The principle of this kind of amplifier push-pull amplifier is shown in the figure. The two-tube DC circuits of the output stage are connected in series, and the AC circuits are connected in anti-parallel. Each component constitutes a bridge, in which the two arms are the internal resistance of the tube, and the other two arms are the internal resistance of the power supply GBI and GB2. RL is a load with a tapped ground.

New tube push-pull power amplifier circuit



7.62MM Power+ Signal Power Connector

power connector is used in power module system. It can select the matching power + signal connector according to the need. The feature is that the number of power and signal contacts and the matching sequence can be selected arbitrarily while keeping the connector size and contact core number unchanged.

Plug (male) / socket (female) can be installed at 90 or 180 degrees. It supports mixed or independent combination of signal and power. The quantity range of power and signal is (2-16) pin and (12-128) pin respectively


Product features

High temperature resistant, glass fiber reinforced and flame retardant polyester is used as insulation material

Copper gold composite conductor with high conductivity is used, and the contact area of the conductor is plated with gold
It adopts shrapnel contact, which has the characteristics of integration, small volume, large current carrying capacity, soft plug-in, blind plug-in, self guidance and high dynamic contact reliability. This series of products can be interchanged with FCI's powerblade series and Tyco's multi-beam series
There are three sizes of center distance of power contact: 5.08mm, 6.35mm and 7.62mm

The length of power hole / signal pin can be selected in two sizes. The power rated current is 45A and the signal rated current is 2.5A
