Product Description:

The VT-MSPA2-21/A5/000/000 is an industrial valve amplifier built by Bosch Rexroth to provide a reliable control of pump controls and valves. This amplifier works without any feedback system; instead, it contains special push buttons designed for valve optimization during its operation. The characteristic curve of the valves is also stored in the device. This product has a small and compact housing design that makes it easy for operators to handle and install it; there are also about eight integrated LEDs on this housing to provide real-time information about the current status of the amplifier. The VT-MSPA2-21/A5/000/000 is built to be resistant to output short circuiting; it also comes with a curve generator that operators can adjust to meet the operation and technical requirements of the hydraulic system it is to be used with.

The VT-MSPA2-21/A5/000/000 valve amplifier is able to accurately control the solenoid current by measuring it, comparing it with the standard value, and making up for the difference in real-time. Also, the ramp generator in this servo amplifier is flexible enough to allow customers to choose a single time for all ramps or a different time for each ramp. There is an expert setup where the operator can decide the different ramp times. The curve generator in the VT-MSPA2-21/A5/000/000 does not affect the ramp time of this amplifier in any way.

The VT-MSPA2-21/A5/000/000 valve amplifier is a 2 component series, it operates with a nominal voltage of 24 volts, although deviations of up to 40 per cent increase and 20 per cent decrease are allowed in the nominal voltage. The minimum power consumed by this amplifier during its operation is about 48 watts, while its maximum current consumption is determined to be less than 2 amperes.

Frequently Asked Questions about VT-MSPA2-21/A5/000/000:

Q: What is the VT-MSPA2-21/A5/000/000 designed for?

A: The VT-MSPA2-21/A5/000/000 is a valve amplifier built by Bosch Rexroth for controlling proportional valves without electrical position feedback.

Q: Is there a ramp generator on this device?

A: Yes. The VT-MSPA2-21/A5/000/000 features a ramp generator that can be separately adjusted up and down by the operator.

Q: Does the VT-MSPA2-21/A5/000/000 feature any protection against short circuiting?

A: Yes. The output interface of this amplifier is short circuit proof.

Q: How can the operation status on the VT-MSPA2-21/A5/000/000 be monitored?

A: The VT-MSPA2-21/A5/000/000 contains several LED displays that communicate operation status on the amplifier in real time.

Q: How does the VT-MSPA2-21/A5/000/000 carry out current control?

A: The solenoid current in the amplifier is recorded and compared to the command value in the current controller. The amplifier them compensates for the difference in the two values.
