Mechanical Data
Safety (continued)
The galvanic isolation is verified in an electric strength test. The
test voltage (VISO) between input and output is 1,500 Vdc or 60 sec.
Leakage current is less than 1A @ 50Vdc.
Flammability ratings of the terminal support and internal plastic
construction details meet UL 94V-0.
A fuse should be used at the input of each PKM 4000 series power
module. If a fault occurs in the power module, that imposes a short
on the input source, this fuse will provide the following two functions:
Isolate the failed module from the input source so that the
remainder of the system may continue operation.
Protect the distribution wiring from overheating.
A fast blow fuse should be used with a rating of 10A or less. It is
recommended to use a fuse with the lowest current rating, that is
suitable for the application.
