三相程控精密校正源 PTC9300H 二手仪器
Intelligent Power Instrument
The main configuration of PTC 9300H is a computerized 3 phase power source with a built-in precision reference instrument. It sets new industry standards in the field of test & calibration measurements. The PTC 9300H fulfills 4 important functions :
o Reference output readings
o Power transducers' calibrations
o Power meter calibrations
o Test data and setting ranges can be printed out via the parallel port.
PTC 9300H features software control system with multiple micro-processors fully integrated to produce highly stable synthesized 3 phase power outputs and reference readings. All control and selection functions are digitally accessible from the PTC 9300H's front control panel or optionally through a RS-232 port to a remote PC. With the proprietary software, testing functions, results and file management are easily performed. The PTC 9300H's VFD illuminated display screen allows for clear readings and menu command operation.
· Reference Output Readings
The PTC 9300H's 3 phase synthesized source is capable of simulating broad variations of 3 phase 3 wires and 4 wires networks. These 3 phase power outputs with fully adjustable ranges are highly accurate and suitable for laboratory and field applications. This model has the standard accuracies of :
o 0.02% reading for Voltage, Current and Frequency
o 0.05% reading for Watts, Vars, Power Factor, WH, VarH
o 0.015o for Phase Angles
· Power Transducer Calibration Function
In transducer calibration function, the provided analog & digital inputs allow the PTC 9300H to perform comparative error calibrations when testing most types of power transducers.
The calibration process is simple as it uses numeric symbol codes in identifying the transducer type, input and output range. A list of commonly used calibration ranges are preprogrammed into PTC 9300H. Some of non-programmed test can be accomplished into test by using programmable input & output ratio function and correcting input and output relationships to meet requirements.
Calibration is further simplified with the option to perform all tests in either fully automatic or manual steps mode. A high degree of refined calibration is achievable as all test modes are pided into 7 or 11 test points (steps).
· Power Meter Calibration Function
Besides transducer calibration, PTC 9300H is also designed for power meter testing & calibration. Similarly, it adopts the simple numeric symbol codes for defining the test meter types, input range and . Additionally, The power meter calibration function features :
o Direct error detection of the test meter
o Direct range readings with PT / CT ratio selection
