When the fluid flows in the pipe, the fluid filled with the pipe flows through the throttling device in the pipe, causing local contraction near the throttling device, increasing the velocity, and generating static pressure difference on both the upper an
G2040PV dc power surge protectors are routinely presented to lightning and over voltages, which can impressively lessen the coveted future. G2040PV are directly involved with our Photovoltaic electrical systems to provide a discharge path to the surges or
The 6N137, HCPL-2601/2611 single-channel and HCPL-2630/2631 dual-channel optocouplers consist of a 850 nm AlGaAS LED, optically coupled to a very high speedintegrated photodetector logic gate with a strobable output.
According to the connection mode of the switch ,this small power electric switches can be divided into single-controlled small power electric switch, double-controlled small power electric switches, double-pole (double-circuit) double-controlled small pow
