Specification:
Voltage: Single phase :100V 220V 380V Three phase three wire:100V 220V 380V 415V
Three phase four wire:100V 220 (380)V 240(415)V.
Above-mentioned can be connected directly. The following should be connected with voltage transformers:380/100V 500/100V 3k/100V 6k/100V 10k/100V 15k/100V 35k/100V
Current:1A,5A The voltage circuit of the meter connected with voltage transformers. Which secondary voltage is 100V,if the secondary voltage is lower than 450V,it also can be connected directly. The current circuit connected is 5A or 1A.Wattmetters and Varmeters with and single phase, which can be used for balance and unbalance burder circuit.
Frequency:50/60Hz
