17IPS55 board includes AC/DC a full bridge diode rectifier,
a DC/DC low power
Flyback converter for
stand-by voltage +5V and half-bridge resonant converter for +24V & +12V and
two DC/DC Boost Converter stages having 24V input voltages. Total input power is 250W at
100Vac input voltage.
Power board has low power consumption for stand-by mode.
The only voltage is supplied at stand-by condition is 5V.
For low power consumption in standby mode, +24V and +12V
outputs is not activated.
The only voltage in standby mode is 5V and allowed
maximum current is 20mA in this condition.
CN8-INPUT.
