The ZVE Power Source was specially designed for use as an electro technical current and voltage generator in Meter Test Systems and also in other automatic test systems.
The power source creates the current and voltages - the phantom load - required for measuring the meters. The network as generated by the ZVE system is completely distinct from that of the mains power supply. The generated values are, consequently, practically independent of the quality of the public power supply.
The cabinet is equipped with the following components
• Control unit STE 10
• One up to three Voltage power sources PSU 10
• One up to three Current power sources PSI 10
• Digital electronic reference meter SRS 121.3 or other types (Option)
 
In each power source there is a digital generator and an amplifier to generate the sine waves for current and voltage
