What is the difference between 3P+1 and 3P+N?
Feb 20 , 2025
The SPD combination modes include nP, nP+N, and nP+1. 3P+1 mode is used to raise the voltage (for example, the JLSP-GA750/100/3P+1 in the photovoltaic series is used to raise the voltage).The N in 3P+N refers to the addition of a gas discharge tube (under the action of this electric field, the gas inside the gas discharge tube begins to be ionized. When the external voltage increases to ...
