Electronic DC Load
The ELA 250 Series loads are electronically regulated DC loads with power up to 250Watt. They are designed with the latest MOStechnology and a DC load range starting at 0.35VDC up to 160VDC.Anyywhere DC loads are needed as a stand alone type or integrated via interface in system applications, the ELA 250series offers intelligent features such as:Minimum load voltage 0.35VDC / Load ON/OFF / Remote Control Port (RCP) with additional 0.15VDC voltage to supplyexternal components / Local-Lockout / U- and I-Monitor outputs buffered / Load-On-Relay at Power-Up / etc
