Product Description:

The multipurpose servo amplifier VT 11037-12a from Bosch Rexroth Indramat offers perfect automation for industrial systems.

This amplifier system works best with input power between 21 V and 35 V, since it can handle 24 VDC with a tolerance range of +40% to -10%. Although certain configurations raise power consumption to 30 VA, the amplifier requires around 25 VA of electricity. The servo amplifier uses 1.2 amps power which meets the needs of different operational applications. The VT 11037-12a uses electronic protection from short circuits for its solenoid and includes a 3.5 A F soldered fuse. The device's 20 kΩ input resistance allows it to interact with various control systems that accept input values between 0 V and ±10 V. The system adjusts output current between I10% and Imax while allowing users to customize I10% and I90% through external potentiometers. The output stage works with a 170 to 200 Hz clock-pulse signal that allows specific module types to adjust their servo systems within specified limits.

The servo amplifier includes 12 terminal screw connections for a simple and effective wiring setup. This unit is also compatible with EN 60715 requirements for TH 35–7.5, which allows it to be firmly fastened to carrier rails for seamless integration. EN 60529 sets IP 20 protection standards for this unit which lets it handle dust and moisture exposure at a limited level. The VT 11037-12a comes with small physical dimensions of 40 x 79 x 85.5 mm and weighs around 0.16 kg. The unit runs for various industrial setups as it operates in a temperature range of 0 to 50 degrees Celsius. It can be purchased at Wake Industrial with a one-year warranty.
