Product Description:
Bosch Rexroth Indramat manufactured the VT 3026-36. The VT 3026-36 analog amplifier relies on a 24 VDC ±10% power supply to deliver reliable performance in demanding industrial settings. That 10% tolerance is what keeps performance steady-even in the face of small power inconsistencies. To get precise control over output currents, the internal circuitry needs to run on that supply voltage. By using differential voltage principles to provide bidirectional current control, the ±9 V input control voltage sets the signal range for modulating the amplifier's output. That bipolar input range gives you compatibility with a range of analog control systems. And because those systems often drive inductive loads like proportional valves or solenoids, you need accurate voltage-to-current conversion.
The amplifier delivers enough power for industrial actuators with a maximum output current of 800 mA. Efficiency is maintained while doing so. The current limit is controlled by thermal and electromagnetic limitations, which prevent the amplifier from getting saturated or overheating under load. The output stage's switching rate is determined by the 160–180 Hz pulse frequency range. This range maximizes performance for dynamic loads, reduces electromagnetic interference (EMI) and harmonic distortion for systems that are susceptible to noise and makes the amplifier a better fit for those systems. The 2.5 A fuse, with its 5 mm by 20 mm dimensions and standard form factor, offers overcurrent protection. Choosing the right fuse protects downstream critical components by finding that balance between fault protection and operational continuity.
The amplifier's energy conversion efficiency is reflected in its 30 W power demand. The maximum output load of 19.5 Ω shows the lowest impedance it can drive without distortion. But a minimum input load of ≥500 Ω is what guarantees signal integrity by keeping control sources from drawing too much current. In low-signal situations, the 20 mA minimum output (bias) current keeps the solenoid engaged and stops mechanical clatter. Temperature drift (0.5% of Imax per Kelvin) is a key statistic for precision applications it shows the amplifier's thermal stability with little fluctuation in gain throughout operational temperatures. Integrated test points (BU2/BU3) make real-time solenoid current monitoring (20–800 mA) possible. This streamlines diagnostics without affecting operation. The amplifier's small form factor and 0.15 kg construction make it a space-efficient and lightweight addition to modular setups. These criteria work together to balance power supply, thermal management and diagnostic accessibility for strong performance in harsh conditions. That balance means accurate and dependable control in industrial automation.
