Multi-Unit Rectifier Controller

Dynapower’s new Multi-Unit Rectifier Controller can control between one and ten rectifiers from a single user-friendly touchscreen that can be centrally located in any facility.

The Multi-Unit Rectifier Controller works with both silicon controlled rectifiers and switchmode power supplies or a combination of up to ten Dynapower power supplies of varying sizes.

Dynapower’s Multi-Unit Rectifier Controller allows users to save time with the automation of recipes, fault diagnostics, and data logging of multiple rectifiers from a single touchscreen.

The Multi-Unit Rectifier Controller can be easily retrofitted to existing Dynapower rectifiers to modernize the control of your power supplies.

Program Mode: Up to 12 programs (8-steps) can be stored, copied and deleted. Steps include voltage/current ramping, constant and pulsing with voltage, time, and AH step limits. Steps can be jumped to and repeated to create complex waveforms. Program review shows all program parameters for each step on one screen for better overview of program.

To ensure all audit requirements are satisfied, the Multi-Unit Rectifier Controller features data logging for objective evidence. The data logging feature saves detailed DC voltage and current feedback & setpoint data and reports upon the completion of every successful finishing cycle. All history is easily accessible for download and review for record keeping.
