When designing the cabinet, please consider the design of the module air inlet duct.

Function description of 1.4G05H1 and G07H1
A. protection function
Output overvoltage protection
The output voltage is too high for the electric equipment will cause catastrophic accidents, to prevent the occurrence of such situations, our company has a high frequency module overvoltage protection circuit module, automatic deadlock overvoltage, the corresponding module fault indicator, automatic withdrawal work fault module without affecting the normal operation of the whole system; overvoltage protection for 320V 2V (G05H1, G07H1).
Output current limiting protection
The output power of each module is restricted, the output current can not be increased indefinitely, so each module output current is limited to 1.05 times the rated output current, if the overload, lower output voltage by automatic module protection module.
Short circuit protection
The output characteristics of the rectifier module, output short circuit module in an instant the output voltage down to zero, limiting the short-circuit current in the limiting point, the module output power is very small, in order to achieve the purpose of protection module. The module can work in short circuit for a long time and will not be damaged. The module can be automatically recovered after troubleshooting.
Module parallel protection
There are parallel protection circuits in each module, which ensures that the fault module exits automatically without affecting other normal modules. Modular parallel output diagram as shown in the following picture.
Over temperature protection
Over temperature protection is the main protection for power converter device, limit junction temperature and current overload capacity of these devices are safe, normal working condition, the system design with enough margin, but in some special conditions, such as the ambient temperature is too high, the fan stops, module testing radiator temperature exceeding 85 DEG C when will the automatic shutdown protection, reduce the temperature to 70 DEG C when the module starts automatically.
Overcurrent protection protection main power converter device, in each cycle of variable flow, if the current exceeds the device to withstand current closed power devices, power devices to achieve the protection. Over current protection can be automatically restored.
B. settings function
Voltage regulation function
At the back of the module, there is an output voltage regulator potentiometer, which can adjust the potentiometer to change the output voltage without module monitoring. When the module is monitored, the output voltage is set by the monitoring system, and the potentiometer is invalid.
Stepless current limit
The limiting point can be set in the rated current of 20%-105% by monitoring system.
Remote control function
Remote control module, the on / off / float voltage conversion.
Technical features of 1.5G05H1 and G07H1 modules
A. electrothermal plug and play technology
Through long-term research, our company has solved the problems of high current connection and device protection of live connection. The rectifier module is designed as a hot swappable module, the replacement is very convenient, the replacement of a module is only a maximum of 30 seconds, the system maintenance is safe, simple and efficient.
B.ZVS soft switching technology
In order to make the switching power supply can efficiently operate at high frequency, we continue to research and development of high frequency soft switching technology, has successfully developed ZVS edge resonant technology, switching loss is reduced, so as to further reduce the volume and weight and greatly improve the performance of the module.
Advantages of a.ZVS soft switching
Small switching loss
It can realize high frequency (the limit frequency can be 1-2M), and the switch process is realized in smooth state
Constant frequency operation, small harmonic component
Absorption free circuit
The current and voltage stress of the power tube is small
Basic principle of b.ZVS soft switching
The power loss of MOSFET consists of three parts: the power loss, turn off losses and conduction losses, hard switching voltage during switching and current change at the same time, there is high voltage and large current state, the loss is very large, which leads to the low efficiency, power tube temperature, need to transfer the switching loss absorption circuit.
The switching process of ZVS soft switch in opening VDS down to the current rise 0V, turn off the current reduced to VDS increased by 0A, thus theoretically no switching losses, although the actual VDS and current changes or there will be some overlap, but the switching loss and hard switching compared greatly reduced.
The voltage and current of the ZVS soft switch are smooth, and the VDS has no overshoot, so the output harmonic component is small and the electromagnetic interference is small.
