Разъемный переключающий усилитель с широтно-импульсной модуляцией (ШИМ) VT-SSBA1-PWM

Description Component series 1X Features Fast switching: Control of hydraulic on/off valves with 12 V solenoids Energy savings: Power reduction in the control of hydraulic on/off valves with 24 V solenoids Reduction in the coil temperature of at least 30°K with 100% duty cycle (with energy savings) Suitable for the control of on/off valves of the type WE 6 and WE 10 with 12 V and/or 24 V direct current solenoids with the control spools described in the data sheet. For valves with connector K4 (according to EN 175301-803) Potted-in cable with open end 3-conductor connection, power supply and release separated Short-circuit-proof output Status display of the switching status with LED Product description The connector switching amplifier type VT-SSBA1 is directly mounted at the K4 connector of the valve. It is supplied with 24 V direct voltage. If at wire 2 (enable "IN"), a high-signal is applied, the voltage profile is applied at the valve according to the functional diagram. If the enable input is switched, the status display LED is flashing yellow. Fast switching ("V001") As fast switching amplifier, the connector switching amplifier type VT-SSBA1 considerably reduces the switching time of standard directional valves in connection with 12 V solenoids. On switching on, the solenoid is overexcited with 24 V by 100%. Afterwards, the voltage is reduced and the required holding current is set via pulse width modulation. Energy savings ("V002") If 24 V standard directional valves are used, the connector switching amplifier considerably reduces the continuous current to save energy. After a defined power supply time and the connected hydraulic switching of the valve, the system switches to pulse width modulation and the power is considerably reduced. This leads to a holding power under the power of a 24 V valve at 24 V supply voltage. Assignment of valves with their voltage version to versions "V001" and "V002", see "Technical data".
