5-7-3 APS/APS Pro (LV Power & HV Power)
NOTE: HVL+ and HVL- are not available for APS PRO.
DC Powers are supplied by APS and source of all assys in nest and nest fan, etc. To turn on the APS,
the live power is needed as a standby power. This live power is generated from APS when the APS
receive the AC input from the TRANSBOX. When the LP(live power) is supplied to the L1SYSCON and
system momentary switch is pushed on, L1SYSCON make the LV_ON signal level into low to turn on
the APS. After turning on the APS, the ACPC in TRANSBOX assy change the relay path on itself to
supply stable AC power by using of D12V from APS.
DC Output Capacity:
• +D5VLP, 0.42A rms
• +D5V, 6.5A rms
• +D3.3V, 6.48A rms
• +D12V, 3.36A rms
• +D12VFAN, 0.94A rms
• +A6V, 7.92A rms
• -A6V, 1.52A rms
• +A12V, 1.26A rms
• -A12V, 0.6A rms
APS supplies High Voltage power to activate high voltage transmit pulse and static supply bias voltage
on high voltage mux and probe. When L1SYSCON makes the HV_STOP signal to low, the APS
generates the HV module in APS. The SHV supplies +/-80V to the system constantly and the THVH
and THVL supplies 0~+/- 60V individually.
SYSCONPM(SYSCONCM) control the level of THVH and THVL through the IIC interface.
HV Output Capacity:
• +SHV, +80V, 0.05A rms
• - SHV, -80V, 0.05A rms
• +THVH, 0V~+60V, 0.5A rms
• - THVH, -60V~0V, 0.5A rms
• +THVL, 0V~+60V, 0.5A rms
• - THVL, -60V~0V, 0.5A rms
