The Quad XP-581 from Elenco provides four separate, fully regulated power supplies. Three are fixed and yield +5 VDC at 3 amps, -12 VDC at 1 amp, or +12 VDC at 1 amp. The fourth supply is variable, producing 2.5 to 20 volts of DC output at up to 2 amps. Line and output voltages are regulated to within 0.05 volts, and the supply is linear. All four supplies are shortproof as well. A current foldback circuit in each supply collapses the field in the event of a short, a current surge from the line, or an excessive current demand. Thus, both the Quad XP-580 and the equipment it's driving are normally protected from inadvertent errors or power company problems. Elenco built the supply as only Elenco will. The handsome, hooded metal case, - measuring 3-1/4" x 8-1/4" x 9-1/4" and weighing nine pounds - has a 3-wire grounded power cord for 115 VAC operation, panel meters for both current and voltage, and standard jacks for accessing the four regulated supplies. A two-year limited warranty and schematic is also included.

There is an entire class of transformers that surplus dealers call "AC Adapters." What we really mean is transformers that plug directly into the wall (primary voltage 110 VAC), and via a cord and/or plug provide various levels of output current at variou s voltages. It is a rare buyer of surplus that gets the plug configuration he/she wants, and many get snipped off (plugs that is). They are handy power supplies, battery charging units, substitutes for batteries in toys and games, or for providing safe il lumination to models and displays. Be sure to note whether the output is AC or DC (Direct Current, like a battery) and whether it can provide enough current for your application. Unless otherwise noted, all are suitable for indoor use only. Stick with us and you'll get the hang of adapting to AC...and at much lower prices than your friendly appliance/game/computer/calculator shop asks. Unless otherwise noted, all adapters are for 115 volt AC primaries, and all have about 6 ft. cords. (MA=Milliamp) (A=Ampere) (VDC= Volts DC) (VAC= Volts AC).

And teach a kid (8 and up) the basics of solar power. This excellent educational kit comes with (9) 0.5VDC solar cells pre-wired in sets of (3) and mounted in a 5" x 4" x 7/16" black-plastic frame with screw terminals on the bottom. The kit includes a 1.5VDC motor with leads and a mount, a fan blade and (4) plastic discs from 5/8" dia to 2" dia for mounting on the motor shaft, a 1.5V incandescent bulb with leads, a sound module with leads, and graphic cards to mount on the discs. Comes with a 14-page instruction/experiment booklet, including info on increasing voltage and amperage, powering battery charges, radios, games, etc. Lots of science project potential. "Heuristic as all get-out," Jarvis said when he saw it.

Or usin' it up? This nice solar cell is made to prevent battery drain in cars, boats, snowmobiles (or anything else with a 12-volt) during storage or because you're running stuff like cell phones, laptops, or various pods off of said battery. Rated for 12VDC 120mA, it measures 14-3/4" x 6-1/4" x 3/4" OA with an 11-3/4" x 4" cell. The 91" cord leads to a fused and polarity-protected cigarette-lighter plug. Has 14.7 VDC output with no load, an LED indicator, and weatherproof housing. Works in all weather, even low-light and cloudy conditions.
