1.3 PRELIMINARY RECOMMENDATIONS
The following are some preliminary recommendations, which should be read before starting
the product installation and operation procedures.
DANGER!
Failure to comply with the safety instructions may result in risk of death and/or
damage to the equipment. The product has its own power source (batteries).
Therefore, the output connections and/or terminals may be energized even if the
input power is not available or connected to the equipment. This equipment has
potentially hazardous voltages.
DANGER!
Do not block or insert objects into the ventilation fins. Never cover the equipment
with other materials or objects, as it may cause overheating and risk of fire. All
repairs and maintenance jobs must be performed with the equipment completely
de-energized and only by technicians of the WEG Authorized Technical Assistants.
DANGER!
Always disconnect all power sources (main and battery) before touching any
electrical parts connected to the equipment.
Many components may remain charged with high voltages and/or moving (fans)
even after the battery has been disconnected.
Wait for at least 10 minutes to ensure the full discharge of the capacitors.
DANGER!
Batteries must be recycled. Never dispose of batteries by means of incinerators,
crushers, trash compactors, ordinary trash cans or by throwing them directly
into the environment. There are risks of explosion or fire when they are exposed
to flame, subjected to pressure or come into contact with energy-carrying
materials (metals or liquids), in addition to contaminating the environment due to
the materials part of their composition.
DANGER!
When in operation, electric energy systems, such as transformers, converters,
motors and cables, generate electromagnetic fields (EMF). Therefore, there is
risk for people with pacemakers or implants who stay near those systems. Thus,
such people must stay at least 2 meters away from this kind of equipment.
ATTENTION!
In order to reduce the risk of fire and electric shock, install the product indoors in
an environment with controlled humidity and temperature, free of pollutants and
explosive agents, not exposed to direct sunlight. Do not install the product in a
place where the temperature and humidity are out of the technical specifications
indicated in Chapter 7 TECHNICAL DATA on page 7-1.

3 PRODUCT DESCRIPTION
3.1 INTRODUCTION
The line of Digital Three-phase Rectifiers RTDW has double energy conversion and full digital
control. Those innovations add to the RTDW significant improvement in performance, efficiency,
operation and reliability in comparison to conventional rectifiers.
3.2 GENERAL CHARACTERISTICS
3.2.1 Output Types
The RTDW can operate with three types of output converters: DCU, DDU or Direct. By default,
the system used is the DCU, allows a more precise and effective control of the consumer voltage.
3.2.1.1 DCU Converter (Default Configuration)
The DCU system is based on the use of a DC/DC converter to regulate the output voltage. This
configuration allows a precise and stable regulation of the consumer voltage.
3.2.1.2 DDU Outputs (Optional Configuration)
It uses diodes in series with the output, divided and controlled by up to four stages to ensure
that the voltage remain within the specified minimum and maximum limits.
3.2.1.3 Direct Output (Optional Configuration)
In this model, the rectifier output is directly connected to the consumer, and the output voltage
will be the same as the battery voltage, according to charge, recharge and discharge variations.
3.2.2 System Components
The RTDW system is sturdy and highly reliable, consisting basically of three blocks: Thyristor
rectifier, the external battery bank and the output block. The output block vary according to
constumer's choice and can be the following: DCU - Drop Converting Unit, DDU - Drop Diode
Unit or Direct Output. The Figure 3.1 on page 3-2, Figure 3.2 on page 3-2 and Figure 3.3 on
page 3-3 present the rectifier schematic when using DCU, UDC and direct output, respectively.
3.2.3 Operation
In Normal mode (AC power supply present), the first converter (rectifier) supplies energy to
charge/maintain the battery bank and simultaneously supplies energy to the converting unit
DCU, DDU or directly to power the consumer, according to the project. If the AC power supply
fails, the consumer starts receiving uninterrupted power from the batteries. When the AC
power supply is restored, the rectifier returns to normal operation, charging the battery bank
if necessary and feeding the rest of the system. In case of an AC power supply outage for a
long time, the battery discharges to a minimum voltage limit; at this moment, the LVD process
begins, explained in Section 6.4 LVD - DISCONNECTION DUE TO LOW BATTERY VOLTAGE on
page 6-9. In models without the LVD function and with Direct Output or DDU, the consumer
will continue discharging the batteries until the AC power supply is restored. Figure 3.1 on page
3-2, Figure 3.2 on page 3-2 and Figure 3.3 on page 3-3 show the operation of the rectifier
when using DCU, DDU, and direct output respectively.

Product Description
3-2 | RTDW
The digital rectifier has a dedicated circuit that detects occasional leakage currents from the
equipment positive and negative terminals or from the loads to the earth, generating events
and alarms in case of fault.
Note: This circuit is disabled in RTDW models that have positive or negative terminals grounded.
The RTDW has electronics with dual power supply and a supervisory system that operate
redundantly, providing even greater protection to the consumer's power supply in case of failure.

3.2.4 Output Parallelism
By default, the RTDW with DCU output has an internal parallelism diode that allows connecting
the consumer outputs of two or more rectifiers, so that all of them can supply the load.
If it is desirable to determine how each rectifier will operate: taking full load or remaining in
standby, it is possible to adjust the output voltage of the individual DCU in each RTDW. To do
that, it is necessary to maintain a voltage difference greater than three volts in relation to the
other rectifiers in parallel. The RTDW with the highest voltage will take all the load connected
to the bus and the others will remain in standby.
If this rectifier with a higher voltage presents a deviation that compromises the correct control
of the output voltage, the other rectifiers will automatically supply the load.
ATTENTION!
Models with DDU or Direct Output can only operate in parallelism if the project
includes the parallelism diode in its output. In these two output models, it is
not possible to determine which of the RTDW will take charge. This will occur
according to the variation of the output voltage and the dynamics between them.
