Va 60V 0.7A (For panel)
15V audio 15V 2.1 A (Audio)
12V 12V 1A (For 60V regulation circuitry)

POWER ON/OFF SEQUENCE
START UP SEQUENCE
- Set CPUGO "High". VCC becomes ready.
- Set PDPGO "High" This product outputs VCEGO "High" after the confirmation of PDPGO
"High" and VCC "Low".
- Input Vcc after the confirmation of VCEGO "High". When Vcc becomes higher than a set
voltage, and Va, Vs are confirmed to lower than set voltages.
- Input Vs and Va after confirmation of VSAGO "High". This product wait 5 sec for Va, Vs more
than set values. If Va and Vs don't rise up to more than set voltages within 5 sec., this product
once shuts down and retries the start up sequence from the beginning.
*Vcego mentioned as Stanby and Vsage mentioned as PDP go on main board.
