Shown for the first time at Drives & Controls last month, the new Wipos
50-480W switch-mode power supply from Wieland features 'temperature
prompted power limitation', which automatically reduces power output at
potentially damaging ambient temperature levels. In the event of a power
load exceeding the upper temperature limit, the device switches off and
enters a 'hiccup' mode - a periodic monitoring of the output that
continues until the load is back within range, whereupon the power supply
is restored. Wipos power supplies can be connected in parallel to
increase power output, or used with de-coupling diodes to provide dual
redundancy. Efficiency is around 90% and the 480W unit takes just 68mm of
rail mounting space.
