Product Description

The VT 2010 S 44 proportional amplifier is designed to control proportional valves in industrial automation systems with maximum efficiency and accuracy. It can handle industrial power situations that fluctuate by operating with a nominal direct current (DC) input voltage of 24 V and a wide tolerance range of 22 V to 35 V DC. The amplifier’s ±8.3% to +45.8% tolerance from the nominal voltage ensures operation even in case of power supply fluctuations and keeps performance at peak. A proper input voltage is essential for the amplifier’s internal circuitry to process the signal and output correctly, to control the proportional valve. A key feature for energy efficiency in industrial applications is the amplifier’s power consumption, which is less than 25 Volt-Amperes (VA). Because of its low power consumption, less heat is generated, and it extends its service life and reduces the need for cooling.

The VT 2010 S 44 also reduces the load on the power supply and protects the system wiring and electrical connections from damage, with a current draw of less than 1 Ampere (A). An additional safety feature is a 2.5 A time-delay fuse. This fuse acts as a safety feature by allowing short inrush currents at startup but cuts the circuit in case of excessive current demand. The two input channels of the VT 2010 S 44 are different. Input 1 has a voltage range of 0 to +9 V and is compatible with a wide range of sensors and control systems. Input 2 has a range of 0 to +10 V and a high input resistance of 100 kΩ and is a differential input that ensures accurate signal transmission by preventing signal loading and improving noise immunity.

In applications where you need fast response times or precise regulated motion, this feature is optimal for valve control. With various clock frequencies and adjustable biasing current to maximize valve performance, the output stage is even more versatile. Additionally, the VT 2010 S 44 has an exact and stable output voltage of ±9 V with a tolerance of ±1%. This controlled voltage is critical for controlling the proportional valve and ensures steady and predictable performance under all conditions. The amplifier is also in Euro-card format and 32-pin male connector making it easy to integrate into common industrial systems. With a storage range of -25 to +85 °C and an operating temperature range of 0 to 50 °C, the device is suitable for all environments. It’s a convenient choice for harsh industrial applications because of its lightweight design making installation and maintenance easier. It weighs only 0.1 kg.
