PG-X2
There are 5 V and 12 V PG power supplies.
Check the PG power supply specifications before connecting.
The maximum response frequency is 300 kHz.
Use the following equation to calculate the output frequency of the PG (f
PG
).
A separate power supply is needed if the PG power supply requirements are greater than 200 mA. Use a
backup capacitor or some other type of back up power to handle any concerns with momentary loss of power,
