DESCRIPTION
The AHVA250V2X20MA is an electronic module for
amplifying an analog input voltage into a high voltage output.
Figure 1 shows its physical photo. It comes with a high voltage
DC-DC converter, which converts the 24V input voltage into a
10 to 250V output voltage. The analog output voltage can
swing almost from 10 to 250V when it is powered by a 24V
power supply. There is three LEDs indicating if the amplifier
works properly.
CAUTION
First, set up the AC power supply and fix it stably and firmly.
Then make sure that the two switches of the high voltage
amplifier are OFF. Connect the 24V DC power supply to the
VPS and PGND of the high voltage amplifier. After the
connection is complete, turn on the low voltage switch and set
the input AC voltage or DC voltage. Then use the output
monitor to check whether the input set voltage is correct.
Finally turn on the high voltage switch.
