Note:
1. Factory setting is 208V. Commissioning engineers can set to 200V.
2. Factory setting is 50Hz. Commissioning engineers can set to 60Hz.
3. EN50091-3(1.4.58) crest ratio is 3: 1.
4. IEC62040-3/EN50091-3 including 0％～100％～0％ load transient, the recovery time is half
circle to within 5% of stable output voltage.
