Mobile devices are part of our everyday life and have to be available everytime, everywhere. It is all the more important to recharge the battery in time and fast. The new USB-A charging jack from Schlegel has been designed to do exactly that. The jack has 2 USB-A ports, each providing a charging current of 2.4 A at an output voltage of 5 V. This way, two devices can be charged at the same time at “lightning speed”.
But not only the charging capacity is convincing, the scope of functions for safe operations does as well. The jack comes with a current limitation of the output current of each USB port, including also a protection against short-circuit, undervoltage and overvoltage.
Overload protection
The charging jack can be operated within a temperature range of -40 °C to 70 °C. When the environmental temparature rises, a temperature sensor ensures that the electronics do not heat up too much. It regulates the charging current correspondingly or even switches off the charging process automatically when critical temperatures are being reached. Only after the temperature returned to the uncritical state the charging process will be continued. Additional ventilation slits ensure a continuous cooling, especially when the circulation of air is restricted due to the mounting situation.
The robust USB-A charging jack has a mechanical lifetime of min. 5000 plugging cycles and is constructed for a panel cut-out of 30.5 mm. The operating voltage ranges from 15 V to 30 V DC. The electrical connection is provided with a spring-load terminal for cable cross-sections from 0.2 to 2.5 mm².
The new SCHLEGEL charging jack is also suitable for railway applications as all relevant parts of it comply with the standards EN 50155, EN 61373:2011 class 1B, EN 60077-1, EN 45545-2, EN 60068-2, EN-50121-3-2, IEC 61000-6-3/4, EBA EMV06.
SCHLEGEL currently offers 2 versions of the charging jack: KRJSW_2USB_A_5V with black front bezel and KRJM_2USB_A_5V with silver-coloured front bezel.
