Powering Communications and Technology OBS SERIES 25 WATT FEATURES • Industry standard package • • 24 and 48V input versions • • 25W output power • 100°C baseplate operation • • TECHNICAL SPECIFICATIONS Input Voltage Range 24 VDC Nominal 48 VDC Nominal Reflected Ripple Input Reverse Voltage Protection DESCRIPTION OBS single output DC/DC converters provide up to 25 Watts of output power in an industry standard package and footprint. The OBS units feature excellent efficiency, sixsided shielding, and fixed switching frequency. With 100°C case operation, the OBS converters are especially suited to telecom, networking, and industrial applications. These units are 100% surface-mount construction and fully compatible with production board washing processes.
