HP UPS

HP, HPE and Compaq ranges

Line interactive

Line-interactive technology adds an automatic voltage regulator (AVR): voltage dips and surges are corrected without drawing on the battery, which preserves runtime and battery life. It is the right compromise for demanding workstations, small servers, network racks and CCTV.

On-Line double conversion

On-Line double-conversion technology constantly rectifies and rebuilds the voltage: your equipment is fully isolated from the mains (power cuts, micro-cuts, surges, noise, frequency variations) and the switch to battery happens with no interruption at all. It is the recommended protection for servers, storage, IP telephony, medical or industrial equipment and sites powered by a generator.

HP hybrid

HP "Minimally Switched" hybrid technology works as a very high-efficiency line-interactive UPS (about 94%) while the mains is good and automatically corrects voltage variations; when the power fails, the batteries take over. It suits server racks that need to limit power consumption and heat.

Choosing the right UPS

• Add up the power in watts (W) of the equipment to protect and keep a margin of about 30%: the UPS should not run permanently above 70 to 80% of its rating.
• Check the number and type of outlets (IEC C13, C19, Schuko, terminal block) against your equipment's power cords.
• For longer runtime, choose a model with extendable runtime or an ER version to connect to battery cabinets.
• For automatic and clean shutdown of your servers, use the USB/RS232 port or a network card in the communication slot.

Replacement batteries

UPS batteries wear out even when there are few power cuts: they should be replaced on average every 3 to 5 years. You will find the replacement battery kits for this range in the « HP UPS batteries » section, sorted by generation and with the HP spare battery part number.
