8 Rectifier
Overview
The rectifier converts ac to dc power for user equipment. This section describes the rectifier features,
functions and alarms.
The QS860A rectifier produces 500W from 90 to 275V
ac
. 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 V
ac
. There is a dead zone of approximately 135 to
150 V
ac
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 V
ac
, and 1635W from 180V to 275 V
ac
. From 85 to
90 V
ac
(low line) and 150 to 180 V
ac
(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 V
ac
to 275 V
ac
. If it is initially powered up from 170 to 265 V
ac
, it will operate as a
1635W rectifier and will shut down for voltages below 150 V
ac
.
The QS864A rectifier produces 2180W from 180 to 275V
ac
. 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 V
ac
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.
