ABB UNITROL® 1020 Compact and powerful Automatic voltage regulators

ABB UNITROL® 1020 Compact and powerful Automatic voltage regulators

DESCRIPTION

UNITROL 1020 and UNITROL 1010 are the latest products  of the UNITROL 1000 family. For most reliable operation,  the communication and control tasks are split in 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 1020 and UNITROL 1010 are designed for a wide  range of ambient temperature and harsh environmental  conditions and can be mounted directly on the machine.

INTRODUCTION

Polymer housing

Protects all live parts to  prevent electric shocks.

USB port

– Connects the CMT1000 (commissioning and  maintenance tool) 

– Device configuration and  event and data upload  without any other power  supply

Indication LEDs

– Green: Power ON,  blinking indicates software  is running 

– Yellow: Excitation ON,  blinking indicates limiter is active 

– Red: Alarm, blinking  indicates start up error

Ethernet port

– Connects the CMT1000 

– Remote access over  Modbus TCP

Solid aluminium base plate

– Robust mechanical design  allows use in high vibration  applications.  

– Can be mounted directly  within the machine  terminal box.

Power and measurement  terminals

– Specified up to 30 A  continuous current and  max. cable up to 4 mm2  (AWG 24–10) 

– Tension spring terminals  for reliable connection 

– Easy access over test  points

Local human interface

– Intuitive local control panel  for indication of AVR  status, active limiters  and measurements 

– Local control can be taken  over to change parameters

The UNITROL 1000 family has freely configurable  measurement and analog or digital I/Os. The configuration  is done via the local human-machine interface or CMT1000  software.
