Description
The R4815N1 is a digital rectifier with high efficiency and
power density. It converts 85–300 V AC input voltage to
53.5 V DC output voltage. The output voltage can be
adjusted by the host.
It performs comprehensive protection functions, supports
soft start, and produces low noise. With the latest power
monitoring technology, states of the rectifier and load are
monitored in real time.
Multiple rectifiers can be paralleled.
Key Features
•Input voltage range: 85–300 V AC

Protection
Input overvoltage
protection Protection point: > 300 V AC
Recovery range: 290-300 V AC
Input undervoltage
protection Protection point: < 80 V AC
Recovery range: 70-85 V AC
Output overvoltage
protection 56–60V DC (can be set by monitoring unit)
1. If the overvoltage occurs inside the
rectifier due to a fault, the rectifier
will latch off.
2. If the output voltage is higher than
63 V and lasts for more than 500
ms, the rectifier will latch off.
Output current
limiting protection See Figure 1.
Output short circuit
protection A long term short circuit is allowed. After the fault is rectified, the rectifier
is restored to a healthy state
automatically.
Over-temperature
protection The module protects against overtemperature.

Step 1: Push the locking latch left.
Step 2: Remove the PSU out of the PDU by
externally drawing the handle, as shown
in Figure 5.
Installing the Rectifier
Figure 6 Installing a PSU
Step 1: Push the locking latch left and pull out the
handle.
Step 2: Push the PSU slowly into the subrack
along the guide rail and push the locking
latch right to fix the handle, as shown in
Figure 6.
Transport
The product must be packed with firmly packing
box when transport. Out of the box the mark
“prevent moisture”, “lay down carefully” and other
required mark must have. Any transport tools are
permitted if the product in the packing box. When
transport must avoid rain and snow attack directly
and mechanical shock.
Storage
Product should be packaged in the packing box
before use. The store room should be meet:
-40ºC to +70ºC ambient temperature, related
humidity less than 80%, dry, ventilation and hasn’t
any corrosive gas.
•Only trained and qualified personnel can be allowed to
install or service the rectifier.
•Each rectifier input is protected by two fuses, one for the
live wire and the other for the neutral wire.
CAUTION
•This product should be used in the environment that meets
specifications described in the user manual.
•If the product is used with abnormal power grid input or
exposed to salt mist, dust, or mist, the product may become
faulty, and the resulting product exceptions or component
damage are beyond the warranty scope.
CAUTION

Indicator Color Status Description Measures
Power
indicator Green Steady on The rectifier is supplied with alternating current (AC) input power. The rectifier runs properly, and no measure is required.
Off The rectifier is not supplied with AC input power. Replace the rectifier if the AC input is
normal.
The rectifier is faulty. Replace the rectifier.
Blinking at
0.5 Hz The rectifier is being queried. No measure is required.
Blinking at
4 Hz The rectifier is loading an application program. The rectifier automatically recovers after loading, and no measure is required.
Alarm
indicator
Yellow Off No alarm is generated. The rectifier runs properly, and no
measure is required.
Steady on The rectifier generates a prewarning for power
limiting due to overtemperature.
The rectifier generates an alarm for shutdown due
to ambient overtemperature protection.
Check that the air vent is not blocked
and the ambient temperature is within a
normal range.
The rectifier generates an alarm due to AC input
overvoltage or undervoltage protection. Check that the electrical grid voltage is within a normal range.
The rectifier is hibernated. No measure is required.
Blinking at
0.5 Hz The rectifier communication is interrupted. Replace the rectifier or monitoring module.
Fault
indicator Red Off The rectifier is not faulty. No measure is required.
Steady on The rectifier is locked due to output overvoltage. Pull out the rectifier and reinsert it after
1 minute.
There is no output because the rectifier is faulty. Replace the rectifier.
•The high -voltage power supply energize equipment. Contacting the high-voltage power supply directly or through a
dampened object may cause you to death.
•Improper operations on the high-voltage power supply may cause accidents such as fire or electric shock.
Maintenance
Suggestions
1.Rectify the faults by referring to Table 2.
2.If you cannot rectify the fault according to Table 2, replace the rectifier.
3.Return the faulty rectifier to Huawei for repairing.
