WARNING!
Operation above +80 °C (+176 °F) is considered abnormal and should be used on a
temporary
1
basis only.
1
Temporary Operation at Abnormal Temperature: Temporary operation is defined as a period of
not more than eight consecutive hours per day, and a total of not more than 15 days in a year.
(This refers to a total of 120 hours in any given year, but no more than 15 occurrences in that one-
year period.)

Regulation:
a)
Static: Steady state regulation is ±0.6% as controlled within the solar converter for any and all
combinations of load from no load to full load, input voltage, and input frequency at a constant
ambient temperature. The associated system controller may provide increased regulation.
b)
Dynamic: For any step load change within the range of 10% to 90% of full load within 50
microseconds, per Telcordia GR-947-CORE, the maximum voltage transient will not exceed 5% of
the initial steady state voltage within 50±10 microseconds. Recovery to within 1% of the initial
steady state voltage does not exceed 1 milliseconds.
