1 Controller 06 and ELSK 06 durable, reliable analog technique inclusive being, with On/Off switch reverse polarity short circuit-protected calibrate min. or max. current Proportional amplifier module 06. The 06 compact amplifier is used to control the solenoid of a proportional hydraulic valve. The current compensation feature ensures that changes in the coil temperature or fluctuations in the supply voltage do not affect the coil current level. It is integrated in a U-profile and can be secured with one nut on, for example, an instrument panel. The front plate must be separately secured. The proportional amplifier requires a smoothed DC power supply in the range...0 V. The potentiometer is provided with an integral on/off switch.the current at the power output varies linearly with the knob rotation of the potentiometer. With the aid of two trimming potentiometers, both minimum and maximum current values can be set. The amplifier switches off automatically for the duration of any short circuit at the load terminals. Within the amplifier, a quenching diode is connected in parallel with the power output. This protects the output stage against switch-off spikes. The 06 will be supplied in the tabulated housings with numerously options.. Application examples Agricultural and forestry equipment - Fertiliser spreader - Dung spreader - Fodder mix and cast wagon Construction machines - Road rollers - Ground drilling rigs Municipal equipment - Snow and ice cleaning equipment - Sweeper General - Speed and pressure control - Materials handling - Belt and spinner drive - Scraper floor drive.
