Ross Video PS-7558 Universal Power Supply (85-250V)

The Ross Video PS-7558 is a universal power supply engineered for global deployment across AC mains environments. It accepts input voltage from 85 to 250V AC at 50/60 Hz nominal frequency, enabling direct connection to diverse power infrastructures without region-specific variants. The unit integrates over-voltage, over-current, and short-circuit protection to shield connected Ross Video equipment from transient events and fault conditions.

Designed as a dedicated power source for professional broadcast and production systems, the PS-7558 delivers the stable DC output required by Ross Video devices while maintaining operational continuity in variable supply conditions.
