Stand-alone power supply for e/m experiments, also has special data port for connecting an 850 Universal Interface.
This constant current power supply has a digital readout for the current, which can be tuned from 0 to 3.5 A DC. It also has a 6.3 V AC power supply for heating filaments. A High Current Sensor (PS-2193 or CI-6740) can read the current when using this power supply with interfacing experiments. Both DC and AC outputs are available simultaneously on separate floating output terminals.
