Product name

　　High-performance primary maintenance electrician and skill assessment training device

　　Model (Type)

　　BF_HK-G201

　　Feature

　　1. Main control function board

　　(1) The three-phase four-wire power input, after passing through the leakage protector, through the main switch, is operated by the contactor through the start and stop buttons;

　　(2) There are three 450V pointer AC voltmeters to indicate the three-phase voltage of the power input;

　　(3) Timer and alarm recorder (service manager), which is usually used as a clock, with functions such as setting the experimental time, timing alarm, and cutting off the power supply; it can also automatically record leakage alarms and instruments caused by wiring or operation errors. The total number of over-range alarms provides a unified standard for the assessment of students' experimental skills.

　　2. AC and DC power supply

　　(1) Excitation power supply: DC 220V/0.5A, with short circuit protection.

　　(2) Armature power supply: DC 0～220V/2A continuously adjustable power supply all the way, with short circuit protection.

　　(3) DC regulated power supply: ±12V/0.5A two channels, +5V/0.5A one channel, with short-circuit soft cut-off automatic recovery protection function.

　　(4) AC power supply: 1. There is a set of transformers. The primary side of the transformer can add 220V or 380V AC power according to different wiring. After closing the switch, the secondary side of the transformer can output 36V, 110V, 20V, 20V , 12V, 6.3V AC voltage; ②, with a set of single-phase voltage regulator, can get AC 0 ~ 250V adjustable voltage; ③, the control panel is equipped with single-phase three-pole 220V power socket and three-phase four-pole 380V Power outlet.
