Unique technology

1. Multiple anti ignition short circuit protection to ensure the reliability of the machine
(1) the power supply has a current uprush suppression circuit, which can effectively suppress the current uprush of several thousand amperes at the moment of high voltage output short circuit.
(2) when the high-voltage output is short circuited, the instantaneous high-voltage interference will be generated through the ground wire and fed back to the power grid. The special discharge protection circuit of the power supply ensures that other equipment and the power supply itself will not be damaged or disturbed.
(3) short circuit of power supply will cause sudden change of current in the circuit. When the sensitive current detection circuit detects that the current exceeds the set value of protection, it will start the current limiting and power limiting control circuit within 10 microseconds to ensure that the output current is controlled within the set value.
(4) short circuit of power supply will cause high-voltage voltage drop. The voltage drop flash detection circuit detects the ignition short circuit of load at the first time and starts the protection circuit in time.

2. High pressure and low pressure separation design
In order to protect the user's personal safety to the greatest extent, the control level low voltage part and the output level high voltage part are divided into two chassis design. The user's regulating power part is the low voltage cabinet (the maximum voltage is not more than 400V). The high voltage part is completely sealed in the high voltage cabinet, and the machine shell is grounded, so as to completely isolate the high voltage part from the operator.

3. Reliability assurance of core devices
Infineon IGBT module and MICROSEMI rectifier module are adopted as the core components of the power supply. The modules are widely used in various industries in the market, with high operation stability, good versatility and reliability guaranteed.
