PM0650
Floating 6-Ch Integrated Power Source

Scheduled Release 3Q04
Printable Version

The PM0650 is a sophisticated 6-channel power source providing 3 different supply requirements:

* 2 channels capable of continuous 50V/2A
* 2 channels capable of pulse 50V/2A
* 2 channels capable of continuous 50V/50mA

The pulse channels provide voltage pulses with duration control 10us to 100ms, and measures current. The combination of capabilities provides a versatile solution on fulfilling the wide range of requirements on testing a device. The PM0650 may be floated up to ±1500V to facilitate HV isolation test of devices where outputs may be connected directly to line voltages.

The PM0650 operates with an onboard controller, which relieves the system CPU of performing many functions necessary for module operation. The result is higher efficiency of CPU and faster execution of the module commands. All measurements use the “Zero Time Average” (ZTA) circuit (patent pending) that allows for a measurement time of less then 250 us to the full 16-bit resolution. ZTA enables the PM0650 to obtain the repeatability of using 20 to 50 measurements and averaging the results, with a single measurement.

The PM0650 implements a calibration method called Hardware Error Correction (HEC) (patent pending). This method performs a full calibration, correcting errors for every code, as opposed to the more traditional two-point calibration of offset and gain correction. This method uses no CPU time, which accelerates the forcing and measurement functions.
