This well-known range - especially in the marine world -includes models for just about every possible requirement: from low-cost 6 A units to 100 A chargers for the most demanding situations.
All models are designed by Charles Sterling who has written detailed information on theory features, their applications and their comparative performance.
Sterling's range of chargers is made up of four types:
Pro Budget - A range of low-cost, compact, multi-stage chargers from 6 to 20 A (12 V) and 7 to 12 A (24 V)
International - High-quality, 3-output, 4-stage chargers from 10 to 20 A (12 V) and 15 A (24 V)
Pro-Digital- Digital, 3-output, 4-stage chargers from 30 to 50 A (12 V) and 25 A (24 V)
High Power Pro-Digital - Digital, 4-output, 4-stage chargers from 80 to 100 A (12 V) and 50 A (24 V)
