HP 750W Flex Slot Battery Backup Power Supply

The HP 738024-B21 is a 750-watt Flex Slot battery backup power module designed for hot-pluggable, tool-less installation into compatible HP ProLiant Gen10 Performance Servers. It operates on an input voltage range of 230 to 380 volts and provides integrated battery backup functionality to help reduce data center outages during power interruptions. This unit serves as a direct replacement or spare part identified by option numbers 754380-001 and 751830-001.

Suited for HP ProLiant Gen10 server deployments

This module suits administrators managing HP ProLiant Gen10 Performance Servers that accept Flex Slot power supplies and require hot-swap capability with built-in battery backup. It is not suitable for servers using different form factors or input voltage ranges, nor for environments that do not support 230 to 380 volt supply infrastructure. Buyers needing higher wattage output or alternative connector types should look at other compatible power modules.

750W maximum power with 230 to 380V input

The single specification that determines compatibility is the 750-watt maximum power rating combined with the 230 to 380-volt AC input requirement. The server chassis must support the Flex Slot physical design and this specific voltage range for the module to function correctly. Verify the server power bay configuration and facility voltage before purchase to ensure proper operation.

商品問答

Should I choose the 738024-B21 retail part or the 754380-001 option part for my Gen10 server?

Both part numbers refer to the same 750 W Flex Slot battery backup module; the 738024-B21 is the retail SKU while 754380-001 and 751830-001 are option SKUs used in configure-to-order builds.

What does the 750 W rating deliver once the unit is installed in a ProLiant Gen10 chassis?

It provides up to 750 watts of continuous output to the server backplane, with battery-backed ride-through that keeps the power rails live during brief mains interruptions.

The input range shows 230 to 380 V — what does that cap in practice?

The module accepts single-phase AC from 230 V up to 380 V, so it operates on standard 230 V circuits and also on higher-voltage three-phase distribution without a separate transformer.
