The 977HL Pulsed DC controller is used with the Meech model 976EX hazardous area ionising bars. In-built performance monitoring guarantees that the operator can keep the ionising system running effectively: ensuring correct static control in critical applications.

Additionally, closed-loop control can be achieved by the addition of a sensor bar to get the most accurate static control possible. Local displays and remote outputs provide clear information of system health.
