The output protection relay output can be externally protected in case the inductive load produces parasites by :- rheostat or RC module, AC - free wheel diode, DC. The external thermal fuse is connected to the output common power supply to protect the output connected device. 1.4.7.4 Cabling of the CS 31 bus The CS 31 bus is an RS 485 serial interface consisting of shielded twisted pair cables. This bus is a master/slave bus and only a single master bus is accepted. Use AWG 24 (0.22mm 2) to AWG18 (0.18 mm 2) twisted pair. The maximum length is 500 meters. The same cable type should be used throughout the system bus setup. For example, bus interruptions should be avoided during cabinet cable connections, otherwise they should be connected to the same side of the patch board. Warning: Bus STAR connection not allowed! Central and remote devices can be connected at any point on the bus :- Bus 1 on bus 1- Bus 2 on bus 2- Shielding (preferably braided) and main stage ground on terminal 3 on terminal block 1 (cable <1 m). The bus should be connected at 120Q to a 1/4 W resistor at the bus terminal. Twisted pair should be symmetrical.

Voltage feedback module is an electronic component, which can stabilize the output voltage, improve the stability of the circuit, reduce the output impedance, and reduce the output voltage error.

There are many types of voltage feedback modules, such as DC voltage negative feedback module, AC voltage negative feedback control module and so on.

The function of the 81007-465-51-R-2 power supply feedback module is to compare the feedback signal of the output voltage with the reference voltage signal, so as to control the stability of the output voltage.

A power feedback module usually consists of an amplifier, a comparator, and associated circuits. When the output voltage changes, the feedback signal will also change accordingly, the amplifier amplifies the signal and compares it with the reference voltage, and controls the stability of the output voltage according to the comparison result.

81007-465-51-R-2 Power module is a power converter that can be directly welded and inserted on the circuit board, which is generally divided into AC to DC or DC to DC according to the conversion method. It is essentially an integrated circuit board unit that does not provide the function of power, that is, it is not a battery, but a part installed in the battery pack. With the development of science and technology, the volume of power supplies tends to be modular and miniaturized, so there is a power module. The main circuit of the switching power supply is integrated into the chip circuit, which can realize the functions of broadband modulation, isolation and a variety of protection.
