8 Rectifier
Overview
The rectifier converts ac to dc power for user equipment. This section describes the rectifier
features, functions and alarms.
Figure 8-1: QS86x Series Rectifier
The QS860A rectifier produces 500W from 90 to 275Vac. There is a dead zone of
approximately 135 to 150Vac between the low line and high line ac input conditions where
the rectifier shuts down. However the rectifier automatically restarts operation once the ac
input voltage is out of the dead zone. It has two built-in fans and operates from -40 to +75°C
ambient temperature.
The QS861A rectifier produces 817W from 90 to 275 Vac. There is a dead zone of
approximately 135 to 150 Vac between the low line and high line ac input conditions where
the rectifier shuts down. However, the rectifier automatically restarts operation once the ac
input voltage is out of the dead zone. It has two built-in fans and operates from -40 to +75°C
ambient temperature.
The QS862A rectifier produces 1363W from 90V to 132 Vac, and 1635W from 180V to 275
Vac. From 85 to 90 Vac (low line) and 150 to 180 Vac (high line) it goes into limited power
mode where it continues to perform at a reduced output power level. It has two built-in fans
and operates from -40 to 75°C ambient temperature. If it is initially powered up from 90V to
132V, it will operate as a 1363W rectifier and operate from 90 Vac to 275 Vac. If it is
initially powered up from 170 to 265 Vac, it will operate as a 1635W rectifier and will shut
down for voltages below 150 Vac.
The QS864A rectifier produces 2180W from 180 to 275Vac. From 150 to 180V it goes into a
power limited mode where it continues to perform at a reduced power level. It has two built-
in fans and operates from -40 to +75°C ambient temperature
The QS865A rectifier produces 2725W from 180 to 275V . From 150 to 180 Vac it goes into
power limited mode where it continues to perform at a reduced output power level. It has two
built-in fans and operates from -40 to 65°C ambient temperature.
