BES-307VC
70 Watt
- 10…30 V input range
- 50 Watt continuous fanless power
- Operating temperature 0…+50 °C
The DC/DC converter BES-307VC was developed for industrial and mobile computer systems with low power requirements. Due to its input voltage range of 10…30 VDC it can be univer-sally applied, for 24 VDC industrial networks and in the automotive branch. The possible fields of application for the BES-307VC are enlarged further by its compact design and fanless operation.

With max. load at +5 V / 10 A and +12 V / 1.5 A a minimum load of -12 V / 0.1 A must be connected. With max. load at +5 V / 10 A a minimum load of +12 V / >0.2 A and -12 V / 0.03 A must be connected.
* When the minimum load requirements are not observed, the input voltages can rise and damage the connected consumer loads.
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.
