CONDITIONS/DESCRIPTION
AC/DC indicator - This signal indicates the status of the AC input or DC outputs.
When there is sufficient AC voltage and the outputs are operating normally, an
open collector signal is provided.
Turn-On delay time from application of AC:
Warning time before outputs go out of regulation:
Warning time before outputs deviate ±10% from the nominal value:
Provided on dual-output models. Open collector signal intended to drive an LED.
Closed collector occurs when the Power Good Signal is in its open collector state.
Protected against overtemperature conditions.
Unit recovers when overtemperature condition is removed.
Provided on dual-output models. Up to 4 units can be connected in parallel.
There are some limits for parallel operation. See MPB125 Applications Note.
N+1 redundancy is provided. V2 needs an external isolation diode for N+1 operation.
An external diode is required on MPB125-2003 and MPB125-2005 models for
redundancy on both V1 and V2, or when ordering, you can specify MPB125-2003D or
-2005D which have an internal isolation diode.
Internal isolation diode is provided on V1 for all dual-output models except the
MPB125-2003 and MPB125-2005. Specify MPB125-2003D or MPB125-2005D,
respectively, if an internal isolation diode is required for these models.
