SB-UL6090-15PS Non Standby CATV Power Supply UL Listed (Indoor or Outdoor Use) 120Vac 60Hz Input 60Volt/15Amp or 90Volt/10Amp 900 Watt Output

Specifications and Documentation


English / Spanish


SB-UL6090-15PS non-standby UL Listed power supply providing conditioned power to signal amplifiers in cable television and broadband distribution systems. The UL Listed transformer is mounted inside a UL listed Rainproof type 3R enclosure (for Indoor or outdoor use) 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 entering the transformer is converted into a quasi-square wave and regulated at the required output voltage. The power supply output is either 60Vac or 90Vac field selectable,” Not to be used simultaneously.” Shipped in 60VAC model.

The SB-UL6090-15PS contains a Ferro resonant transformer, resonant capacitor, input breaker, terminal blocks and various electrical parts. All components are individually UL Listed. The transformer is a Ferro resonant 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.
