Description and resources
The DC Transformer 154-12 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 tranformer 154-12 is a member of the 100 series switching regulator. 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 type 154-12 is voltage and current regulated, the transformer passes into constant current mode, when an overload or even a short circuit is applied. This feature makes the module unique in limiting the maximum output power. The transformer immediately restores to normal operation when the overload is removed. The device is able to deliver the full output power within the specified temperature range.
