Description and resources

The DC Transformer 343L-12-SD stands out to its low noise and very high efficiency, making it to a superior power supply in high end applications with different voltage buses. The tranformer 343L-12-SD is a member of the 300 series push-pull power converter with a bipolar and one additional single output voltage bus. The transformer includes a softstart, an input undervoltage lockout and a permanent short circuit protection to ensure efficient module protection. The soft start allows current limitation and eliminates inrush current during start up. Since the transformer is voltage and current regulated, the module passes into constant current mode, when an overload or even a short circuit is applied. This feature makes this transformer unique in limiting the maximum output power. The device immediately restores to normal operation when the overload is removed and is able to deliver the full output power within the specified temperature range.
