APPENDIX F – USING A VOLTAGE DOUBLER MODE DRIVE
Figure 1. Main Power Line Connection of the S2xx50 AC Input Voltage Doubler Drive
In the S2xx50 AC input voltage doubler drives, AC line L3 is shorted to the center point of the
two series connected bus capacitors as shown in Figure 1. For voltage doubling, connect
single-phase 120 VAC to J1-9 L1 and J1-7 L3. On the same unit, connecting 240 VAC to J1-9
L1 and J1-8 L2 gives standard single-phase full wave rectification. In both cases, the result is a
320 VDC nominal bus voltage.
Three-phase AC line operation is not possible with the S2xx050 AC input voltage doubler
models. In fact, connection to a three-phase source will damage the drive. Please use the
standard S2xx60 AC input version of the product.
When doubling a 120 VAC line, the drive continuous power specification is derated to about
70% of standard single-phase ratings. The following table gives the power specifications for
120 VAC voltage doubled operation. Refer to the ratings in
Voltage Sag Standard for 240 VAC
single-phase operation.
