The LRS-50-12 is another model in the family of low-profile power supplies. The 50W power supply has a smaller size and higher efficiency compared to the previous generation RS-50
The device can be powered from a wide range of input voltage 85-264V AC or 120-373V DC, while the output is available 12 VDC voltage which the user can adjust (within ± 10%) using the built-in trimmer.
It is worth emphasizing that the power supply can withstand temporary (5s) input voltage up to 300V AC thus increasing its reliability. The model uses a number of protections such as: short-circuit, overload, overvoltage. Ventilated metal casing with a low profile (height 30mm) allows the device to be used with an open air circulation.
In comparison to RS-50, the temperature range has been extended and for LRS-50 is from -30 ° C to + 70 ° C. Resistance to vibration up to 5G enables the use of power supplies wherever we deal with vibrations and shocks. The LRS-50-12 meets a number of safety standards, including UL, CUL, TUV, CCC, CB and CE certificate. An important aspect is also a competitive price - lower by more than 20% compared to RS-50.
Thanks to special brackets, the power supply can be installed vertically or horizontally on a DIN rail. The new LRS-50 model will meet the requirements of users who value quiet operation, energy efficiency and high efficiency. It is dedicated to applications in automation systems, mechanics, electronics, and in all places where a low power supply profile is required.
