AC3X220/380V(Y) 15%, 50/60h
1mA~100A (200A Optional)
Standard Wooden Case
Numbers of calibrated energy meter: 16
1.1 The bench accords with the standard of "IEC 60736:1982 Testingequipment for electrical energy meters", "IEC 62053"
1.2 Close-link and ordinary calibration both can be used, ordinary calibration can be used to test single/three phase active and reactiveenergy meter(up to 0.5 class),close-link calibration can be used to testsingle/three phase active and reactive energy meter(up to 1 class).
1.3The bench can test the converted quantity which is caused by negativephase, voltage unbalance, harmonic wave and so on.
1.4 The bench can auto-calibrate starting, no load, basic error and calibration tolerance and 24h deflection.
1.5 Close-link calibration is using insulate current transformer and suitable for close-link energy meter. 1.6 The bench is using the error processor system to calculate the error ofeach energy meter by the sub-error system which can be connected by theinternal RS485.
1.7 The same specification but different constant energy meter can betested at one time.
1.8For the installed pick-up equipment, can offer 3 ranges adjustment. Itis also can be accepted the signal for both round-style energy meter anddigital LED energy meter.
1.9 The bench can choose to operate by keyboard or PC which is convenient. The working status of bench can be seen very clear and easyoperation.
1.10 The bench is using the testing software complied with WINDOWS98/2000/XP which can auto-testing different energy meters.
1.11 The software can realize the data from energy meter for statistics,search and management. It also can connect with on-line management forup load the data.
1.12 The energy meter hanging rack is made by Aluminum compound.The whole device configuration is a reasonable design and nice outfit.
