Converter 100W 9~18V-12V 8.3A DDR-120A-12

Universal DC/DC converter for demanding applications

The DDR-120A-12 converter is a robust and reliable power source, designed to operate in harsh industrial conditions, as well as in railway applications. The device converts the input voltage from 9-18V DC to a stable output voltage of 12V DC, delivering a current of up to 8.3A and a power of up to 120W. Its compact dimensions (32x125.2x102mm) and the possibility of mounting on a TS-35/7.5 or 15 DIN rail facilitate integration with existing systems.

Safety and compliance with standards

The DDR-120A-12 model meets the stringent standards of EN50155 (on-board electronics for railway vehicles) and EN45545-2 (fire safety in railway vehicles), making it an ideal choice for railway applications. Protections against short circuit, overload, overvoltage and reverse polarity guarantee safe and reliable operation of the device, protecting both the converter itself and the circuits connected to it. Additionally, input/output isolation at 4 kVdc provides a high level of electrical safety.

Functionality and efficiency

The converter is characterized by high efficiency (88.5%), which translates to minimal energy losses and reduced operating costs. The ability to briefly overload up to 150% allows for trouble-free starting of devices with high starting current - e.g. electric motors - without the risk of damaging the converter. The lack of required minimum load provides flexibility in application and allows for efficient energy use even with low power consumption. Output voltage adjustment allows for precise adjustment of power supply parameters to the needs of a specific application. Cooling is done by free air convection, which eliminates the need for additional fans and reduces the risk of failure related to their damage.
