Chapter 2 - System Overview
2.1 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.
2.2 Design Principals
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.

When the load requires a large inrush current and exceeds the
maximum current supplied by the power supply, the power supply will
be protected and turned off by itself. Then the load current is
completely provided by the battery. When the load current is less
than the maximum current supplied by the power supply, the power
supply automatically starts working.

4.3 Mains Power Supply Connection
A power supply to the VP-1405A can be in two options which should
be selected one of them during ordering the component.
The power supply input of VP-1405A is a universal AC / DC voltage
with range 165~265VAC, 40~60Hz, and 200~375VDC. This should
be connecting to the field mains power via 4A/250VAC fuse to
protection.
Extensive filtering with transient protection is built into the V4-1405A
to ensure reliable operation. Transient energy must be suppressed
and conducted back to the source through filter ground terminal PE
and also FG screw pins on the chassis.
