Dual Output Power Supply 2x 0-64 V, 2x 0-2.5 A, 2x 160 W
Option 015 = IEEE 488 Interface
The systemcompatible 8852-64 is a 8850-series dual-output power supply.
Exceptional specifications are achieved with a total output power of 2x160 W
as a result of the classical in-phase control principle.
It deliver voltages up to 2x 64 V and currents 2x 2.5 A. With a resolution of 12 bits in the voltage and current ranges, a simple and convenient user interface, and the excellent specifications, this instrument is suitable for both manual and busbased modes.
A further significant characteristic is the high-resolution measurement of the voltage and current values; these are output on 4-digit LED displays and can be read at a high rate in bus mode.This means that additional measuring instruments are usually superfluous.
The output values are adjusted with a selectable sensitivity using wear-free incremental spinwheels, thus permitting reliable and precise adjustment of the output voltage and current even after many years of service.
Depending on the values set for the voltage and current, the power supply can be operated as a voltage source or a current source depending on the load conditions. All outputs can be connected in parallel or series without problem.
Tracking function:
The automatic tracking mode with dualoutput power supplies means that it is possible to control the output voltage of output 2 as a function (0 % to 100 %) of output 1 with retention of all control properties.
Remote control:
Command syntax in accordance with IEEE 488.2 with command set switchable between compatible TOELLNER commands and SCPI commands.
GPIB interface (option):
Interface connection in accordance with IEEE 488.1; electrically isolated from main outputs. The device address can be set as desired per menu.
Setting rate: approx. 25 settings/s
Measuring rate: approx. 20 measurements/s
RS 232 interface (option):
9-pin D-SUB connector; electrically isolated from the main outputs
Transfer: half-duplex mode, asynchronous; 110 to 19200 baud adjustable permenu.
Setting rate: approx. 20 settings/s
Measuring rate: approx. 15 measurements/s
These modern, proven and exceptionally well equipped power supplies are additionally characterized by supplementary functions such as the saving of 100 instrument settings, the standby circuit for the power outputs, sense and tracking modes.
