The VT-VSPA1K-1-1X is a sophisticated analog amplifier from Bosch's component series 1X. Equipped with a 16-pole terminal strip, it excludes a front plate but includes an LED display on its front panel. The amplifier comes with specific DIL switches located on the printed circuit board (PCB), designed for set up ahead of commissioning. Offering dimensions of 128 x 20.3 millimeters and a 24 volts DC nominal input, the VT-VSPA1K-1-1X power requirement ranges between 22 to 35 volts DC with a maximum power usage of 50 VA. The maximum current draw is 1.8 amps, protected by a 2.5-amp slow-blow safety fuse. The device features a flexible differential input which can switch between voltage and current, while an additional input accepts 0 to +9 volts DC. Featuring a configurable ramp generator, the amplifier allows for quick adjustments of downward and upward ramp times to approximately 30 milliseconds. The amplifier functions between an ambient temperature of 32 and 122 degrees Fahrenheit, and can be safely stored at -4 to 185 degrees Fahrenheit. The VT-VSPA1K-1-1X weighs approximately 0.1 kilograms and must be installed with adequate spacing from sources of EMI and power lines to ensure optimal performance.
