Acro Associates' new 900R solenoid control module is claimed to make solenoids three to 10 times more power efficient than with other control techniques, a critical factor in battery-powered applications.

The 900R contains a low-side FET power switch employing a pulse width modulated (PWM) output, which conserves energy and reduces waste-heat production. The unit also features Acro's 'adaptive' pulse and hold technology, which facilitates higher forces, longer strokes, and extended duty cycles by optimising power consumption. Integrated microprocessors analyse load current for additional power savings and short-circuit protection. The 900R provides up to 5A of drive current, and the user interface consists of an opto-isolated differential input port that can be directly wired to relays, transistor logic, digital I/O boards and PLCs.
