Power Supply
Part Number 88983903 88983901 88983902
Nominal supply voltage 110 Va → 240 Va 24 Vc
Voltage supply tolerance -15% / +10% -15% / +20%
Operating limits 93.5 → 264 Va
* Accepts temporary
overvoltage occurring on the
power network
20.4 → 28.8 Vc
* Accepts temporary overvoltage occurring on the power network
AC supply voltage frequency 50/60Hz (-6% / +5%) so 47Hz
→ 53Hz / 57 → 63Hz
N/A
