BES-307CT
70 Watt
- 18…56 VDC input range
- Operating temperature 0…+50 °C
- Installation height only 38 mm
The widerange input voltage of 18…56 VDC provided by the DC/DC converter BES-307CT includes the typical voltages 24 V, 28 V, 36 V and 48 V. It was especially developed for industrial and mobile computer systems with low power requirements. The possible fields of application for the BES-307CT are enlarged further by its compact design and fanless operation.

Max. output power must not exceed 70 W. Ripple and noise was measured by a 15 MHz bandwidth limited oscilloscope with connected 0.47 µF ceramic capacitor at each output. For connection to a low voltage mains supply an additional input filter may be required.
As a power component this PSU is for assembly purposes only and must not be operated in unassembled condition. The final assembly has to comply with the valid EMC and safety standards.
