Overview
Specifications
NOTE During AC line failure conditions, the PowerTrust UPS should not be
operated from small portable generators, small portable motor generators, or
other poorly regulated or distorted AC voltage sources. Use only high quality
AC sources to supply input power to the UPS to ensure continued protection
of your equipment.
Voltage and Frequency
Voltage
When the AC input voltage drops below or rises above a specific value, the UPS
automatically provides power to the connected equipment from its batteries. These voltage
values are called transfer points. The UPS input voltage and frequency transfer points for
the UPS are documented in Table 1-2 and shown in Figure 1-8 and Figure 1-9.
At power-on, the auto-ranging feature of the UPS measures the incoming AC voltage level
and frequency to determine the correct operational mode.
1. 50A max branch circuit overcurrent protection.
2. Outside these ranges the A3589A UPS may not turn on, or it may switch to
on-battery operation if it is already on. Frequency range, specified above.
3. For input frequencies within the range specified in "Normal Operating Fre-
quency Range."
4. The first number applies when the UPS operates within 50
±
3 Hz before the
input power fails (or violates the operating limits). The second number applies
when the UPS operates within 60
±
3 Hz before the input power fails (or violates
the operating limits).
5. For loads with crest factors of 3.0 or less.
6. For loads with power factors of 1.0 (resistive or PFC).
7. Independent of load power factor or crest factor.
8. For purely resistive load.
9. Shutdown delay is implemented by PFC firmware. Delay decreases in inverse
relation to the degree of output overload. In addition, UPS Outputs 1 through 4
are protected by corresponding Output circuit breakers 1 through 4.
10.Battery life is severely shortened if temperature exceeds 25
°
C (77
°
F) for
extended periods of time.
