About This Product
The Ranger is meant for general-purpose student use where a continuously variable supply is needed and the maximum voltage should be lockable. The ac and dc outputs can be drawn at once if their combined current stays within 8.5A. A resettable electronic trip, a thermal transformer trip and a slow-blow fuse protect the unit, and a quiet internal fan keeps it cool. The Ranger Power Unit is available for supply within India and for export to Cameroon, Guinea, Cambodia, Mexico, Kazakhstan and Liberia.
Frequently Asked Questions
Q1. What is the advantage of a continuously variable supply? The output can be set to any voltage up to 15V rather than fixed steps, while the key lock still caps the highest voltage students can reach.
