These power amplifiers are used to drive the shockless type proportional and flow control valves.
1. Power supply of the outside setting adjuster
When DC input type(AMN-W) power amplifier is used, power supply for the setting adjuster can be provided from this power amplifier, but for only one. However, please use the variable resistor or potentiometre of which impedance is 2 kΩ for the setting adjuster.
2. Supply Switch--
The power amplifier has no power supply switch. As soon as it is connected to a power supply, it comes to be alive. Provide a power switch externally．
