Continental Hydraulics CEM-AC – Single Channel Power Amplifier

~ scroll down to find the part you need ~
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 Hydraulic CEM-AC power amplifier mounts directly to a single solenoid proportional valve coil with a DIN style connector,
and will drive up to 2.5A. It is suitable to control current to either a proportional flow or pressure valve coil.

A wide range of analog signals are accepted. There are two product choices for input; one accepts voltage commands,
the other accepts current commands. These inputs are easily scaled to match system requirements. Two independent ramps are available for acceleration and deceleration control.

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 is outside of the proper range, the module is also 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
