6. Overheat Protection
To prevent burning out the windings as a result of overheating,
MRS18V2
type fans have been designed with a protector

5. Noise Protection
5.1 Protection from noise coming in from the power line
The
MRS18V2
type do not have filters against power line noise.
When fans are used in noisy environments caused by high-output control and switching, the fan rpm will become unreliable.
Common causes of noise include high-output motors, solenoids, high-frequency power supplies and electric welders.
Commercial LC filters are very effective against external noise.
For a noise filter, we recommend the ORIENTAL MOTOR
ZCB2203-11S
(sold separately)
5.2 Preventing noise from being discharged externally from the power line
The
MRS18V2
type use triacs for phase control, which can cause noise that affects other equipment.
A commercial LC filter is an effective way of reducing that noise.
