The Liteway® PS-1210S is a compact switching stand-alone or rack mountable
power supply that can be used to power multiple Liteway fiber optic
transmission systems from a 90 to 240 volt 50/60Hz source.
The PS-1210S has power, alarm and overload indicators as well as internal
circuitry that will protect the unit in the event of an overload. Should
such an overload occur, the power supply output will immediately drop to 0
and then automatically reset itself when the overload is removed. The
PS-1210S also has the ability to be paralleled for redundant operation when
This efficient supply is compliant with the US Energy Independence and
Security Act of 2007 and current California Energy Commission (CEC)
