Power versus Output Frequency Rating Chart
The following thermal ratings apply to models 1020, 1030 and 1040 as a function of
load and programmed output frequency at an ambient temperature of 25°C. This
derating is caused by heat build-up in the output transformer.
Output load ratings expressed as restive load reflecting % of full load for frequency
ranges at which the power source can operate continuously are as follows:
45Hz ~ 100Hz
90% resistive load
< 200Hz
77% resistive load
< 300Hz
65% resistor load
< 400Hz
52% resistor load
< 500Hz
40% resistor load
At an output frequency of 500Hz and output power into 70% resistor load, the power
source can operate for a period of 15 minutes then instrument output will shut down
because output transformer is too hot.
