Question:
What is the difference between ordinary secondary access and W ( type external transformer )?
Answer:General secondary access to the built - in transformer . The transformer is selected according to the actual current on site . Model W comes with external transformer ( can not be disassembled , otherwise it will burn the meter ). The transformer has been installed on site for easy wiring and free of disassembly .
