UNITROL 1010 is a powerful and compact automatic voltage regulator with built-in dual channel support, advanced load sharing between machines operating in parallel, rotating diode monitoring, automatic synchronizing and several integrated communication options.
UNITROL 1010 is the voltage regulator of the UNITROL 1000 family intended for small and medium synchronous generators and industrial machines. This voltage regulator is manufactured using the most advanced microprocessor technology and IGBT semiconductors allowing current output up to 20 ADC for continuous operation. UNITROL 1010 provides high performance in a wide range of temperature and vibration conditions and it is fully certified according DNV and UL standards. UNITROL 1010 has additional features in contrast with legacy versions, as for instance Ethernet, USB, data and event logger and many others.
UNITROL 1010 is a compact device with limited functionality and is designed for excitation currents up to 10 A nominal. It supports the same interfaces and has the same mechanical footprint as UNITROL 1020.
