550 Watt 48 Volt AC-DC Front-End

Product Information

The Sigma Series TSG7000 550 Watt 48 Volt AC-DC Front-End is a 1U x 2U hot-swap module which produces 550 watts output at 48VDC.

The TSG7000 550 Watt 48 Volt AC-DC Front-End has automatic load sharing and output ORing diodes so they can be hot-swapped while the system is operating. Module output voltage can be controlled by 0V to +5V analog input.

Green LEDs indicate AC and DC power good. The TSG0000 550 Watt 48 Volt AC-DC Front-End also has control and monitoring features and a +5V standby output. Operating temperature range is -20°C to +70°C.

Companion 19-inch shelves hold up to four modules which can also be operated in a N+1 redundant mode. Single and dual output bus models are available.

THREE YEAR WARRANTY
