TRANSISTOR board 4 ch V 3.2

Transistor boards for direct current control.
PWM operation up to 20 kHz (data tested on an oscilloscope for flooding horizons) The control is controlled by ground control, since such transistors are cheaper and more efficient. A diode has been added to dampen reverse pulses from pumps
The board has an external power connector and a jumper for switching between external and internal power
Separate LEDs are used on the board
Both versions of the board have:


8p8c input for connecting to the main shield;
External power input (for connecting an external power supply, supported from 5 to 100 V, 150 W)
Jumper for switching between shield power and external power supply
Quick-release contacts for connecting the load
Mounting holes for M3 screws (94x54 mm)
Specifications
External power supply voltage: 5-100 V
Recommended load power when connecting power from the shield : 6 watts per socket
Maximum load power when connecting power from the shield: 18 watts per socket
Recommended load power when connecting an external power supply: 30 watts per socket
Maximum load power when connected to an external power supply: 50 W (150 W short-term)
