Capacitive Load Unit EM-30-07-03 (300VAR)

Description

This series of capacitive Loads is designed to be used with all AC/DC Generators, Machines and Three Phase Transformer in a training environment. For this purpose the units are enclosed in metal housings and provided with Educational Terminal Boards with 4 mm safety terminals socket and clear synoptic showing the feasible connections. The units are also provided with a reference manual which illustrates their use and typical experiments.
