Professional technical help always within your reach:ABB’s global excitation service network.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 conditionshttps://www.weikunfadacai1.com/
UNITROL® 1010 and UNITROL® 1020
UNITROL® 1020 combines high performance control and power circuits with a simple mechanical design. The construction provides a platform for a broad range of applications, including those in highly demanding environmental conditions. Furthermore, high levels of EMC immunity is achieved through separation of the power and measurement terminals from the I/O connectors.
