The PS3 three phase power source was designed to provide astable alternating current and voltage source for three phase electricity meter test equipment.

The basic functional components of the PS3 three phase power sources are:

• VIS voltage integrated source
• CIS current integrated source
• ACU control unit

The PS1 single phase power source was designed to provide astable alternating current and voltage source for single phase electricity meter test equipment.

The basic functional components of the PS1 single phase power sources are:

• VIS voltage integrated source
• CIS current integrated source
• ACU control unit

The VIS voltage integrated source was designed to be used as astable alternating voltage source for electricity meter test equipment, and in laboratories. The output voltage is isolated and independent of mains voltage. VIS is available in avariety of configurations depending on the values of output power and output voltage.

The CIS current integrated source was designed to provide astable alternating current source for the electricity meter test equipment, and in laboratories. The output current is isolated and independent from the mains voltage. Different CIS versions are available depending upon the values of output power and output current required.
