(1) Name: DDVA-1000 manual transformer test instrument.

(2) the environmental groups: belong to GB6587.1-86 "electronic measuring instruments environmental tests program" in group III instrument (can) for use in an outdoor environment.

2.1 input voltage: AC220V + 10%

2.2 work rate: 5KVA

2.3 output current: AC0 ~ 1000A stepless adjustable, panel with digital display current meter

2.4 output voltage: AC0 ~ 1000V

2.5 output waveform: the output current is the standard sine wave, the burr is small, is better than the power system requirements index standard, the ripple coefficient is less than 0.3%. Standard sine wave.

2.6 measurement accuracy: (using the 0.2S material) is actually around 0.3, the current can be smooth and smooth continuous adjustment, the accuracy is higher than 0.5. The current and voltage meter shows the true effective value, high precision, high stability.
