AGILENT E3640A 30 W DC POWER SUPPLY 8 V 3 A OR 20 V 1.5 A - PARTS

System output read relatively close to system setting, but the unit has some problems. An attached note says, "Expanded DCV tolerance to +/- 2%" Also, turning the dial knob that would normally adjust the voltage or amperage level didn't always produce a change, sometimes the voltage would increase when it should decrease and vice-versa. It could be very time consuming to actually reach a desired output. This equipment is not operating properly and is offered here for parts only with no warranty.
