The PSP System is a single- or three-phase electronic voltage- and current power source used in the testing of electricity meters or other devices.

Principal Characteristics
• Voltage and current ranges:
Voltage: 30 V up to 300 V
Current: 1 mA up to 120 A
• Output power:
Voltage: 800 VA
Current: 1200 VA
• Power efficiency: > 85 %
• Operation of the PSP System over RS 232 C serial line interface

Further Characteristics
The generators create the nominal values for the amplifiers with extremely high accuracy and stability. The amplifiers use the pulsewidth modulation principle, this implies a high working efficiency and therefore very low heat losses. The construction of the PSP System is very compact.
