Question 20: Can it accept different specification of rectifier module in one rectifier system>
Answer :
No
Once system accept one specification of rectifier module
Question 21 : what is the outstanding character with the rectifier module ?
Answer :
High temperature resistant
When temperature get to 55 ℃, it still with maximum power output and without temperature protection.
When temperature get to 55 ℃ ~ 65 ℃, the rate power output would reduce in automatic
It can keep 80% efficiency when the working environment under 65℃ and with 176~280 Vac Input
Question 22 : what is the main function of monitor module ?
Answer :
Item Remark
Remote monitoring of the host The host can conduct the remote message, remote sense and remote control.

Question 25: When the power supply system fails, how should we do?
Answer:
First, we should identify the reasons distinguish the load or power supply system, a host or a battery pack. Although the switching power supply system host has failed self-test function, but it does not point directly opposite, very convenient for replacement parts, but we have still to repair the fault point, still need to do a lot of analysis, detection work;
Also as part of the self-test fails, the fault display of the content may be wrong;
The host appears breakdown, insurance or burned off device fault, we must identify the reasons and to reboot after troubleshooting, otherwise the same spate of failure;
Even the best equipment there lifetime, there will be various types of failures, but maintenance work is done properly can extend the life and reduce the occurrence of failure, not because of high intelligence, maintenance and neglect of the maintenance work to be undertaken to prevent. It is an important guarantee for safe operation at any time.
Question 26: What is the methods of the rectifier system parallel operation use ?
Answer:
The first program (recommended):
1. First we sets a DC power source directly and machine capacity is also not limited, with only a monitor control rectifier operation, another monitor for the backup.
2. The monitor can be manually backup or automatic backup, switching power supply products because we have an indication of monitor monitor normal relay, may indicate a fault with the monitor manual backup automatic backup realize it is also more convenient.
3. The key point of this program is the exchange of loop-powered two systems must be independent circuit. Because the primary factor leading to the collapse of the entire system is AC-powered operation of the mine or overvoltage surges;
4. The use of two separate AC circuit power supply can greatly reduce the probability of the whole system crashes. DC converter can be solved and the machine after all flow, battery charging current limiting.
The second scheme: DC and machine monitor hot backup
The first scheme is basically the same, except that the monitor must SC200, SC200 use the monitor standby feature, due to the higher cost of using SC200, but it can be regarded as perfect and advanced machine. Line of Control between the two systems is also less and neat.
Third scenario: Diode and machine
Diode and machine is a traditional and more reliable solution, the old and new systems is not limited.
But disadvantages are:
1. There diode voltage drop is high energy consumption
2. Capacity is limited, we do 400A as highest one
