Summary
BEST POWER SUPPLY adoptes the flexible and stretchable high silicon steel sheet of ring transformer with width capability, high efficiency, noiselessness, net sine wave output and has automatic constant voltage, short-circuit protection and anti-thunder circuit. It’s a desirable power equipment for big and medium-sized CATV system.
Features:
1) Exclusive water-proof aluminum-cast shell
2) Inset anti-thunder device
3) Low inserting loss; high isolation; High flatness in band
4) Inset noise-absorbing surge protection circuit
5) Over-current short-cut circuit,
6) Automatic break delay protection circuit; short-cut sound alarm inside
