Eco:

The ECO version covers essential functionality

for cost sensitive applications.

Light:

The light version adds to ECO standard

functions as rotating diode monitoring and

remote control via modbus. Furthermore, a

simplified data logger called history logger

allows the user to track the last two hours of

operation for analyzing.

Basic:

The BASIC version is the ideal solution for

applications with multiple machine operating

on the same busbar. Accurate reactive load

sharing via serial communication (VDC) and

fast automatic synchronization are the key

functionalities. Furthermore, a dual-channel

functionality and motor start sequence

functionality are supported.

Full:

Complex and demanding projects often ask for

transient recorders and plant clock synchronized

data logger function.

The FULL version has the capacity to meet these requirements.

UNITROL® 1005. UNITROL® 1010 and

UNITROL® 1020 are the latest products of

the UNITROL® 1000 family. For most reliable

operation, the communication and control

tasks are split into separate controllers.

The non-volatile flash memory of the AVR stores

events and data logs to enable fault analysis and

fast trouble shooting. Time synchronization is

done over Ethernet communication, and the

events and data logs are time-stamped.

UNITROL® 1000 is provided with modern

communication ports like Ethernet and USB for

connection of the PC-based commissioning tool CMT 1000.

Besides it is possible to power up the controller

of the device via USB port. Thus the user can

download files or configure the device even when

no input power is available. The AVR output stage

is based on proven IGBT technology, which allows

AC and/or DC voltage inputs from different

sources. UNITROL® 1005. UNITROL® 1010 and

UNITROL® 1020 are designed for a wide range

of ambient temperature and harsh environmental conditions.

Single or dual channel controllers: the main benefit of a dual channel system is its lower failure rate.

The changeover from one channel to the second channel is done automatically and bumplessly thanks to

UNITROL 1000 technology.

This guarantees higher availability of the overall system. It also allows you to stay online if one of the 

channels fails. While a single channel failure would cause a trip of the system,

the dual channel controller allows you to find root cause and fix issue whilst the system stays running.

Full redundancy: in dual channel applications both the channels have independent power supply and

allow to be fully redundant in the operation.

Gride code compliant product:

• Many aging units require to be updated to newer standards.

• When PSS is required by the Grid Authority, UNITROL 1000 has the integrated PSS as an option for both

systems and devices. 

Meaning you are not required to use any additional device to ensure compliancy with the requirements.

• The UNITROL 1000 FLEX System is supporting an alternative excitation power supply which will keep the

synchronous generator online in case of a network fault.

Premounted and tested systems: all systems are already mounted, wired and tested when leaving our

factory.

The systems can be mounted into existing or new cabinets easily. This reduce the engineering and

commissioning time, but still offers later configuration on-site by simple configuration and editable

documentation.

Programmable protection thresholds

Programmable thresholds allow you to protect the

capacitor bank against over- and under-voltage, over

temperature and excessive harmonic distortions.

Network information and capacitor bank monitoring

The RVT computes and displays network and capacitor

bank information such as voltage, current, harmonics

spectra and much more.

Multi-language support

The RVT allows you to choose its working language

between English, French, German, Spanish and Chinese.

High ambient temperature rating

The RVT is suitable for harsh ambient environments thanks to

its maximum ambient temperature rating of 70°C.

Multi-voltage and multi-frequency

The RVT may be connected to network voltages in the range

100-460Vac, 50/60Hz. RVT’s measurement voltage is up to

690Vac without connecting any additional PT.

Works with 5A and 1A CT’s

Both 5A and 1A CT’s may be connected to the RVT.

Digital inputs

Two digital inputs can be used for day/night power factor and

external alarm respectively.

Two alarm relay outputs and fan / warning output

RVT has two alarm relay outputs (NO and NC) and a FAN/

Warning relay output.

Other powerful features

RVT is also a MV and HV bank controller

By connecting a PT to the RVT voltage measurements inputs,

and setting the proper [V scaling] according to the PT ratio,

the RVT is able to control a MV or HV capacitor bank just like

a LV capacitor bank.

Easy commissioning

The fully automatic set-up of the RVT parameters totally eases

the bank commissioning process.

Menu navigation

The clever organization of menus and sub-menus ensures

menu navigation easy and intuitive.

Guided navigation and programming

Online help information guides you step by step in the menu

navigation and RVT programming.

Communication

RVT has versatile communication interfaces: in addition to

Ethernet 10/100BASE-T and USB2.0. the RVT supports

RS485 connection as well. All parameters settings and

measurements are accessible remotely.

Fully automatic set-up

C/k (sensitivity), active outputs, switching sequence and

phase shift can be automatically set-up.

Touch Screen

3.5 inch colorful QVGA touch screen eases your parameter

settings.

Ethernet connection

With ABB PQ Link software, you may easily plug an RJ

45 to RVT and communicate with the controller through a

10/100BASE-T interface anywhere in the world.

USB connection

RVT supports USB2.0 connection; which makes it possible to

connect to a computer via a widely used USB cable to access

all RVT parameters.

Up to 8 Temperature alarm outputs

RVT can monitor 8 hot spots in your bank through eight

daisy-chain connected temperature probes.

Real time clock

RVT real time clock tracks and logs date and moment of each

alarm and event.

Hardware and software lock

Both hardware and software locks are equipped in the RVT

for bank setting protections from any unauthorized access.

Distinct features

Power factor correction for both balanced and unbalanced loads

In modern day installations, unbalanced loads are increasingly

common, especially in residential or commercial buildings.

RVT addresses your power factor issues from both single

phase loads (L-L or L-N) and three phase balanced/

unbalanced loads. RVT is capable of compensation to

each phase individually or compensation to three phases

globally. Another distinct feature of RVT is individual phase

measurements and energy calculations.
