Noise Terminal Voltage According to
EN55011
The G3NA-UTU complies with EN55011 standards when a capacitor
is connected to the load power supply as shown in the following
circuit diagram.
•
Connect capacitor C1 to both sides of the input terminals for a
G3NA with a DC input.
•
Connect capacitor C2 to both sides of the load power supply
output.
•
Connect the varistor to both sides of the G3NA output terminals.
•
Do not use an input line that is longer than 3 m.
Loss Time
The loss time will increase when the G3NA is used at a low applied
voltage or current. Be sure that this does not cause any problems.
Using DC Loads
For a DC or L load, a diode should be connected in parallel the load
to absorb the counter electromotive force of the load.
Fuses
Connect a quick-break fuse in series with the load as a short-circuit
protection measure. Use one of the fuses in the following table or
one with equivalent or better characteristics.
Recommended Fuses
Reverse Connection
The output terminal side of the G3NA-D210B is connected to a built-
in diode to protect the SSR from damage that may result from
reverse connection. The SSR, however, cannot withstand one minute
or more if the wires are connected in reverse. Therefore, pay the
utmost attention not to make polarity mistakes on the load side.
