Structure of the 6 Phase Electrical Protection Relay Test Kit
1)LED working indication: LED flashing means waiting for work, LED always on means working.
2)Communication interface: The communication is an external notebook computer interface, and the instrument can be controlled through an external notebook computer.
3)USB interface: general interface, can be connected to USB2.0 devices such as mouse, keyboard, U disk, etc.
4)Switch input: used to collect the output switch signal of the protection device and measure time.
5)Switch output: used to control other devices, passive nodes, with a maximum capacity of AC220V/1A.
6)Device auxiliary power supply: It can output DC ±110V power supply, and the maximum current output is 2A, which can supply power to the protection device.
7)The first group and the second group of current output terminals: IA, IB, IC, Ia, Ib, Ic, IN is the common terminal. The LED is on to indicate that the current source is open.
8)The first group and the second group of voltage output terminals: UA, UB, UC, Ua, Ub, Uc, UN are common terminals. The LED is on to indicate that the voltage source is short-circuited.
9)Touchpad: Similar to the laptop touchpad, it can be touch-controlled in all directions. Left and right keys: the left key is the confirmation key, and the right key can view the file properties.
10)Keyboard: Used to input fixed value data.
11)Display screen: The display is a 10.4-inch LED LCD screen.
