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

• Operating temperature range: –40ºC to +75ºC

• Total harmonic distortion (THD): ≤ 3.5％

• Digital control mode

• Hot swap

• Supports intelligent electric meter

• Supports CAN communication

• Supports LED display

• Supports voltage adjustment,current

adjustment,and current sharing

• Meet Rohs requirement

• Passes the TUV, CE, UL certifications and gets

the CB certifIcate.

• Disconnect above 320 V AC

Note: If the altitude is within the range of 3000 m to 4000 m, the maximum operating

temperature decreases by 1°C (1.8°F ) as the altitude increases by 200 m.

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.
