PTC 8320D three phase energy auto-calibration system is a new generation, high precision, energy meter calibration equipment. It uses the advanced technology and components available in update technology, follows the national standard and regulation to develop and design. This bench can be used to test both single / 3 phase energy meter (up to class 0.2%). This bench is using the aluminum compound configuration to form with digital controlled signal source with PWM amplifier, HC3100 standard precision instrument, error processor system and auto-testing software.
PWM amplifier provide high ranges output of voltage and current, the power source efficiency better than 85%.
Auto-range for current / voltage.
Overload protection for voltage / current.
Auto / manual test by keyboard/software on bench.
Come with the 3 phase precision energy meter (0.05% class) with RS232 communication port (Model : HC 3100).
Suitable for different single* / 3 phase electronic / interaction energy meter.
Suitable for 4 phase test.
Calibration software with PC based under Windows 98 / 2000 / XP which the result can be saved, searched, and printed out.
Database provides with statistics, category, information check, management and online function.
* OPTION: For test many single meter in PTC 8320D in one time, must add a single MSVT.
