Single Phase Meter Test Bench SYS12D series
Main features:
1) Adopting large screen LCD display
2) Adopting PWM technology to keep efficiency of amplifier more than 90%
3) Output big power
- Voltage (200VA-1000VA)
- Current (200VA-1800VA)
4) Soft start/stop for output voltage and current
5) Can test current/voltage output faults by itself, and give alarm with protection
6) Automatically switch current range
7) Can test different kind of single phase meter (electronic, induction and reactive meter) at the same time
8) Isolation between voltage loop output, and suitable for testing equipotential energy meter
9) With standard RS485 and RS232 communication interface
10) Can operate by small keyboard on the bench or by PC
11) Can automatically test of creeping, starting, basic error, standard deviation, 24hours various error,
register, and meter constant and so on
12) Convenient operation with software which can be remotely updated
13) Can save test records, equiry and print of test result and also can change format of test data
14) Automatically protection for over-voltage, overload & short circuit
15) Auto short circuit function if meter absence
