High frequency switching power supply

main feature:

1, high efficiency and energy saving - high efficiency, environmental protection and energy saving and different process principles, it can save 20% -30%

2, high-speed reaction --- switching power supply operating frequency is about 30KHz, very sensitive to input changes and load changes, fast response [microsecond level] efficiency can be higher than 95%, ripple factor can be less than 0.5%;

3, Bomei Power High-power high-frequency switching power supply generally considers the use of N+1 redundant backup system:

(1), parallel advantage: Under normal circumstances, all module units are involved in the work. Once one of the modules fails, the system automatically withdraws the faulty unit, and the other modules share the faulty unit current, so that the total output voltage and current remain unchanged. At the same time, the faulty module can be taken out for maintenance, the equipment is not stopped, and the full load is continued, which greatly improves the reliability of the power supply;

(2), each machine has 485 communication motherboard, equipped with high-definition intelligent display, high output accuracy, energy saving and high efficiency.

The main advantages are: the high-frequency switching power supply adopts the IGBT power module of international famous brand company; the main transformer adopts imported nano-crystalline magnetic material, the newly upgraded line control technology, and the intelligent soft-switch synchronous rectification technology guarantees continuous operation for 365 days and 24 hours. run;

4, the machine has: high efficiency, full sealing, anti-corrosion, moisture-proof, waterproof, shockproof, anti-radiation, anti-interference and over-current, over-voltage, over-temperature, short-circuit, lack of equal automatic protection alarm function, can effectively protect the power supply It enhances the life of the power supply itself.

5. Overcurrent protection: The system can effectively protect equipment safety when overcurrent occurs during power running.

Overvoltage protection: The allowable grid variation range is 380V±10%. When the grid exceeds the allowable range, the pulse width is automatically adjusted to ensure normal operation of the equipment.

Overheat protection: When the ventilation system is blocked, the internal fault of the ventilation system, the temperature of the fan is too high, the power supply automatically stops working and an alarm signal is issued at the same time.

Phase loss protection: When the grid fault causes the equipment to run out of phase, the system will automatically shut down.

The high frequency switching power supply configurable functions are:

(1), with positive pulse, negative pulse, proportional pulse, interval pulse, counting pulse, timing pulse, program pulse and other functions; (optional)

(2), duty cycle range: 0-100% continuously adjustable, when 100% is pure DC output (optional)

(3), automatic commutation function: that is, the positive pole of the power supply becomes the negative pole, the negative pole becomes the positive pole, and the working time of the forward and reverse can be arbitrarily set (optional)

(4), intelligent: optional standard communication interface RS485 and computer connection to achieve man-machine interface control (optional)

(5), analog signal interface: the user can use 0-5V/10V or 4-20mA signal to control the corresponding parameters of the power supply (optional)

(6), with soft start, timing function, multi-stage control, computer interface, etc. (optional)
