MH005-Series Power Modules:
Electrical Specifications (continued)
Table 2. Output Specifications (continued)
* At less than the minimum current, units will continue to operate; however, the single-output modules (MH005A, B, C) may exceed their output
ripple specification. The dual-output modules (MH005BK, CL) may exceed their output voltage regulation limits if the output currents are
severely imbalanced with one output sourcing less than the minimum current.
† Output not in current limit is held at minimum load to give the worst-case (highest current level) inception point.
