Model 3AS | Energy Harvest Transformers and Harvesting Systems

Models: 3AS Harvesting Current Transformers | 3AST Harvest System (with Output Power Controller)


The Model 3AS Harvest Split-Core Current Transformer and 3AST Harvest System are used to borrow power from electrical conductors (power lines) to provide an output DC that can be used to operate metering instrumentation and charging batteries. The window opening will fit over the power line is 2” ID but other IDs are available. Another lower current range Model 3AS-20-50A provides a regulated VDC output over a small current range, but another version, the 3AST, uses an internal micro-process to control a wider current range input up to 600A or higher. An output connector is available for adding an external cable. The Model 3AS Split Transformer or 3AST Harvest system is either standard or custom made-to-order and can be configured to meet many requirements.
