465...800Vdc ( 380-500 Vac)
640...1100Vdc ( 525-690 Vac)
The waviness of the inverter supply voltage, which is
formed in rectification of the electric network's
alternating voltage in basic frequency, must be less
than 50V peak-to-peak.

IH: Ambient tempe40 °C (104 °F),
overloadability 1.5 x IH (1 min./10 min.).
- 50 °C (104 - 122°F), the ambient
temperatures use derating factor IH*1.5%/1 °C (°F).
55 °C (122 - 131°F), the ambient
temperatures use derating factor IH*2.5% /1 °C (°F).
