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
% Retaining Screw (loosen to remove rectifier)
