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.
Power terminals

– Excitation output
Measurement terminals
– 3 phase machine voltage
– 1 phase network voltage
– 1 phase machine current
Analog I/O
– 2 outputs / 3 inputs (configurable)
– +10 V / -10 V references output
Digital I/O
– 4 inputs only (configurable)
– 8 inputs / outputs (configurable)
– 24 V output (600 mA) for external relay
Serial fieldbus
