General Description

Access Power Rectifiers

Two types of fan-cooled, hot-pluggable Access Power Rectifiers are available.

•APU48 – 48 V, 720 W, (120 - 240 V AC)

•APR48 – 48 V, 1500 W, (208 - 240 V AC)

There are three status indicator LEDs on the Access Power Rectifier front panel (Power On, Urgent Alarm and Non-Urgent Alarm).

Details about replacing a rectifier can be found in Chapter 7.

"Power On LED (Green) – indicates that the rectifier is powered.

#Non-Urgent Alarm LED (Yellow) – indicates non-critical conditions, such as:

•Rectifier in power/current limit mode

(This normally happens for a short period of time when the batteries are recharging.)

•Rectifier operating in temperature turndown mode, because of high ambient temperature or low AC supply voltage

$Urgent Alarm LED (Red) – indicates critical fault conditions, that require urgent attention, such as:

•Rectifier failed

•Rectifier shut down

•AC supply failed (green LED off)

•Very high AC supply voltage

•DC overvoltage
