Power Supply
The STS2/PDU is supplied with redundant power supplies that are designed to operate from a voltage
range of 200V to 600V. The unit is set at the factory to match the nameplate voltage. Field adjust-
ments are not necessary. If the unit needs to operate at a voltage other than what is listed on the
nameplate, contact Liebert Global Services or your local Liebert representative. Table 6 provides
transformer tap information.
