The HP 6235A Triple Output Power Supply delivers three adjustable dc output voltages: 0 to +6 V at 1 A, 0 to + 18 V at 0.2 A, and 0 to -18 V at 0.2 A. A single 0 to 36 volt output at 0.2 A can also be obtained by connecting across the + 18 V and -18 V terminals. The controls, meter, and binding posts are conveniently arranged on the front panel. One voltage control simultaneously adjusts the + 18 V and -18 V outputs, which track one another and can be used to power operational amplifiers and other circuits requiring balanced positive and negative voltages. The supply's dual outputs have added versatility with an adjustable tracking ratio control (TRACK) that can set the negative output to a lower voltage than the positive output. Once the trackmg ratio control has established a voltage ratio between the positive and negative outputs, the ratio remains constant as the + 18 V voltage control is adjusted. A third control sets the 0 to +6 V output voltage. The supply is a constant voltage/current limit type with each output voltage continuously adjustable over its range, while the maximum current available is automatically limited to prevent over loading. The power supply's outputs share a common terminal and are isolated from chassis ground so that any output terminal can be grounded if desired . Each output voltage or current can be quickly selected and monitored With the push-button meter switches. Specifications. Output: 0 to +6 V at 1 A, 0 to + 18 V at 0.2 A, 0 to -18 V at 0.2 A.
