Graigar Smartgen HSM300 Synchronous Module for Genset Automatic Parallel Voltage Testers Build-in high precision 200MHz BWBrand: Graigar Color: Black&green Features: HSM300 Synchronous Module is special design for genset automatic parallel. On the basis of the parameters, the module automatically tests the conditions of paralleling (pressure difference, frequency difference and phase) and send parallel signal when the conditions meet parallel requirements. HSM300 Synchronous Module is used for the occasions that gens synchronize to bus. The module is brief to operate,
