Short circuit protection
Floating output
20ms hold-up time min.
This series of 100 Watt to 220 Watt single output switchers use an advanced
circuit topology providing superior performance at low cost. Smaller and lighter
than equivalent linear supplies, they are available in 5V and 24V output versions.
The floating outputs can be referenced as either positive or negative. The SL120
model is UL, CSA and VDE approved. Also, selected models incorporate remote
sense. SL120/220 Series power supplies are suitable for a wide variety of
applications, including front end power systems, general industrial and telecom
equipment.
