TESAV, AC & DC input, 50W - 1000W

AEPS-GROUP TESAV series with AC and/or DC input have separate input for AC voltage to supply voltage to an inner full bridge rectifier. Its output is connected to the input of the inner DC/DC converter, which input is also one of the units inputs. These outputs also server for filtration of rectified DC via connecting external electrolytic capacitors to the DC inputs. Basically in such case the unit becomes AC/DC with external input capacitor bank. Advantage of such design is that it gives an ability to place an electrolytic capacitor in a “cold” spot while the unit itself works with high operating temperature, much higher than what’s allowed for the external capacitor.

Such trick helps significantly increase MTBF, i.e. increase the reliability of the whole power supply.

The inputs for external capacitors can also be used as a separate or secondary input for DC primary source connection, i.e. a capacitor bank, creating an uninterruptible power supply.

TESAV units are designed for special AC inputs: 36 (25-53 VAC), 115 (80-140 VAC) and 230 (176-242 VAC). Also it’s allowed to connect DC voltage of any polarity to the AC inputs, with voltage ranges of 36-75 VDC, 82-198 VDC and 175-350 VDC respectively. A special DC input can be used – 150W (110-350 VDC). The units have high power density values from 0,98 kW/dm3 to 3,6 kW/dm3. The series are designed in robust aluminum cases with mounting flanges. Increased efficiency allows maximum operating case temperature range up to -60…+110 °C on request.

Optimal for application fields 1, 2, 3, 4, 5, 6, 7, 9, 10, 11.
