• Rated Voltage (Un): 230 / 400V AC (3 ~)
• Operating voltage: 161/279 - 300 / 520V AC (3 ~)
• Insulation capacity:
  - AC voltage: 2KV for 1 minute
  - Voltage pulse load capacity: 6KV - 1.2µS
• Rated current (Ib): 1.5A
• Maximum current (Imax): 6A
• Operating current range: 0.4% Ib-Imax
• Installation power (S1): <0.01VA (per phase, the AV input is short-circuited with a ferrite ring to which the power meter itself is connected). stay within and measure accurately:

R = (2 * ρ * L) / A

Where ρ: specific resistance of the copper wire, A: cross section of the copper wire, l: length of the copper wire.

S2 = I2 * R

Where I: Secondary current of current transformer (5A)

Circuit load: S = S1 + S2, which shows that the power absorbed by the meter (S1) is negligible.

According to the standard MSZ EN60044-1, the rated current of the current converter (Snévl) shall be adapted to the load of the secondary circuit, the value between 25-100% of the rated power shall be: 0.25 * Snévl ≤ S ≤ Snévl
