Variable AC & DC Power Supply

Variable Power Supplies are suitable to use in different applications such as Laboratory, Test & Service that requires wide range of adjustment range for AC or DC voltages

Galvanic isolation is provided with transformer in both AC and DC power supply systems.

Rectifier section is thyristor controlled and inverter section is IGBT controlled which is the common use in ASTOR power supply systems.

ASTOR Adjustable Power Supplies are industrial type, reliable and easy to service.
