Continental Hydraulics are at the forefront of engineering hydraulic solutions for over 50 years-a testament to a long-standing reputation built upon your challenges and opportunities. A worldwide leader- a one-stop-shop for valves, pumps, power units and proportional products-all assembled in the USA.
The Continental Hydraulics CEM-AA power amplifier drives either single or dual solenoid proportional valve coils up to 2.6A. It is suitable to control current to proportional directional, flow or pressure valve coils. A wide range of analog signals are accepted. User may select either voltage or current input mode.These inputs are easily scaled to match system requirements. Four ramps are available for independently setting acceleration and deceleration in each direction. Min and Max output current are adjustable.
Output characteristics can be independently customized. The module is disabled if the coil outputs are shorted or open. If command current signal is outside of the proper range, the module is disabled. PWM and Dither are user adjustable. This module is easily adapted to a variety of system requirements. All variables are user adjusted with easy to use software on your Microsoft Windows® laptop. Control variables are stored in non-volatile memory internal to the module. All variables can be read by the laptop, and reproduced exactly on other modules
