MEDIUM VOLTAGE POWER SUPPLIES
Medium VOLTAGE POWER SUPPLIES
Power range up to 70.000W
In principle, the rectified line voltage drives a square wave generator of fixed frequency, whose AC voltage is transformed, rectified and filtered, producing the output voltage. For regulation, the square wave voltage is pulse width modulated. A low residual ripple of the output voltage, together with a high stability, high regulation speed and a low stored energy are all achieved by virtue of the high switching frequency.
Output voltage 125V up to 2000V, continuously adjustable from zero to maximum
Series MCP from 125V to 2kV / 14W to 15kW (Clocked Circuit)
Series MYN from 650V to 2kV / 21kW to 50kW (Thyristor Regulation
A transformer is used to transform the mains supply to high voltage. Either on the primary side or on the secondary side of this transformer a phase controlled thyristor rectifier circuit is fitted. A series LC filter is used to smooth the resulting rectified voltage.
Series MCA from 150V to 3000V / 750W to 9000W (Autoranging)
The NCA/MCA series is an auto ranging power supply design in which the power supplies operate over the full range of their output voltage & current, up to the units maximum rated output power. This results in an operating range which is up to 3-times wider than that of a more conventional power supply. When fitted with the optional computer interface, the MCA/NCA series become versatile programmable power supplies. In principle, the rectified line voltage drives a square wave generator, whose AC voltage is transformed, rectified and filtered, producing the output voltage. For regulation, the square wave voltage is pulse width modulated.
