3KVA Power Supply with User Defined Voltages
The VPS-LA-3KVA is a stand alone AC to DC power supply that features user defined input and bus voltages for maximum flexibility.
VPS-LA-3KVA-xxxVAC-yyyVDC
| xxx | Input AC voltage, phase to phase. For example: input power 220VAC to neutral, xxx should be 380VAC |
| yyy | Output bipolar DC bus voltage. For example: yyy=260 indicates output DC bus voltage is +/- 130V |
