Tripp Lite LC1200 1200W Line Conditioner w/ IsPRar Protection 4 outlets 120V Review

June 29, 2007

We purchased a Tripp-Lite model LC1200 wide-range AVR when the voltage tolerance of an Ultra Products model ULT33045 power protector proved inadequate to cope with our local power conditions. Inserted between the line power outlet and the Ultra, the Tripp-Lite adds enough boost-buck range to cope. We draw 100-250 W through the pair, well below rated capacity of both these units.

At 85 VAC line voltage, the combination boosts to 114 VAC, remaining within 5% tolerance with respect to 120 VAC usually recommended for the most reliable operation of electronic equipment. Observing performance over time, we find that the combination maintains 5% tolerance about 90 percent of the time and 10% tolerance all the time. We would probably not be able to obtain this quality of regulation with the Tripp-Lite alone, because its large voltage steps, 9-10 percent.

As of late June, 2007, Tripp-Lite has changed LC1200 specifications slightly since those shown here, promising regulation of 120 VAC to within -12% with input of 89 VAC. Newer units have black rather than white or gray cases.

The Tripp-Lite does not disconnect when line voltage goes lower, at least down to 85 VAC, but its maximum boost remains about 19 percent. It has a plastic hardshell case, not metal, but remains fairly cool. There is no appreciable magnetic shielding, Working near a ViewSonic P225 21-inch CRT monitor, we found that with the centers of the ViewSonic and Tripp-Lite in the same plane, the distance between the units had to be at least 0.9 m (36 in) to eliminate flicker from the Tripp-Lite's magnetic leakage.
