Product Description:
The VT-VARAP1-537-20/V0 is electric amplifier that was made by Bosch Rexroth Indramat. For size 10 valves, the amplifier can handle solenoid outputs of up to 60 VA and 3.7 A that makes it compatible with 4WRPH10 valves. The 20-29 (2X) component series includes this amplifier that typically consumes 55 W of power.
With a differential amplifier input for Q control that can accept ±10 V and a p control input that can operate from 0 to 10 V, the VT-VARAP1-537-20/V0 electric amplifier command value input system is equipped. The sensor's power source is z6 and runs at +15V / 35 mA. The solenoid receives 3.7 A from the output stage. To activate the pressure controller, the external inquiry requires 24V and a maximum current of 0.1 A at z24. To guarantee steady system operation, the amplifier has a frequency limit of 30 Hz or less. The maximum current draw is 2.7 A. With a full-wave rectifier, the rectified AC voltage can be anywhere from 21 to 28 volts, and the voltage range of the batteries can be anywhere from 21 to 40 volts. The amplifier's dependability for applications requiring accuracy in industrial automation is enhanced by these qualities.
An integrated timed current controller improves efficiency by controlling the output of the solenoid in the amplifier. The amplifier has a timed current controller that allows it to run at a maximum solenoid output of 3.7 A and requires a nominal 24 VDC supply voltage. The amplifier has a reference signal for the main stage that gives the control system immediate feedback. Stable functioning in demanding applications requiring strong dynamic response is ensured by the design of VT-VARAP1-537-20/V0 amplifier.
Frequently Asked Questions about VT-VARAP1-537-20/V0:
Q: Does VT-VARAP1-537-20/V0 support multiple pressure sensor inputs?
A: Yes, the amplifier supports 4-20 mA, 0-10 V, and 1-6 V inputs. These inputs enhance compatibility with various pressure sensors for accurate control.
Q: Do the command value inputs of VT-VARAP1-537-20/V0 vary?
A: Yes, the Q command value input operates at ±10 V, while the p command value input ranges from 0 to 10 V. This enables flexible signal processing.
Q: Why does VT-VARAP1-537-20/V0 use a ±15V transducer supply?
A: The ±15V transducer supply ensures stable electrical position feedback. It enhances accuracy and reliability in high-response valve control applications.
Q: How does VT-VARAP1-537-20/V0 achieve precise closed-loop control?
A: The amplifier uses a p/Q closed-loop system with differential amplification. This allows precise pressure and flow regulation for hydraulic control applications.
Q: Why does VT-VARAP1-537-20/V0 have a limit frequency of ≤30 Hz?
A: The limit frequency of ≤30 Hz prevents unwanted oscillations. It stabilizes the system response for better control and smoother operation.
