* Note: 12.0VO (B) device codes have an adaptable extended Turn-On Delay interval, Tdelay, as specified for B* devices. The extended Tdelay will occur
when a 12VO module restarts following either 1) the rapid cycling of Vin from normal levels to less than the Input Undervoltage Lockout and then back
to normal; or 2) toggling the on/off signal from on to off and back to on without removing the input voltage. The normal Turn-On Delay interval, Tdelay
,
as specified for All Devices, will occur whenever a 12VO module restarts with input voltage removed from the module for the preceding 1 second.
12.0VO (B) also achieves +10% VO, set Remote Sense drop or trim up to 110% VO, set only above Vin = 40Vdc
