DG-Mini is an advanced all-inclusive variable speed door controller for motors up to 2 hp at input voltages or either 120 or 230 v single-phase.

DG-Mini is an advanced all-inclusive variable speed door controller for motors up to 2 hp at input voltages or either 120 or 230 v single-phase.  Both provide a 230-v 3-phase output for the motor.  Unique to the overall design is a single processor handling both logic and power for immediate response to any situation.  Additionally, the logic and power boards are both physically and electronically separated for maximum isolation.
When coupled with the proprietary BTR encoder, the system becomes a closed vector loop offering energy savings with real time torque control of the motor.  Doors will run smoother and last longer.
Included as standard is the BTR SeyWave® wireless system for door sensor and remote pushbutton operators.  It is an FCC and IC licensed product operating in the 2.4-GHz band for global acceptance.  The door sensor uses full two-way communications and dual verification of safety device operation thus complying with the UL325 Entrapment Standard.
An optional plug-in Wi-Fi module becomes a pipeline for wireless servicing and monitoring of all connected doors.  Through a proprietary cloud based subscription system and our Smart Device App, keeping track of door operation and condition is at your fingertips.
