Chroma 52912 PXI Programmable DC Power Supply

The Chroma 52912 PXI Programmable Power Supply is a DC input module designed for precision voltage and current output within PXI-based automated test equipment (ATE) and laboratory environments. It features dual independent and isolated 60W maximum output channels, each programmable from 0 to 48 VDC and up to 2.0 Amps. This power supply is engineered for applications demanding high throughput and measurement accuracy, with capabilities for rapid I/V setting and automatic measurement without processor intervention. Its design emphasizes noise immunity by drawing input power (+56 VDC) via front panel connections, thereby minimizing load on the PXI backplane and maintaining isolation between the backplane logic and power conversion circuitry. For systems without a +56 VDC supply, an optional AC-DC adapter is available. The Chroma 52912 complies with PXI Revision 2.0 and CompactPCI specifications, allowing its use in both PXI and CompactPCI mainframes.
