Summary:
This is a standards concentrating power supply, having excellent features of water-proof, high-efficiency, high-stability, anti-radiation, heat-loss etc. And high-quality signal-inserting function, low frequency starting point(less than 5MHz), and LED indicator make it more convenient for almost kinds of CATV system, especially for bidirectional CATV system.
Features:
l Exclusive water-proof aluminum-cast shell, anti-radiation, high-efficiency, high-reliability
l Inset anti-thunder device
l High-frequency signal inserting loss is low, high isolation, flatness in band is high
l Inset noise-absorbing surge protection circuit
l With over-current short-cut circuit, automatic break delay protection circuit, short-cut sound alarm inside
