GE VMIVME-017807-414001 350-0001007807-414001 D
GE VMIVME-017807-414001 350-0001007807-414001 D has a high output driving current, slow response, and mechanical lifespan. It is suitable for driving intermediate relays, contactors, coils, indicator lights, and other low frequency applications. GE VMIVME-017807-414001 350-0001007807-414001 D has low output driving current, high frequency, and long lifespan, making it suitable for controlling servo controllers, solid-state relays, and other applications that require high frequency and long lifespan. In high-frequency applications, if it is necessary to drive a large load at the same time, other devices can be added
At the moment of controlling the opening and closing of inductive loads such as contactors, due to the non mutable current characteristics of inductors, according to U=L * (dI/dt), GE VMIVME-017807-414001 350-0001007807-414001 D will generate a momentary peak voltage between the two contacts of the relay, which exceeds the voltage reduction of the relay’s contact withstand voltage; The electromagnetic relay used in the relay has a withstand voltage of 1000V (1min) between the contacts. If the voltage between GE VMIVME-017807-414001 350-0001007807-414001 D contacts works for a long time at around 1000V, it is easy to cause metal migration and oxidation of the contacts, resulting in increased contact resistance, poor contact, and contact adhesion. And the faster the action frequency, the more serious the phenomenon becomes. The instantaneous high voltage is shown in Figure 2, with a duration of less than 1ms and an amplitude of over 1KV. This problem also exists when the transistor output is an inductive load, and the instantaneous high voltage may cause damage to the transistor.
