AC Transfer Voltage
During normal operation, the inverter supplies AC power to the applied loads
through the pass-through circuit and simultaneously charges the system batteries.
Whenever the external AC source drops
below
the AC Transfer Voltage (set by
the potentiometer), the inverter switches to battery power in order to maintain the
connected load.
Examples (120 Vac inverter system):
1. The AC Transfer Voltage potentiometer is set to 9:00 o’clock with ODP
disabled. Whenever the incoming AC voltage drops to 40 volts or below, the
inverter will switch to battery power.
2. The AC Transfer Voltage potentiometer is set to 2:00 o’clock with ODP
enabled. Whenever the incoming AC voltage drops to 105 volts or below, the
inverter will switch to battery power.
Important:
ODP does not affect the operation of the AC Transfer Voltage. ODP is
either ON or OFF, depending upon the position of the potentiometer.
Important:
There are 6 settings available for the AC Transfer Voltage for both ODP
OFF and ON as shown in the Table 3-3 below.
Important:
To achieve the fastest transfer time (typically less than 16 ms), set the AC
Transfer Voltage potentiometer near the 2:00 o’clock position (with the ODP enabled); or,
near the 1:00 o’clock position (with the ODP disabled). If a high number of “nuisance
transfers” caused by transients on the AC line occur, adjust the potentiometer from the
maximum position toward the minimum position (i.e., 2 o’clock toward 5 o’clock with
ODP enabled; or 1 o’clock toward 9 o’clock with ODP disabled).
