Voltage 85V to 250V 0.1V ±1% THD < 2%
Frequency 45Hz to 65Hz 0.01Hz ± 0.1 Hz -

Power Factor PF (0 ~ 1) 0.001PF ± 0.04 -
NOTE 1: The maximum output power is approximately 100VA for duration of 2 minutes; therefore the output current
may be varied according to the voltage value. For example, after setting the voltage to
≧
150V, the maximum output
current will be 0.75A.
NOTE 2: The output duration can be longer than 2 minutes if the output is less than 100VA. If the output is less than
25VA then the output can run continuously.
Rear Panel Specifications (Input power is looped through to the REAR output)
