Transformer Soft Start Relay
Satronix offers a Transformer Soft Start Relay for use in switched filament or welding transformers applicable in plant construction and in durable packing facilities. This relay prevents inrush current during transformer start by using the concept of pre-magnetization of the transformer. The strength of pre-magnetization is the same for all transformers and its value should amount to the turning point of the hysteresis curve this product.
The Transformer start SSR pre-magnetizes prior to complete switching using uni-polar voltage impulses.
Adjustable start time - the width of the required voltage impulses matches the different transformer types.
