GF1115P PROGRAMMABLE AC LOAD UNIT

GF1115P three phase programmable AC load unit is mainly used as the load for on-site verification of electric vehicle AC charging pile. The on-site detection process of AC charging pile can be realized by cooperating with our GF1115 AC charging pile on-site test set. The whole detection process meets the requirements of relevant national detection standards and measurement standards JJG 1148-2018 verification regulation of electric vehicle AC charging pile.

The internal motherboard of the resistance load box adopts the processor chip of armcortex-m4 core architecture, which automates the workflow of the whole resistance load box, reduces manual participation and saves operation time. The internal structure adopts multi-channel high-power resistance parallel connection, which is connected through high-quality relay control. Multiple gear switching can be realized through the control relay. The whole process is fully automated without manual participation. Forced air cooling is adopted, and the circuit structure is simple without too much maintenance, saving the heat dissipation cost. Internal temperature detection is set to monitor the working temperature in the box in real time, ensuring the safety and reliability of the load in use. Two national standard AC charging gun sockets are installed on the box to facilitate user cascade and increase load power.
