System Overview

In places that need reliable power supply and also backup power via

battery is important and is an important issue for any engineer or

consultant or user, the unique design charger of the VP-1405A from

V-PM1000 Product Series of Veesta World Company along with its

quality construction will be a complete and convincing answer for

everyone.

In this chapter you will found how this product has been designed

and how it can help you.

The VP-1405A can work after inputting AC power. The power supply

will power the load, and at the same time, the battery is charged by

constant current and constant voltage (CC/CV mode). When the

battery is finished charging, the power supply automatically switches

to the floating state. Meanwhile the power supply provides floating

charging voltage and current to supplement the normal self-

discharge of the battery.

When the AC is powered off, the battery is continuously providing the

power to the load in zero switching time. When the battery is

discharged to the under-voltage alarm point, the battery under-

voltage warning signal is on. When the battery discharge is lower

than the under-voltage protection point, the power is automatically

turned off. These points are programmable and also can be set

Modbus RTU. We do not recommend changing values of these

points.

If it is need to turn off the battery output in advance, it can be done

manually by press the battery OFF button for 5 seconds or remotely

control the relay controlled by the CPU to short-circuit the battery

remote control terminal or also by remote Modbus RTU command,

then the battery will be shut down in advance.

Note: The battery early exit function is forbidden when the battery is

activated; otherwise the load will be powered off for a short time.

When the battery exits early and the load is cut off, the power can be

restored only manually or when the AC is restored.
