 8. Starting performance: 100 % (normal load).

 9. Repeated start: 2 times / S . 
 10. Constant current and constant voltage performance: static adjustment rate is 100 %, dynamic adjustment rate is 95 %.

 11. Buffering time: 1 ~ 5S .

 12. Symmetry suppression ability >6us .

 13. Intelligent "RE" port negative logic (on-the-ground reset reset; ground-open inverter start).

 14. Given voltage 0 ~ 15V positive logic.

 15. On-board overvoltage, overcurrent indication, voltage limit, current limit indication, frequency sweep indication, intermediate frequency establishment indication, system indication, ±15v indication, restart indication, equipment operation and board working status at a glance.

 16. With constant power, constant current and constant voltage function.

 17. It has the functions of sweeping and constant current repetition.

 18. With frequency band switching function, adapt to various frequency ranges: medium frequency board 300 ~ 2Kz , high frequency board 2KHz ~ 10KHz .
 19. Has a 100 % buffer start function. (The power potentiometer can be turned on at any position).

 20. Inverter symmetry adjustment function can improve the inverter efficiency by 5 to 10 %.

 21. Inverter output pulse amplitude >8v , pulse width >60us , pulse leading edge <1us .

 22. Overcurrent and overvoltage alarm dual output ( 220V-5A )
