*1 The GOT is an open type device (device installed to another device) and must be installed in a conductive control
panel. The above test items are conducted in the condition where the GOT is installed on the conductive control
panel and combined with the Mitsubishi PLC.
*2 QP: Quasi-peak value, Mean: Average value
*3 The above test items are conducted in the following conditions.
30-230MHz QP
230-1000MHz QP:47dB
Test details
Electromagnetic emissions from the
product are measured.
Electromagnetic emissions from the
product to the power line are mea-
sured.
Immunity test in which static electric-
ity is applied to the cabinet of the
equipment.
Immunity test in which field is irradi-
ated to the product.
Immunity test in which burst noise is
applied to the power line and signal
lines.
Immunity test in which lightening
surge is applied to the product.
Immunity test in which a noise
inducted on the power and signal
lines is applied.
Test for checking normal operations
at instantaneous power failure
Test for checking normal operations
when the power supply unit input
voltage is fluctuated
Test for checking if the unit becomes
faulty with a transient voltage of the
internal and external input sides of
the power supply unit or unit power
