BLM700 Brushless DC Drive /Tachometer
A compact, programmable brushless DC speed control with digital
closed loop feedback and LED display for BLDC motors rated to 400
Watts. Dart’s BLM700 Brushless Micro-Drive is the ultimate value in
ENERGY EFFICIENCY, accuracy and control.
The Brushless Micro-Drive is simple to operate: set the desired RPM,
rate, or time in the large 1/2″ LED display by depressing the “Up” and
“Down” pushbuttons on the front panel. Settings can be one digit at a
time or fast sweep. The settings are exact and repeatable. It will
precisely control speed to ±1/2 RPM of set speed, long term. No
calibrations of the control are necessary. Industry standard cutout
dimensions of 1/8 DIN provide easy panel installation. All wiring
connects directly to a rugged screw type terminal strip through the rear
panel. The flexibility of Dart’s BLM700 Brushless Micro-Drive design
makes it uniquely suited for many commercial and industrial
applications.
