Variable Power Supply/Power Amplifier 4×200 V

The device consists of two identical independent pairs of precision high-voltage power amplifiers. Each pair produces at its two outputs a 10-times amplified sum and difference of the two input voltages. The amplifiers are low-noise and DC accurate. They can drive high capacitive loads without stability problems.

The input voltages can be controlled either manually by precision potentiometers or by external signals. The switching between the manual and external control takes place for each pair of amplifiers independently via a toggle switch.

Typical Applications:

• generation of DC offset voltages for quadrupole mass filters (e.g. in connection with the modular radio-frequency generator)
• control of electrostatic lenses and deflection systems
