Three Phase Testing Bench (SP-5505P)

1. Introduction
SP-5505P three phase portable test equipment is designed for energy meter Research and Develop department or energy meter Repair department. It uses the small phantom load power source SP-5505P and high precision three phase reference meter. The small cubage let it can be put on a table and can be moved easily.
1.1 Feature and function
1)SP-5505P three phase phantom load power source is a high stability and high efficiency phantom load power source.
2) External high precision three phase reference meter. User can use the high precision three phase reference meter individually.
3)Test equipment equipped with RS-232C communication port, can be operated from software.
