To insure proper operation, AC input should be within the pre-specified range. A wrong input will cause the supply unit operating
improperly, losing PFC function or even damaging the unit in a worst case scenario.

Built-in inrush current limiting circuit
PHP-3500-24 : 3480W (24V / 145A)
PHP-3500-48 : 3504W (48V / 73A)
◎
If adding an external switch (a relay/ a circuit breaker) at the input side is required, choose switches that are able to withstand
◎
Since the inrush current limiting circuit mainly consists of a NTC thermistor and a relay, inrush current will be much higher than the

Power Factor Correction (PFC)
◎
Built-in active power factor correction (PFC) function, power factor (PF) will be 0.95 or better when input voltage is in a range of
90-230Vac and operated at full load condition. PF will be less than 0.95 if the output is not at full load or the input voltage is higher
than 230Vac.
