1. Summary
DTSD51Z/DTSD51ZF Three Phase Static Carrier Wave Multi-function
Energy Meter is designed with large-scale integrated circuit (LSI).
Its advantages are simple structure, high reliability, less power
and long lifetime etc. Auto meter reading and control can be
achieved with PLC channel and software technology.
