Embedded THK series DC power supply device is a new type of DC power supply equipment, mainly used in small switching station and user terminal for two control circuit (such as microcomputer protection and intelligent terminal indicator, analog indicator etc.) to provide uninterrupted power supply reliable, to avoid the loss of electricity in exchange for microcomputer protection without protection effect of solution for operation over voltage and harmonic factors such as the failure of UPS can lead to failure of microcomputer protection. At the same time, it can also provide DC operation power supply for primary switch equipment (spring mechanism vacuum circuit breaker, permanent magnet mechanism vacuum circuit breaker, electric load switch etc.).

The THK series embedded DC power supply device has two ways, the power input and the PT input. The output mode is from DC220V to DC24V specifications, which can meet all kinds of applications. The maximum output power of the device can reach 600W, which can meet the needs of different loads.

THK series of embedded DC power supply devices are small in size and easy to install and connect. It is suitable to be installed in various types of switching equipment. It is more reliable and economical than the general DC screen system, which is more obvious to the small user terminals. It also saves space for occupying space, reduces line losses and installation works, and maintains conveniently. It provides a new alternative for power system reliability.

The THK series of embedded DC power supply adopts high frequency power technology, and the battery is maintained by automatic charging management module, which greatly prolongs battery life and makes the device run more safely and reliably. The device has the function of communication and alarm, and can easily realize remote automation management of unattended.

Product features

1, disperse and install, save the area and reduce the cost

According to the design idea of embedded system, the NMK series embedded DC power supply device is directly installed in the instrument box of the intelligent switchgear (or the electric box of outdoor device), which saves the occupied area of the DC screen.

Because the power in the switch cabinet, can reduce the usage of cable, saving equipment investment and a cable construction workload; while in the total number of units, the price lower than DC system, can reduce the total cost of the project; at the same time can reduce the line loss, reduced spare parts in operation, saving operating costs.

2. The reliability of embedded power supply is greatly improved

With the embedded power supply mode, when a loop is in trouble, the power supply of other circuits will not be affected, so that there will be a bit of trouble. There will be no operation power in the whole station, and its overall reliability will be greatly improved compared with the centralized power supply DC screen.

3, a variety of input and output methods, wide range of application

THK series can provide DC 220V, 110V, 48V, 24V output according to customer's needs. The range of AC input is 85 ~ 265V, which is flexible for PT and power supply.

4, intelligent management and maintenance

Intelligent high frequency power supply technology, self monitoring, self diagnosis, local display, alarm, and network communication, to realize automatic remote management of unattended.

Automatic charging management module built-in battery, automatic battery intelligent management are floating, greatly delay the life of battery, make the operation more reliable and safe.
