Low transfer voltage may be adjusted downward to extend brownout range or upward to protect sensitive equipment. High transfer voltage may be adjusted lower to protect sensitive equipment or higher to conserve battery during extended line conditions. Sensitivity to line noise may be adjusted for fuel powered AC generator applications. Self-Tests can automatically be performed every two weeks. This ensures a weakening battery will be detected before it is too late.
Users can opt for weekly testing, testing on startup only, or no automatic self testing.
Alarm may be suppressed or delayed to eliminate nuisance factor. Low battery capacity warning may be moved from 2 minutes up to 10 minutes before battery exhaustion. This allows plenty of time for safe shutdown for UNIX or other complex applications. Minimum battery capacity . When the utility line returns after a shutdown, the UPS can insure that the batteries first recharge to allow for subsequent safe shutdown for file servers and CPUs, but for Telecom or Hub applications, the UPS can be set to reboot immediately.
