0-300V CompactPCI/PXI Power Module

The LV Series CompactPCI/PXI power supply is capable of supplying up to 4 channels of 0 - 300VDC (can be configured as positive or negative output) in a standard 3U chassis. Each channel is computer controlled using an IP Ethernet network and Lab View software. The DC power supply requires an input of 40-70mA depending on the output voltage and has an input impedance of 10K ohm. The modules have less than 10mV peak to peak of ripple and are protected against continuous output short protection.

At the heart of the LV series system; for control and monitor is Quicklogic's 32 bit PCI chip running at 33 MHz, with 14 RAM blocks comprising 32,256 RAM bits and 97 I/O pins. The chip is PCI v2.3 compliant with zero wait states to provide up to 264 MBps transfer rates. It also offers full PCI Configuration Space and flexible target addressing. It supports retry, disconnect with/without data transfer and target abort requested by the user programmable logic. Any number of 32 bit BARs may be configured as either memory or I/O space. The boards also have a CMOS FLASH-based 8-bit microcontroller chip from Microchip which acts as a slave, and assists in controlling and monitoring the feedback voltage.
