- The AN 230 was especially designed as a amplifier to control proportinal valves without position feedback combined with the possibility to get the command signals direct from the amplifier
- reduced power loss, short circuit protected, high dynamic PWM output stages with fast deexcitation
- Variable output current by changing jumpers up to 800, or 1600, or 2500 mA
- Internal adjustable current limiter
- Protected against wrong polarity
- 4 adjustable command signals
- 5 adjustable ramp times ( 4 x command signal ramps, 1 x zero ramp )
- 2 external command signal inputs (4...20mA, ±10V)
- External ramp disable
- Ramp time 0,1s to 10 s
- External enable
- LED indications for power on, ramp off, fail safe, polarity changer +/-, command signal selection H1, H2, H3, H4
- Front panel potentiometer to adjust command signal, ramp time, valve overlap and offset
