Overview

The Universal 71637 was marketed for protection of personal computers and related office equipment. In addition to protecting connected AC-powered devices, the unit provides surge protection for telephone lines used by modems, fax machines, and telephones. The example documented by OldSurge was tested and found to be operational, with all outlets indicating correct wiring when checked with a receptacle tester.

The built-in "Protection Indicator" lamp provides a visual indication that surge protection circuitry is operational.

The Universal 71637 incorporates a "Power Shut Down Protection" feature. According to the product labeling, once the surge suppression components have absorbed their protective capacity, the device will stop conducting power rather than continue operation without protection.

Physical Description

Physical Description

The Universal 71637 features a two-level stepped housing finished in off-white plastic. A raised section at one end contains the illuminated resettable circuit breaker / power switch, protection indicator, and product branding.

The unit measures approximately 7.75 inches long by 3.5 inches wide. The housing height tapers from approximately 1.5 inches at the switch section to approximately 1.19 inches at the outlet section.

An attached power cord approximately six feet in length provides flexibility for placement around desks and computer workstations.

The underside of the enclosure incorporates two sets of keyhole mounting slots arranged at 90 degrees to one another, allowing the unit to be mounted either horizontally or vertically on a wall or other flat surface.

The documented example weighs approximately 1 pound 3.7 ounces including the attached power cord.

Notable Features

The Universal 71637 incorporates a "Power Shut Down Protection" feature. According to the product labeling, the unit will stop conducting power after its surge suppression components have reached the end of their protective life. This design prevents continued operation without surge protection.

The underside of the enclosure includes integrated keyhole mounting slots for wall installation.

The unit is rated as a UL Listed Relocatable Power Tap and carries a UL 1449 suppressed voltage rating of 330 volts.
