3) Power Dissipated:30W (max)

4) Voltage Sensing:170-270/380-415/440-480V

 (three or single phase sensing)

5) Output Voltage(DC): 80V (max, continuous)

6) Output Current(DC):8A (max, continuous)

7) Output Current(DC):15A (max 1 minute forcing)

8) Regulation Accuracy: +/-0.5% steady state conditions, for rated voltage and PF

9) Voltage Drift: +/-0.5% of voltage change for 50°C T amb change

10) Response Time: 1 cycle (12ms-16.6ms)

11) Operating Temperature: -30°C- +70°C

12) exciter Field Resistance: 3.5Ω (min)-20Ω (max)
