Product Introduction
The UCB24_SBO-10WR3 series features an output power of 10W, a 4:1 wide input voltage range, and an efficiency of up to 88%. With a standard isolation voltage of 1500VDC and an operating temperature range of -40°C to +85°C, these converters incorporate protections against input undervoltage as well as output overcurrent, short-circuit, and overvoltage conditions. They are widely used in the communications sector for equipment such as switches, repeaters, smart communication gateways, GPS clock synchronization systems, and DC power supplies for 4G/5G base stations.
