BD25A-AC Series BD25A-AC SERIES BRUSHLESS SERVO AMPLIFIERS Model: BD25A20AC 120 VAC, 50-60 Hz, Single Supply Operation FEATURES: • • • • • • • Surface-mount technology Small size, low cost, ease of use Input signal isolation Hall sensor input isolation Four quadrant regenerative operation Hall sensor commutation Agency Approvals: BLOCK DIAGRAM: ADVANCED MOTION CONTROLS 3805 Calle Tecate, Camarillo, CA 93012 Tel: (805) 389-1935, Fax: (805) 389-1165 B-25 BDC30A Series DESCRIPTION: The BD25A20AC Series PWM servo amplifiers are designed to drive brushless DC motors at a high switching frequency. They are fully protected against over-voltage, over-current, over-heating and short-circuits. All models interface with digital controllers that have a digital PWM output. PWM IN determines the output duty cycle. DIR IN determines the direction of rotation. They require a single AC power supply. A single red/green LED indicates operating status. The current limit can be set by DIP switches. SPECIFICATIONS: All BD25A20AC specifications are identical to the BD25A20 specifications (see BD30A Series) except for: MODEL POWER STAGE SPECIFICATIONS AC SUPPLY VOLTAGE SHUNT RESISTOR SHUNT SWITCH ON VOLTAGE BUS CAPACITANCE SHUNT FUSE (d = .25 inches, L = 1.25 inches) BUS FUSE (5x20 mm) BD25A20AC 30 - 125 VAC, 50 – 60 Hz 10 Ω @ 50 W 185 VDC 3600 µF 3 A Motor Delay rated @ 250 VAC 16 A slow-blow rated @ 250 VAC MECHANICAL SPECIFICATIONS POWER CONNECTOR SIGNAL CONNECTOR SIZE Screw terminals Molex connector 7.35 x 4.23 x 2.45 inches 186.7 x 107.4 x 62.2 mm WEIGHT 2.5 lb. 1.14 kg These amplifiers contain a rectifier bridge and filter capacitors to generate the DC bus internally from the AC input power. The DC bus voltage is 1.4 times AC voltage (RMS), e.g. 170 VDC from 120 VAC. During braking much of the stored mechanical energy is fed back into the power supply and charges the output capacitor to a higher voltage. If the charge reaches the amplifier's over-voltage shutdown point, output current and braking will cease. To ensure smooth braking of large inertial loads, a built-in "shunt regulator" is provided in the BD25A20AC. The shunt regulator will switch-on the internal power resistor when the bus voltage reaches 185 VDC. This resistor then dissipates the extra energy of the DC bus. APPLICATION NOTE: Contact factory for information regarding the use of the current monitor pin (P1-15). OPTICAL INPUT SIGNAL ISOLATION: PWM, DIR, INH, FAULT inputs are always isolated from the power section. On the BD25A20AC series the Hall sensor inputs (P1-10 through 14) are also isolated.

CURRENT LIMIT ADJUSTMENTS: These amplifiers feature peak and continuous current limit adjustments. DIP switches reduce both peak and continuous current limit. The ratio of peak/continuous current limit is fixed (50%). The switches also adjust the scaling of CURRMONITOR output.

OPTICAL INPUT SIGNAL ISOLATION: PWM, DIR, INH, FAULT inputs are always isolated from the power section. If the isolation option is selected the Hall sensor inputs (P1-10 through 14) are also isolated. If the isolated version is not ordered, an isolated power supply should be used with this series of amplifiers.
