4007 Filed Linear Concentrating Power Supply
1.optical amplifier,fiber equipment
2.Inset anti-thunder device
3.ISO9001,3C ensure high quality
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.
Feature:
1.Exclusive water-proof aluminum-cast shell, anti-radiation, high-efficiency, high-reliability
2.Inset anti-thunder device
3.High-frequency signal inserting loss is low, high isolation, flatness in band is high
4.Inset noise-absorbing surge protection circuit
5.With over-current short-cut circuit, automatic break delay protection circuit, short-cut sound alarm inside
