Adjustable bipolar highly stable power supplies

A line of highly stable adjustable bipolar base power supplies of two series: low-voltage ± 10, ± 100, ± 300, ± 600 V and high-voltage ± 1000, ± 1500, ± 3000, ± 5000 V. The necessary parameters of power supplies are determined on the basis of modern requirements for power supplies that are part of various analytical instruments and complexes. These parameters include: bipolarity, high stability no worse than 5·10-6, isolated electrical output, absence of mechanical adjustments - control from a personal computer, calibration of blocks not more than 2 times a month. To control power supply units, switching devices for 24 and 48 channels for power supply systems have been designed, and for a single power supply unit, a single-channel interface unit. Complete with switching devices, the software implements: setting the operating voltage independently for each power supply unit, displaying the set and measured voltage in the power supply, simultaneous activation of the required power supplies, calibration and adjustment of the units.
