The power source PPS is a portable source of single-phase signals for checking tests and adjustment of all types of electricity meters. This source can supply electricity meter for data reading, adjustment and programming. Along with the working standard WS can be checked precision of meters at place of installation spot.
Properties
- Rough and fine smooth current adjustment;
- Output current indication;
- Galvanic isolation of voltage and current outputs;
- Zero values of the output voltage and current with the first switch-on;
- Voltage outputs U and U1/2 create galvanically isolated line voltage;
- Adjustable phase shif;
- Temperature and current protection of the power stages;
- Single phase power supply.
