Product Description:

The VT-MSPA 1-525-10/V0 valve amplifier, designed by Bosch Rexroth, is a precision-engineered device for operating proportional valves without electrical position feedback. In industrial automation, this amplifier can be used in a number of situations where stable control is needed. Because it works reliably, the amplifier is a strong choice for running systems efficiently.

At 24 V DC, the VT-MSPA 1-525-10/V0 needs an input voltage of 24 V DC, but it can work with any voltage between 21 and 40 V DC. At 24 V DC, it needs about 1.5 A. A differential voltage input with a signal range of 0 to +10 V and an input resistance of 100 kΩ is used for the order value input. The amplifier-clocked PWM power output stage can send out up to 2.5 A of current, and the delay frequency can be changed from 70 to 400 Hz. There is a ramp generator built into the amplifier that lets you change the ramp time for both "up" and "down" movements separately. This allows us to control how fast or slow the movement moves. Users can fine-tune the control features to fit their application needs thanks to the adjustable zero point and sensitivity.

With features like an LED light that shows when it's working and a removable connecting strip, the VT-MSPA 1-525-10/V0 is made to be easy to install and maintain. It's made to fit on a DIN rail and is 35 mm wide, 184 mm tall, and 120 mm deep. It weighs about 0.3 kg and the working temperature range is from -20°C to +70°C, and the storage temperature range is from -25°C to +85°C. For the VT-MSPA 1-525-10/V0 and other products in our range, we offer a one-year replacement guarantee and shipping all over the world.
