Analogue AVR with digital control: The AVR R250 generator combines analogue and digital control functions, and uses a microcontroller and transistor to regulate the power for accurate control. Durable design and reliable performance: R250 is built with electronic components designed for durability and reliable operation under different conditions. It has a rated residual current of 5 A and a maximum residual current of 7 A. Designed for optical equipment with excitation control: The AVR R250 is specially designed for optical machines with excitation that can control the current to maintain stable output voltages. It provides voltage regulation, easy adjustment, and reliable use. Flexible AVR control options: The AVR control features include a potentiometer for voltage and stability adjustment, a frequency selection option, and a remote voltage adjustment option. Use case: Optical laboratory power supply for precision equipment: Powers laser modules and other optical components where stable voltage is critical to performance and measurement accuracy. Use case: Field service and remote installations: Remote voltage adjustment capability allows onsite tuning to match loading conditions without direct access to the equipment. Use case: Industrial equipment with excitation demands: Supports excitationdriven loads that require tight voltage regulation across varying operating conditions, improving process control and equipment longevity.
