While utility power is notoriously unfit for computer loads, the PC╞s power supply does an admirable job of first defense. Most quality PCs already have a significant degree of isolation and filtering built-in to their power supplies. 
Line-R: High-performance power conditioning
While utility power is notoriously unfit for computer loads, the PC╞s power supply does an admirable job of first defense. Most quality PCs already have a significant degree of isolation and filtering built-in to their power supplies.
Additional protection is required against power events that either deliver much lower or much greater levels of energy than the power supply can sustain.
In anticipation of these circumstances, proper protection of loads is essential. This graph shows that the Line-RTM completely protects PCs by regulating incoming AC voltage to within the limits of safe computer operation.
Many sites have gross variations in line voltage and need a cost-effective solution to correct chronic brownouts and overvoltages. Using a Line-R, you can continue working through brownouts or overvoltages all day long, if necessary, without interruption or data loss.
The Line-R is a microprocessor-controlled tap changing power conditioner which automatically corrects brownouts (by boosting low voltage), and overvoltages (by stepping down high voltage) to levels that are safe for your system.
Single technology surge suppression often stops only one type of transient. For instance, it may stop spikes, but have trouble with surges or EMI. Unlike typical single MOV or diode based suppression, Line-R╞s multi-stage design handles all the problems your equipment is likely to face.
A voltage meter on the Line-R╞s front panel displays the relative input voltage level and alerts you to low or high voltage conditions. A front panel surge protection integrity light indicates the health of the circuitry. In addition, an audible alarm alerts you to extreme input voltages that cannot be corrected to within the normal output voltage regulation band.
Full-time EMI/RFI filters prevent electrical noise from affecting computer operation or corrupting your data files.
A site wiring fault indicator spots missing ground and reversed polarity, two common miswirings which usually require an electrician╞s visit to find.
The Line-R automatically performs a self-test each time you turn on the system to ensure that it is running correctly. Its ⌠adaptive mode÷ also senses and corrects frequent tap changing, thereby reducing wear on the relays for a longer lifespan and quiet operation.
Unmatched reliability means you can purchase with confidence.
UL, CSA, and TUV approvals mean a safe, reliable solution to your power problems.
For as long as you own your Line-R, if your properly connected equipment is ever damaged by an AC surge, including surges due to lightning, APC will repair or replace our product and up to $25,000 of connected equipment (US and Canada only, see policy for details).
