Digital Equipment Corporation H7318-AJ Power Conditioning System Plus.

The PCS+ provides voltage regulation, power conditioning and distribution of AC power for small to medium-sized computer systems.  It can be configured to monitor and display both internal and external failure or status information.  Includes lighted indicators as well as an LCD display to show status of the unit.  It can also be connected to a standard terminal to display the contents of the display.  Also includes a 40 column printer to produce hard copy of alarm conditions or probe status.  Unit contains logic circuits to monitor up to 43 internal and 69 external probe sensors.

When a failure occurs the unit can be programmed to generate an alarm, energize one or more of three logical relays, or cause an emergency shutdown of the system.  There is a front panel bypass switch.

The PCS+ has input circuit breakers, filtering, voltage regulation and output distribution facilities.  This consists of transient overvoltage protection and over current protection via circuit breakers. 

Each phase of the input is regulated separately by automatic selection of the input taps in the isolation transformer.  Tap selection is accomplished by the control logic modules which sense line voltage changes and select SCR driver modules which select transformer taps.  There are seven taps for each input phase leg to adjust voltage.

Removed from service. Comes with full installation instructions, programming and operating manual.

(PS) 153-3A-136

Elgar uninterruptable power supply. In it's day, delivered 41.6 amps of current for up to 8 hours. Includes static by pass switch.

This UPS is designed to be on-line 100% of the time, supplying all system power. In this mode, there is no switch over time because you are on-line. This is the preferred mode, but power consumption is slightly higher than running on standby (i.e. 0.68 amps input, 41 amps output). Optionally, it can be run in switch mode and come on-line quickly in the event of a brown/black out.

• Input: 120 / 208v, 3 phase @ 68 amps
• Output: 120 / 208v, 3 phase @ 41.6 amps max
• Dimensions: The main cabinet is 76.5" high x
55" wide x 19" deep
• Weight: 2,250 lbs
This system was removed from service in working condition in 1997. Included is a "load" for testing off line. This consists of an electric furnace on casters, with a cord that plugs directly into UPS. Also included are spare parts and manuals. Shipping, moving, crating etc... is the responsibility of purchaser. Batteries are no longer part of this system.
