Mr HàVAR95: Var Transducer Vietnam
| Voltage Input 110 VAC, 220 VAC, 380 VAC
- Current Input 1 A, 5 A - Analog Output 4-20 mA, 0-5 VDC |
The Var Transducers VAR95 are used to convert single or three phase unbalance load reactive power into a proportional load independent DC. output. Based fully electronic Time-Division Multiplication measuring principle, the reactive power of a network with any power factor range are linearly produced by Var Transducers output.

Equation to calculated measuring range
Measuring range = Calibration var x PT ratio x CT ratio
Example 3phase,3wire, PT 220V/110V, CT 250/5A, Calibration var = 1000W
Measuring range = 1000 x (220/110) x (250/5) = 100 Kvar.
