Description

The Europa range of power supplies are a classic high voltage power supply design for laboratory applications. Up to 100kV output voltage is available and both positive and negative polarities can be provided. Extremely accurate output parameters are achieved as can be seen from the specification. The power supply is also well protected against erratic line and load conditions. The reversible section is removable in the form of a drawer accessible from the front of the unit. Two sections – one positive and one negative are exchanged to engage the alternative polarity. Control and monitoring can be via an IEEE interface or by front panel potentiometers.
