Emerson 731 Series 48V600A/R48-3000E3 power supply

Load power-off and battery low voltage protection

When the AC power is off and the rectifier module has no DC output, the battery starts to discharge. Set when voltage drops to undervoltage

When the fixed point is 45.0V (adjustable), the system will issue sound and light alarm. When the battery voltage continues to drop below the load

When the electric operating point is 44.0V (adjustable), the load power off contactor is disconnected and connected to the load power off branch

General communication loads (such as local switches) will be cut off from the power supply, and critical loads (such as transmission devices)

Standby) power supply can thus be extended. As the battery discharge process continues, if the battery discharge to termination

Voltage battery protection action point 43.2V (adjustable), the battery protection contactor will be disconnected, the battery discharge process will be terminated, and the power supply of all communication loads will be suspended, so as to avoid battery damage due to overdischarge. When an AC call comes in and the rectifier module outputs a normal DC voltage, the load is powered off and the battery contactor automatically closes, and the system returns to normal operation.

Functions such as load power-off and battery low voltage protection can be manually controlled.

Fault alarm and protection

Net Sure731 48V600A power supply system with complete fault warning and protection. The monitoring module can collect system data in real time, and detect the status of load output fuse, battery fuse, and II/C level surge protection device. You can flexibly set alarm levels for system faults, such as AC input overvoltage or undervoltage, DC output overvoltage or undervoltage, and module faults. You can also flexibly configure alarm types indicated by alarm dry nodes.
