Now, the PMC-A is ready for use.
Inrush Current
When the power switch is turned on, the maximum inrush cur-
rent of 30 A for type I and 80 A for type II may flow. In partic-
ular, with a system using multiple units of the PMC-A, when
the power switch is turned on at the same time, make sure that
there is enough of a margin, taking into consideration the
capacity of the power distributor panel or the AC power line.
Reverse Polarity
When the current or voltage is set up as zero with the OUTPUT
switched off, a 0 V to 0.6 V reverse polarity voltage can arise.
Because of this voltage, an opposite-directed 1 mA current
flows to the load. Note that this load can reduce the life time of
the product.
