v Frequency (in backup mode): 60 Hz ±3 Hz for line frequency > 55 Hz; 50 Hz ±3
Hz for line frequency < 55 Hz (output waveform is a stepped sine wave
approximation)
v Transfer time: less than 8 ms typical, 10 ms maximum, AC to battery
The characteristics of the batteries are as follows:
v The battery is replaceable by persons with typical PC hardware upgrade skills.
v Battery recharge time is typically 8 hours, with a maximum of 16 hours for a fully
depleted battery.
v Battery type is a 12 V, 5 AH, sealed, leakproof, maintenance-free lead-acid type.
Battery life
With a new, fully charged battery, the uninterruptible power supply is capable of
delivering full output for 2.5 minutes. Typical POS configurations require much less
power. A typical system unit with an liquid crystal display (LCD) operator display can
last 15 minutes with a new, fully charged battery, depending on print activity, and it
can last 60 minutes if the terminal is in standby mode. The battery charge capacity
decreases over time and this decrease is accelerated by heavy usage. Regular
deep discharges of the battery can dramatically reduce its useful service life. The
useful life of a battery in a typical environment is 1 to 3 years.
Input voltage
The uninterruptible power supply option cannot sense low-line versus high-line
voltages. Separate units are designed for low-line and high-line voltages, which
cannot be converted between high-line and low-line voltage.
Attention: Damage to the uninterruptible power supply will occur if incorrect line
voltage is applied to the unit.
