Power Consumption

20 VA maximum (90 to 264 Vac)
15 VA maximum (24 Vac/dc)

Power Inrush Current 10A maximum for 4 ms (under operating conditions), reducing to a maximum of 225 mA (90

to 264 Vac operation) or 750 mA (24 Vac/dc operation) after one second.

CAUTION

When applying power to more than one instrument, make sure that sufficient

power is supplied. Otherwise, the instruments may not start up normally due to voltage drop
from the inrush current.

Weight

3 lbs. (1.3 kg)
