PowerPig:

= Universal 71637 =

The '''Universal 71637''' is a six-outlet surge protector manufactured in 1998 and intended for home and office computer equipment.

The unit incorporates AC surge suppression and telephone line protection, reflecting the needs of the late-1990s dial-up internet era when personal computers commonly connected to telephone networks through internal or external modems.

== 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.

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

== Features ==

* Six AC outlets
* Illuminated resettable circuit breaker / power switch
* Protection status indicator
* Telephone line surge protection (RJ11 In/Out, 4-conductor)
* Approximately 6-foot attached power cord
* Grounded three-prong power plug
* Keyhole wall-mount slots
* UL 1449 surge suppression
* Power Shut Down Protection

== Specifications ==

* Model: 71637
* Year: 1998
* Country of Manufacture: China
* Voltage Rating: 125 VAC
* Current Rating: 15 Amps
* Frequency: 60 Hz
* Maximum Load: 1875 Watts
* UL 1449 Suppressed Voltage Rating: 330 Volts
* Protection Modes:
** Line-to-Neutral (L-N)
** Line-to-Ground (L-G)
** Neutral-to-Ground (N-G)
* Telephone Protection: RJ11 In/Out (4-conductor)
* Cord Length: Approximately 6 feet
* Cord Construction: 14/3 SJT, 75°C
* Plug Type: NEMA 5-15P
* Weight: Approximately 1 lb 3.7 oz (560 g)
* Length: Approximately 7.75 in (19.7 cm)
* Width: Approximately 3.5 in (8.9 cm)
* Height:
** Approximately 1.5 in (3.8 cm) at the raised switch section
** Approximately 1.19 in (3.0 cm) at the outlet section

== 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.

== Disassembly ==

The Universal 71637 enclosure is secured by seven Phillips-head screws located on the underside of the housing.

After removal of the screws, the enclosure separates into upper and lower shell halves. Internal construction consists primarily of stamped brass outlet bus bars, a dedicated surge suppression circuit board, telephone line protection circuitry, and an illuminated resettable circuit breaker / power switch assembly.

The AC outlets are interconnected using continuous stamped brass bus bars rather than individual wires. Telephone protection circuitry is located on a separate board adjacent to the RJ11 input and output jacks.

The specimen documented by OldSurge was found to be clean internally with no evidence of overheating, arcing, melted components, surge-related damage, or previous repair attempts.

=== Internal Components ===

* Seven-screw enclosure construction
* Stamped brass outlet bus bars
* Dedicated AC surge suppression circuit board
* Dedicated telephone line protection circuit board
* EPCB04000 fuse protecting telephone line circuitry
* Illuminated resettable circuit breaker / power switch
* Dual-orientation wall-mount provisions

The AC outlets are connected using continuous brass bus bars rather than individual wires. Internal wiring between the surge protection circuitry and outlet bus structure is limited, resulting in a relatively simple and compact construction.

The unit was found to be clean internally with no evidence of overheating, carbon tracking, or component failure.

== 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.
