Source of supply

Uninterruptible Power Supplies Designed to meet or exceed the safety standards established by UL, CSA, CE and VDE. The Alpha CFR UPS is one of the safest, most reliable and versatile Uninterruptible Power Systems available. Input current waveform correction eliminates overheating effects of non-linear load current harmonics. Input power-factor correction brings low power-factor loads to near unity, reducing electric utility costs. The CFR Series sets the standard for the effective powering of non-linear or actively regulated loads, while providing superior surge and noise rejection. Power ratings of 600VA to 15KVA available.

Complete input to output isolation provides the industry’s best surge and
lightning protection.
Highest efficiency and MTBF in the UPS industry.
The CFR’s microprocessor design provides efficiency ratings up to 92%.
Features a RS-232 communication port and is SNMP and modem compatible.
Optional External Battery Packs greatly extend available backup time.
36 month limited warranty.
