SB-220-9015-60 Non Standby CATV Power Supply 220Vac 60Hz Input 90Volt/15Amp 1350 Watt Output

Specifications and Documentation


English / Spanish


SB-220-9015-60 non-standby power supply provides conditioned power to signal amplifiers in cable television and broadband distribution systems. The SB-220-9015-60 has screened vents and an output power ON indicator light. The transformer is mounted inside an enclosure and supplies the load with current limited, fully regulated AC power that is free from disturbances caused by spikes, surges and other forms of power line transients. AC power enters the transformer, is converted into a quasi-square wave and regulated at the required output voltage. The power supply output is 90Vac @ 15amps.

The SB-220-9015-60 contains a ferroresonant transformer, resonant capacitor, input breaker, terminal blocks and some electrical components. The transformer is a ferroresonant design, which features constant and fully regulated output voltage, stable performance and high reliability. Primary and secondary windings of the transformer are physically isolated from each other by a steel core which reduces the capacitive coupling of spikes and noise to the secondary winding. A resonant capacitor is connected to the secondary winding of the transformer forming a tank circuit. The advantage of this type of transformer/capacitor design is the ability of the transformer to regulate its output voltage over a wide range of input voltages and output loading. It is advantageous in Broadband TV Network applications as active devices are protected from dangerous voltage fluctuations.
