1.2.3 Metering Features
The VP-1405A provide the metering of output load current, voltage
and also the battery load and voltage in good accuracy which whelp
users to maintain the operation of their system load and also the
battery life. This information is available via the ModbusRTU protocol
by RS485 communication network.
 Output load Voltage metering

Output load Current metering

Battery Voltage metering
 Battery Current metering

Battery Charge/Discharge metering
A keyboard and light contrast LED display also provided to do some
urgent case operation or status monitoring.
1.2.4 Setting and Set-points
In VP-1405A there is a feature that you can provide some settings
regarding the change default configuration or apply new setting for
operation as like as any of the assignable output relays may be used
to trigger and alarm for specific applications and status.
You can also assign and change some threshold like alarm of under
voltage or change of shutdown output load regarding the current
situation of battery voltage and etc.
1.2.5 Communications
Integrate process, instrumentation and electrical requirements in a
plant automation system by connecting VP-1405A power system
together to a DCS or SCADA system. A PC running the VP-1405A
can change system set-points, monitor values, status and alarms.
Continuous monitoring minimizes process downtime by immediately
identifying potential problems due to faults or changes from growth.
