Chapter2 Product Introduction
2.1 SystemApplication
Intelligent switching equipment is usually connected between grid, PCS and load at the same time, used to dispatch the
power configuration between the three, grid can be composed of low-voltage distribution network or a small range of oil
machine power supply network, the load is local load for industrial and commercial use, when there is a fault in the grid, it can
be switched off the grid through PCS to realize grid and load switching, when PCS has a fault, cut off the connection between
grid and PCS to ensure normal operation of the load.

2.4 Function Description
The functions of the PWD-100M intelligent switching box can be basically summarized as follows.
On-grid active cut off-grid: When PCS module PWS2-(29M,30M)-EXwith PWD-100M intelligent switching box
systemworks in the on-grid state, if the user takes the initiative to set off-grid, the system switches off-grid operation, at which
time the load is carried by PCS alone.
Off-grid active cut to grid: When PCS module PWS2-(29M,30M)-EX modulewith PWD-100M intelligent switching box
systemis working in the grid-connected state, if the user actively set the grid-connected, the system switches to
grid-connected operation, and the load is driven by PCS and the grid together at this time.
When the PCS module PWS2-(29M,30M)-EX module with PWD-100M intelligentswitching box system is workingin
grid-connected state, if abnormal condition of the grid is detected, the system will automatically switch to off-grid operation,

and the load will be driven by PCS alone; if the grid is back to normal, the system will automatically return to grid-connected
operation, and the load will be driven by PCS and the grid together.
Data storage: PWD-100M intelligent switching box stores operation information, operation records, fault records and
other information.
Communication function.
⚫The standard RS485 interface can be connected with EMS and other monitoring equipment.
⚫The standard Ethernet interface is used to communicate with the host computer to achieve remote control,
remote software upgrade and other functions.
⚫Standard CAN interface can be used for parallel communication with PWS2-(29M,30M)-EX.
Protection functions.
⚫Overcurrent protection
⚫Overload protection
⚫Short circuit protection
⚫Simultaneous failure protection
⚫Environmental over-temperature protection
⚫Grid voltage monitoring
⚫Grid frequency monitoring
⚫Anti-islanding protection
⚫Redundant protection functions in accordance with VDE certification
