Did you know

The DSE557 is an Automatic Mains Failure (AMF) and Mains Parallel Control Module. It is now considered obsolete and has been replaced by the DSE8620 MKII.
The DSE557 was part of the DSE5xx series, which included other modules like the DSE550, DSE555, and DSE560. This series was designed for front panel mounting and offered comprehensive instrumentation and load control features.
The DSE557's key strengths included its ability to handle single-set parallel operation with the mains, offering 'soft' no-break return and peak lopping functionality for cost savings. It also provided a 'no break transfer' during test on load facilities, ensuring continuous power supply.
