8. It has RS485 communication interface and adopts MODBUS-RTU communication protocol.
9. With external analog interface, it can realize external detection of power supply status and control power output.
10. Redundancy technology: The high-power high-voltage power supply system can cut off any one or a group of single machines at any time without affecting the stable operation of the entire power supply system under the condition of configuring redundant machines and equipment. The application of this technology improves certain System stability that cannot be powered off.
11. Protection mode: overvoltage protection, overcurrent protection, overtemperature protection, phase loss protection, short circuit protection, overload protection, input undervoltage and overvoltage protection.
Unique Technology:
1. Multiple anti-fire short-circuit protection to ensure machine reliability
a. The power supply has a current overshoot suppression circuit, which effectively suppresses the current overshoot of several thousand amperes caused by the short circuit of the high-voltage output.
b. The high-voltage output short-circuit will generate instantaneous high-voltage interference through the ground wire and feed it 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 interfered.
c. The short circuit of the power supply will cause the sudden change of the current in the loop. The sensitive current detection circuit detects that the current exceeds the protection set value and starts the current limiting power control circuit within 10 microseconds to ensure that the output current is controlled within the set value.
d. The short circuit of the power supply will cause the high voltage voltage to drop. The voltage drop and flash drop detection circuit detects the ignition short circuit condition of the load at the first time, and starts the protection circuit in time.
2. High-voltage and low-voltage separation design: In order to protect the personal safety of users to the greatest extent, the power supply divides the low-voltage part of the control level and the high-voltage part of the output stage into two chassis designs. The user adjusts the power supply part as a low-voltage cabinet, and the high-voltage part is completely sealed in the high-voltage part. In the casing, and the machine casing is grounded, so as to completely isolate the high-voltage part from the operator.
3. Reliability guarantee of core components: The core components of the power supply use Infineon IGBT modules and Microsemi rectifier modules. The modules have been widely used in various industries in the market, with high operating stability, good versatility and reliability, performance can be guaranteed.
