Product Description:

The VT-VSPA 1-525-10/V0/RPT is a Proportional Amplifier that exists as a product of Bosch Rexroth to be used in industrial automation. The component works with a standard 24 V DC power feed. The voltage compatible with battery power extends from 21 to 40 V but each model has a peak power consumption rate of 35 VA.

The peak current power of the VT-VSPA 1-525-10/V0/RPT amplifier reaches 2.5 A when operating at size 10. Full load of requires Size 10 controllers to use a power consumption of 60 VA. A size 6 amplifier works with a 1.5A current during its maximum operation. An integral feature of the amplifier protects both input terminals and output terminals from short circuits. The output stage includes a timed controller which controls how the switching operates. The VT-VSPA 1-525-10/V0/RPT amplifier requires 50 milliseconds for valve setting when using a 100-signal step. Input signal types include b10, z10, z16, and z18. The amplifier accepts differential signals to improve system accuracy. Users can adjust the ramp time from 0.05 to 5 seconds using the device. The plug-in connection depends on a DIN 41612 – F32 connector system. The device input supports electricity that ranges from 6 to 40 V DC with 10 V DC as its nominal voltage value.

The operating parameters of VT-VSPA 1-525-10/V0/RPT amplifier extend from 0 to +70 °C of ambient temperature. The device maintains its performance after storage between -20 °C to +70 °C. Operation of the amplifier maintains valve hysteresis at a level of less than 4 percent. The device provides z20 input for a monitor signal ramp functionality. The monitoring function requires inputs from 0 to 10 V controller level. Users can activate an external ramp shutdown using b20 as the control input. The complete unit weight amounts to 0.32 kg.
