Regulated power supply for ham qrp, laptop or project


WIDE INPUT: 100-240 VAC 50-60 Hz @ ~ 0.4 Amp
** Output Voltage CAN BE MODIFIED (click here) **
This is NOT a cheap 'wall-wart'
Professional, computer grade, regulated power supply. Designed for laptop computers and other critical applications, this inexpensive supply is suitable for all kinds of equipment and home projects. And, unlike most linear wall-warts, this switching supply is very efficient, barely warming under a continuous full load..
* Full voltage regulation @ 0 to 100% load
Most wall-warts are inefficient and
* Automatically adapts to any world-wide
input between 100 - 240 VAC and 50 - 60 Hz
No switches or straps to set
No droop in output during brown-outs
* Compact, Lightweight and Rugged case
Approximately 6 oz. and 1 x 2 x 4 inches
Cheap wall-warts are heavy and ugly
* Standard AC power cord (Included)
Cheap wall-warts crowd out adjacent
* UL and CSA Rated (and other standards)

The perfect cornerstone for a simple, multiple voltage, bench/utility supply. Wire the output directly to one set of binding posts and then add some 78xx or 79xx series regulators to create multiple outputs. Better still, use an LM317 and make a simple dual supply with one fixed and one variable output. The possibilities are endless.
Tested under full load to verify operation before packing. 14 day non-DOA guarantee.
Output cable is a shielded, unconnectorized, 18 inch 'pigtail' ready for wiring.
** Output Voltage Modification **
Caution: Modifications of any kind will void our 14 day non-DOA guarantee. That said, this supply has a fixed output, but can be easily modified by an experienced technician to produce an output voltage (fixed or even adjustable) slightly higher or lower than nominal if, for example, you need 12 or 13.8 VDC. It only takes one trimmer (or two fixed resistors) and optionally changing or removing a zener diode to do the trick. (The trimmer/resistors make a voltage divider similar to LM317 circuits and the zener is an optional voltage clamp.) If you are interested in the details, contact us for additional information. But please understand that since we have no control over the accuracy of your work, modifying your supply voids our 14 day non-DOA guarantee. Modified supplies are not returnable for refund.
