Transient voltage recovery shall be 25ms to within +/- 1% of steady state.
5.
Linear load harmonic distortion capability: Output voltage THD of less than 2%
for 100% linear load.
6.
Non-linear load harmonic distortion capability: Output voltage THD of less than
5% for 100% non-linear load when tested using the non-linear load described in
