The advantages of 48V control voltage are as follows:
The power consumption of the control circuit transmission line itself will inevitably produce a voltage drop, which will cause the terminal voltage to be lower than the initial voltage, and a long-term under-voltage will cause electrical component failure.
In order to ensure that there is enough voltage at the end to control electrical components (such as contactor pull-in), methods such as increasing the input voltage or increasing the line section are usually adopted.
Increasing the cross-section of the wire will increase the cost accordingly. For this reason, the method commonly used in Europe is to increase the input voltage. However, in order to ensure personal safety, the control voltage is usually not higher than the safety voltage. The safety voltage of Chinese and international standards is 50V, so Europe usually chooses 48V as the control voltage.
Kinocranes uses 48V as the standard configuration of the control voltage, which not only meets the requirements of national standards, but also increases the working stability of electrical components. This is our advantage.
Tips: The control voltage of electrical components such as contactors is also divided into 24V, 36V, and 48V.
In the demand analysis stage, especially when encountering retrofit projects, you need to pay attention to the following points:
When the customer’s original control voltage is 36V, it is necessary to state the advantages of the 48V control voltage, and it is recommended to change it to 48V, adding a 48V transformer to the electric cabinet of the cart;
If it is changed to 48V, it needs to be specified in the contract to remind the electrical department of the special design.
