Circuit for a transistorized disconnector-connector of the VRLA accumulator battery

摘要

The VRLA battery -coupler transistor system is applicable to the power supply systems of telecommunication facilities and is used to disconnect battery 48 -V batteries from the power circuitno AC /DC and its simultaneous connection to the input of the "available battery capacity" meter.In the system according to the negative battery clamp (-Bat) the transistor tubes of the first (T1) and the third (T3) are attached,where the first transistor (T1) is connected to the second transistor (T2) in series as follows,that the sources of both transistors are interconnected and connected to (A) the sources of the transistors of the first (T1) and the second (T2),and the gates of the first (T1) and second (T2) transistors are connected and connected to the contact (B) of the first (T1) and second (T2) transistor gates;and the second transistor drain (T2) is connected to the negative gym clamp (-Sil).
