4 Rectifiers

NE100AC24ATEZ

Overview
The NE100AC24ATEZ Series rectifier (100A) operates from single-phase ac service with a
phase-to-phase voltage within the range of 95-275Vac.
The rectifiers are shipped separately from the cabinets for quick and straightforward installation into
rectifier shelves at the site. Interconnections to ac input, dc output, and control signals occur
automatically during insertion. No settings or adjustments to potentiometers are necessary.
The NE100AC24ATEZ rectifiers are UL Recognized for both the U. S. and Canada, comply with UL1950
(Information Technology Equipment), and meet EN60950 requirements.
Front Panel Display
Status Indicators
Three LEDs on the rectifier's faceplate indicate the rectifier's condition.
• The Norm LED is green and is lit when the rectifier has AC input present and is working properly.
• The ACF LED is amber and is lit when there is no AC input present to the rectifier.
• The Fail LED is red and is lit if there is a failure in the rectifier.
Lamp Test
To test the LEDs on the rectifier front panel, press the Lamp Test button on the controller.
Features
Output Current "Walk-in"
This circuit controls the time (up to eight seconds) required for the rectifier to reach normal operating
conditions after it is turned on. This feature minimizes the starting surge on the customer's power
source.
Output Protection
Rectifier is equipped with an internal fuse for plant protection if a fault occurs in a rectifier.
Electronic Current Limit
When the output current tends to increase above the current limit set point, the current limit circuit
overrides the voltage regulating signal and safely limits the output current of the rectifier, thus
preventing damage to itself or the load.
