• Portable single-phase precision power source with inset meter standard.
• Separate output between current and voltage. With multiplex PT for voltage,
  the equipment can test meters simultaneously.
• High accuracy at output current/voltage/phase state.
• Equipped with RS232C interface
  for external connection.
• Using software and reference meter,
  automatic testing can be realized.

It is a portable power source of program control for site production line. With the technology of PWM pulse width modulation amplifier, the equipment offers the features of large output power, high stability, low power consumption, high efficiency and small size. Providing stable and ideal operation condition for measurement of 50Hz operating frequency, the equipment fits all kinds of energy meters.
