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
