FEATURES & BENEFITS
Typical Applications
n Reversing: Simple switch wired to terminal block allows you to quickly change directions.
n Speed range and regulation: .1% speed regulation over 80:1 speed range.
n User adjustable calibration pots: IR compensation, max speed, min speed, current limit, acceleration and deceleration.
n Diagnostic LEDs: LEDs for power, fault, torque limit and bus limit.
n Stopping modes: The user can brake (N.C.), decelerate (N.O.), or coast the motor to a stop (N.C.).
n Quick connect terminal block: Quick and easy wire terminations.
n On board power supply: 5VDC, 20mA supply for Hall sensors.
n 22kHz switching frequency: A high switching frequency means a quiet motor!
n Accepts AC or DC voltage: Accepts an AC or DC input voltage.
n Options and accessories: BOSSDB-115 for dynamic braking.
BOSS 1Q Series
Minarik’s BOSS Series of brushless drives provides an
exciting alternative to both AC and DC drives for
motor velocity control in applications 1/2 to 2 Hp.
BOSS drives incorporate the desirable attributes of
AC and DC systems: Little or no maintenance (no
brushes); compact, cool running, and quiet motor
operation; excellent speed range (80:1); .1% speed
regulation; quick response; high speeds; superb low-
end torque; and no audible switching noise.
Electrically commutated motors are driven from a
three phase “DC” output (trapezoidal waveform).
Standard drives output 4, 8, or 15 amps continuous
with peak currents reaching 200% of continuous rat-
ing for one second. BOSS drives use hall-effect feed-
back, 60° or 120° spacing, for accurate system oper-
ation.
A removable daughter card (personality module) lets
users add additional features to the BOSS drives and
creates a highly versatile product. Diagnostics
include a green power LED; a red current limit LED to
indicate continuous current limit; a red fault LED to
indicate open or mis-wired hall effect sensors, phase-
to-phase short-circuit, and peak current limit.
