îš„PG-D2/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 computer the output frequency of the PG (f
PG
).
A separate power supply is required if the PG power supply capacity is greater than 200 mA. (If momentary
power loss must be handled, use a backup capacitor or other method.)
