|
ELZ-303 Zero Volt Electronic Load
As low as more then Zero
or Zero Volt minimum operation Volt.
As fast as 50A/usec slew rate Response Speed
ELZ-303 Electronic Loads can sink current at
Zero Volt. without an external power supply.
These features can match current trend of faster response and l
lower volt requirements of electronic loads for like current
computer devices.
