EPS30-4815AF Power System The AC-powered cabinet uses the EPS30-4815AF power system to convert the AC input into the DC power for power distribution. Function The EPS30-4815AF power system converts one AC input into two DC outputs to implement the DC power distribution. It can be connected to one set of batteries and use its monitoring module to manage the batteries. The EPS30-4815AF power system can also use the external sensor transfer box to collect and report the status of sensors and standby detected parameters. NOTE: The rectifier modules of the EPS30-4815AF power system work in the load balancing and mutual hot backup mode. Appearance Figure 4-1 shows the appearance of the EPS30-4815AF power system.
