Title: T100MD888+ Power supply
Post by: ondulado on November 12, 2003, 02:47:10 AM

What is the minimum voltage to fed the PLC in "12V mode" ?
We have a 100V - 140 VDC source (batteries). How can we feed the PLC ?

When using in 12V configuration, the power supply should be regulated at 12V DC and should not dip below 10.5V at any time.

Your high voltage DC source should be stepped down using a DC-DC converter to 24V DC before connecting to the PLC. At such high voltage there isn't other safe or cheap method of connection.  Check with Vicor for a suitable product:  http://www.vicr.com
