The TUNS series from Cosel is an exceptional power supply in several respects. Firstly, the power supplies of this series are extremely compact. The power ranges from 50 to 1200W and the 700W has the dimensions of a smartphone, for example. It has a small surface area, but it is also extremely flat. In addition, the operating temperature may vary between -40°C and even +100°C, and all this without derating (loss of power).
TUNS Series by Cosel
These TUNS power supplies have an input range from 85 to 264VAC, which means they can be used worldwide. The power supplies also have a built-in active PFC circuit, which achieves a power factor of almost 1.
The fact that they can handle high peak currents can be very interesting for applications that demand higher power for a short time, but lack the space for a heavier power supply. Furthermore, there is the possibility of parallel switching and a remote on/off is provided to limit the standby power. The output voltage is adjustable and a remote sense is provided.
The standard TUNS series requires a number of external components with the advantage of being able to control a number of parameters yourself. For example, by fitting the right capacitor, the hold-up time can be extended if required. The values of these external components are clearly indicated in an application note. If you want a solution that is directly applicable and in which these external components are already included, then you should choose the TUNS/SN series. The following series types are already available: 50W and 100W.
