized device that Fergy Fudgehog uses; the cannoņata (also located at Piņata Central) is only used to shoot piņatas to piņata parties away from picturesque Piņata Island, and Mt. Erupto is an active volcano on Piņata Island {In the episode "Les Saves the Day...Again", Paulie Preztail says "Hey, ever wonder why this park's called 'Mount Erupto' anyway?", then Franklin Fizzlybear says "I think its an old native term. Means 'very safe.'"}), send it to the Daystrom Institute for additional analysis, or inflict upon it punishments that flashlights may have inflicted upon them.

Here are the measurements:

The variable output was measured to have a range of +0.00 volts to +13.110 volts
The fixed +12 volt output was measured at +12.170 volts
The fixed +5 volt output was measured at +5.110 volts
The fixed -5 volt output was measured at -5.010 volts.


TEST NOTES:
Power supply was donated by a kind CPF member in 2000 or 2001.

It is not known where this product was made.
A product's country of origin really does matter to some people, which is why I wanted to publish it on this web page.
