2.3.3. 40/80 VDC Power Transformers
The TV0.3-56 power transformer is an optional accessory for the Ndrive HP. The
transformer allows the generation of 56 VAC from a 115 VAC and 230 VAC source
respectively. When rectified by the Ndrive HP, 56 VAC yields an 80 VDC power bus.
The TV0.3-28 power transformer is an optional accessory available for the Ndrive HP.
This transformer allows for the generation of 28 VAC from a 115 VAC or 230 VAC
source, respectively. When rectified by the Ndrive, 28 VAC yields a 40 VDC power bus.
The following three figures illustrate the six combinations available for both AC input
voltages and all three DC bus voltages, as well as the use of the -AUXPWR option.
A TM3 and TM5 transformer package is also available to power up to four Ndrives,
providing 300 or 500 watts of power.
