Solid State Power Controller

3U OpenVPX Solid-State Power Controller Relay Board. Designed for military and aerospace applications, the 68SR1 offers high-reliability solid-state power switching in demanding environments.

The 68SR1 supports up to three NAI Solid-State Power Controller Relay modules, each offering up to four isolated, high-current, high-voltage output channels. It features a PCIe x1 backplane interface and a factory-configurable Ethernet port supporting either 10/100/1000BASE-T or 1000BASE-X for command and control.

Module options include the SW1 with four normally open low-voltage channels rated at ±100V and 6A continuous per channel, the SW2 with four normally open high-voltage channels rated at ±200V and 4A per channel, and the SW3 with two normally closed low-voltage channels rated at ±100V and 3A per channel.

Additional features include continuous Built-In-Test (BIT), voltage and current monitoring, VITA 46.11 Tier-2 IPMC compatibility, and a rear I/O interface using standard VPX connectors. An RS-232 debug/console port is also included. NAI provides a comprehensive Software Support Kit (SSK) with API libraries, documentation, sample projects, and source code to streamline system integration.
