VT-VRPA1-50-12
The Bosch Rexroth Indramat VT-VRPA1-50-12 amplifier from the VT-VRPA Electric Amplifiers series is an electro-hydraulic control unit designed for proportional control/relief valve applications. It delivers precise flow with a controlled linear response, supports a maximum working pressure of 6000 psi, and accommodates a nominal size of 50. Operating reliably across a temperature range of -54°C to 538°C, it uses advanced elastomer/PTFE seals and accepts a rated control voltage of 12 VDC. Threaded or flanged connections facilitate installation with port interfaces from 3 mm to 32 mm. Robust features include reverse polarity protection, adjustable ramp times via jumpers, integrated position summator, and a built-in 2.5 A T fuse for circuit safety. The unit’s zero point adjustment spans from –5% to +30%, and it requires LiYCY cables for solenoid connections up to 50 m. Engineered for industrial automation, it ensures high performance and reliable electrical position feedback.
