1.2 DY48200-5U-XH01 working principle
The main AC power is input through the two-way three-phase dual power integrated interlocking device (which
can be manually switched), and after connecting to the lightning arrester in parallel, after the power distribution is
carried out through the AC circuit breaker (32A/3P 2-way), it enters the rectifier module for After inversion, output
48V DC to the positive and negative busbars, and then shunt by various types of circuit breakers to supply
various DC loads. The AC input circuit breaker has the functions of breaking control, overload and short circuit
protection for the AC power supply. There are C10A×4 circuit breakers for one power off; C50A×3 circuit
breakers; C63A×2 circuit breakers and 1 circuit breaker for The power-off DC contactor KM1; the circuit breakers
used for secondary power-off are C6A×3; C10A×4; C32A×3; C40A×1 circuit breaker and 1 DC contact for

power-off The device KM2 and the user's battery and load are shunt controlled through three 100A circuit
breakers. Each circuit breaker has corresponding breaking control for the relevant functional shunt equipment
and can provide overload, short circuit and other protection at the same time.
The system has the function of secondary power off. Under normal conditions of the system, various parameters
of the rectifier module and power distribution unit are controlled by the monitoring module, and work according to
their predetermined parameters or user commands. When the mains power fails, the battery starts to supply
power. With the discharge of the battery, the battery terminal voltage begins to drop. When the battery voltage is
lower than 47V±0.5V, the monitoring module reports a DC under-voltage alarm signal; the battery voltage
continues to drop, and a power-off cut off The secondary load is powered, and the first-level cutoff voltage is set
to 44.0V±0.5V. When the battery is powered off for the second time, it will be cut off according to the battery
protection voltage of 43.2V. When the battery voltage is lower than 43.20V±0.5V (adjustable), the monitoring
module will control the action of the contactor KM2 and turn off the important load output. At this time, the power
system will stop. Work. When the external mains power is restored, the system will return to normal working state
at the same time (the above monitoring data are the default values ​ ​
of the system, which can be reset by the
user).
In addition to battery discharge protection, the battery and load over-temperature protection function is only
available in the upgraded version DY48200-5U-XH02 of this product. Generally, it is disabled by default. Users
can activate or disable it by issuing commands as needed, but This temperature control function must be
specially proposed when ordering and specified in the purchase contract.

5.3.6.5 Other parameter settings
The "Parameter Setting" menu provides basic system settings, including language selection, date and time
modification, password management, and software upgrade. If the user needs to use the TCP / IP Ethernet
interface for centralized monitoring, the network parameters such as the IP address, subnet mask, and gateway
IP of the machine can also be set here. For specific operation process and page display, please refer to Figure
5-3-6-12.
Figure 5-3-6-12 Other parameter setting process
By default, the language selection is Simplified Chinese, the baud rate for monitoring and background software
communication is 9.6kbps, the monitoring IP address is 192.168.120.99, and the subnet mask is 255.255.255.0. If
the user is using a network interface, please ignore the network settings, this section does not affect the use.
Users can modify the factory password by changing the password in the menu to improve the security of
monitoring. All passwords can be restored to the factory password through password reset. Under normal
circumstances, do not touch the system reset function. After the system reset, all parameters will be restored to
the factory settings, including the historical alarm will be cleared. The user must set it correctly again before
putting it into use.

5.3.6.6 Sleep parameter setting
The sleep function enables the system to control the rectifier module to be in the sleep or working state according
to the actual load, so that the module is at the optimal efficiency point. The rectifier module periodically turns to
sleep, so that the working time of all modules in the system is balanced. Under the "Sleep Settings" menu, the
user can set certain sleep parameters according to the actual situation of the system, so that the sleep function
can play the best effect. The specific operation process and page display are shown in Figure 5-3-6-13, and the
detailed description of each parameter is described in Table 5-3-6-14.

the system. The control strategy includes the following two methods:
Hibernation mode 1 (applicable in normal mode):
A. Module sleep: When the actual load rate of the module is less than 40%, the monitor turns off the working
modules one by one until the module load rate is greater than 40%. In fact, the minimum number of modules that
are working will be greater than or equal to the "module cardinality" setting
B. Module wake-up: When the system load increases, when the module load rate is greater than the set value of
the upper limit of the module load (default 80%), the monitor will turn on the modules one by one until the module
load rate is less than the set value.
C. Module rotation: If a module is in the sleep state and the sleep time reaches the set value of the sleep period,
the monitor will turn on a module, and turn off the module with the longest working time after the work is stable.
Note: The A, B, and C modes are performed simultaneously. If any of the conditions is met, the system will sleep
or turn on the module.
Hibernation mode 2 (applicable in mixed insertion mode):
For example: the high-efficiency module is 1 # 2 #, and the ordinary is 3 # 4 #.
A. Module sleep: When the actual load rate of the module is less than 40%, the monitor turns off the working
modules one by one until the module load rate is greater than 40%. The monitor preferentially closes the general
effect module, and the closing sequence is 4 #> 3 #> 2 #> 1
#. In fact, the minimum number of modules that are working will be greater than or equal to the "module
cardinality" setting.
B. Module wakeup: When the system load increases, when the module load rate is greater than the set value of
the module's maximum load limit (default 80%), the monitor will turn on the modules one by one until the module
load rate is less than the set value. The monitor gives priority to wake up the efficient module to work, and the
wake-up sequence is 1 #> 2 #> 3 #> 4 #.
C. Module rotation: If a module is in a sleep state and the sleep time reaches the set value of the sleep period,
the monitor will wake up a module and shut down a module after the work is stable. The monitor preferentially
wakes up the high-efficiency module (if any) and then shuts down the general-effect module (if any) first.
