  
Our Model 3012A is a universal DC power source with high
volt-ampere capability. Its broad range of operating features
and performance make it well suited for on-line production
testing, electronic system development, component burn-in and a
variety of lab-type applications. Educational users will also
appreciate this cost-effective unit. The 3012A is designed to operate in
a constant voltage or constant current mode. Constant
voltage operation is maintained for loads drawing less than the
preset current level. If the load current should exceed the current
control setting, the power supply will automatically deliver a fully
regulated current to the load. Additional features include
easy-to-read panel meters to simultaneously monitor V&A outputs,
system flexibility, low output drift and heavy-duty, 5-way binding posts.
