Eliminating Voltage Spikes |
|
Voltage spikes from 300V to 500V can occur momentarily when a relay is switched off. Sensitive electronic equipment can be damaged or malfunctions can occur if these spikes reach the vehicle electrical network without supression. A relay with a diode eliminates voltage spikes completely. |
