5.5 Reduced Power Consumption
The Reduced Power Consumption setting will lower the power output of the power supply
recharge unit on the control board, from 75 W to 33 W. This enables the control board to be
supplied with the energy delivered by a voltage transformer if necessary. The Power Supply
Recharge Unit is 80% efficient. This means that the Auxiliary Power supply input must be at
least 93.75 W for the 75 W setting or 41.3 W for the 33 W setting. The 33 W option is hardware
selectable with Jumper JP1019. (see Apx. Figure 4 Standard Actuator Circuit Board and DIP
Switch Settings).

6. POWER CONSIDERATIONS
The control board power supply recharge unit adapts any voltage within the specified range of
the board to maintain 80 V across the capacitors. The following voltage thresholds must be
reached to complete the specified operations:
1. The capacitor voltage threshold for an Open operation is 49 volts.
2. The capacitor voltage threshold for a Close-Open operation is 72.5 volts.
3. The capacitor voltage threshold for an Open-Close-Open operation is 78 volts.
