3. Rated output current: dc180v output current: 5A, instantaneous output current ≥ 30a, duration ≤ 30ms. Dc18v output current: 15A.



4. Output ripple: dc180v: < 0.4% dc18v: < 1%



5. Load adjustment rate: dc180v: < 1% dc18v: < 1%



6. Efficiency: ≥ 82%



7. MTBF ≥ 10000 hours



8. Load characteristics: resistive load



9. Protection function: over and under voltage and over-current protection of input and output



10. Output voltage characteristics: the power supply shall be in the process of soft start. After the power supply is started, the output voltage rises slowly, with rise time ≤ 5S



11. Input and output isolation voltage ≥ 1000V, two output channels are isolated from each other.



12. Output display: independent display of two output voltage and current digital meters



13. Output off and on mode: the power supply is equipped with main control switch and two output control switches; the two output control switches have the interlocking function of local control K0 and remote control K1.



Function introduction of K0 and K1:



Opening process: when the switch is in the off position, there is no output from both channels. When it is turned to the 18V position, it is 18V output. When it is turned to the 200V position, it is 200V output after a delay of 20s (the delay time is adjustable). At this time



18V hold output.



Shutdown process: when the output control switch is turned from 200V position to 18V position, the 200V output is turned off (the shutdown time is less than 20s); when the switch is turned from 18V position to off position, the 18V output is turned off (turned off) after a delay of 20s



The time is adjustable), at this time, 200V continues to maintain no output.



14. Input power-off protection function: during the use of the power supply, after the external AC power is suddenly cut off, the power supply enters the protection, 18V and 200V have no output, and the output control switches K0 and K1 must be turned to the off position



If the opening process is repeated again, the two outputs can work normally.



15. Output regulation: the two output voltages are regulated by the voltage regulation potentiometer installed on the front panel, and the position can be locked.



16. Case specification: 19 inch standard 4U case is selected, and the case depth is 400mm.
