SPE SYSTEM

The SPE System is a three-phase electronic voltage- and current power source used in the testing of electricity meters or other devices.
The SPE System is an electronic voltage- and current power source and a meter supply unit for testing electricity meters or for testing other devices which use current or voltage.

Principal Characteristics
• Voltage and current ranges:
Voltage: 30 V up to 300 V
Current: 1 mA up to 120 A
(other values on demand)
• Output power: 300 VA or 600 VA per phase
• Power efficiency: > 85 %
• Operation of the SPE 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 SPE System is very compact.
