NOTES
1
Absolute maximum ratings are limiting values, to be applied individually, and beyond which the
serviceability of the circuit may be impaired. Functional operability under any of these conditions is
not necessarily implied. Exposure of absolute maximum rating conditions for extended periods of
time may affect device reliability.
2
Measured at the remote sense points.
3
Unit regulates output voltage to5W load.
4
Open remote sense connection.
