LORD USER INSTRUCTIONS LORD Wonder Box® Device Controller Kit LORD Wonder Box® device controller kit is a companion product for the magneto-rheological (MR) fluid devices. The kit includes the device controller, 12 Volt DC power supply and two banana plugs. The output current is linearly proportional to the input voltage. The output current will be 0.0 Amps when the control input is approximately 0.4-0.6 Volts at the BNC terminal (refer to Typical Performance graph). The Wonder Box device controller kit provides closed loop current control to compensate for changing electrical loads up to the limits of the power supply. The Wonder Box controller may be operated as an interface device for PLC or computer control of MR fluid devices. The Wonder Box device controller kit is for indoor use only. Pulse Control If manual operation is desired, a potentiometer is provided to control the current supplied to an attached device. In Manual or External Voltage Control, current to the device may be switched on and off by depressing the switch on the side of the controller (E). Technical Data Overall Dimensions (LxWxH), mm (in) 63.5 x 27.9 x 88.9 (2.5 x 1.1 x 3.5) Input Receptacle 2.1 mm Female Pulse Width Modulation (PWM) Frequency, kHz 30 Output Current, Amp 2 max Operating Instructions Connect the banana plugs to each wire of the MR fluid device. Insert the banana plugs into the Wonder Box controller output (B). Polarity is not important. Connect the power supply to the input connector (A). The red LED should light indicating proper operation of the unit. Wonder Box Device Controller Manual Control B Current to the device is adjusted by rotating the potentiometer (C) in the clockwise direction. An external voltage control input should not be connected to the BNC terminal (D). E External Voltage Control With the potentiometer control set to zero (rotate fully counter clockwise), connect a 0-5 Volt DC control signal to the BNC terminal on the side of the Wonder Box controller (D). Output current to a device can now be controlled with this input signal. The input control signal can be switched up to 1 kHz.
