Signal name Pin number Signal definition
Ac input 1 Input terminal of the AC power supply of a phase module of the three-phase power supply. The input mode is three-phase three-wire system, and no phase sequence requirement is required
2 One phase of three phase electricity
3 One phase of three phase electricity
4 Protective ground The protective ground outlet of the PE module is connected to the module shell
Communication port 11 485A weak signal end, the communication interface between the module and the upper device is in serial asynchronous transmission mode, and the interface level is RS485
13 485B
Current sharing interface 17 Current sharing + weak signal end. When two or more modules output in parallel, this end needs to be connected in parallel to realize load sharing of modules; Suggestion: Use shielded cables for equalizing currents between layers
19 Current equalization - DC output
27 Output + GF11040 is: 26 and 27 Pin: Output +
Pins 28 and 29 are output -
28 Output -
Note:
1. In order to ensure safety, please ensure that the PE end of the protection ground in AC input is correctly connected to the ground;
2. To ensure system reliability, the three-phase AC input of each module must be configured with a separate incoming circuit breaker.
