(1)
Operates down to zero load with reduced regulation.
(2)
Forced Air cooling can be needed depending on the housing in which the SMPS is used – the temperature warning open drain
output signal can be used to control a fan.
(3)
The 50-V output will not power up, unless the ±15-V outputs are loaded. It is recommended that you load these outputs with 75
Ω during power up.
