Description and resources

The DC Transformer 145-12-SD stands out to its low noise and very high efficiency, making it to a superior power supply for mobile and high end industrial applications. Full advantage of this wall mounted power supply is taken when mounted directly on a heatsinking surface area. The DC Transformer 145-12-SD is a member of the 100 series step down power converter with synchronous rectification and a shut down option. 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 is able to deliver the full output power within the specified temperature range.
