which typically occur in most installations, but especially in
battery driven mobile applications. The M-family has been
successfully tested to the following specifications:
EMC and Immunity to Input Transients
A suppressor diode or a metal oxide VDR (depending upon
the type) together with an input fuse and an input filter form
an effective protection against high input transient voltages
units are available on customer's request. Standard DM units
(110 V battery) will not be damaged, but overvoltage lock-out
will occur during the surge
