Santerno AMS90/1 AC/DC Drive

The AMS90/1 drive is engineered to provide efficient control for DC motors in various industrial applications. It operates with a single-phase 230/400V AC power supply, adjustable via a voltage change jumper, and supports both 50Hz and 60Hz frequencies, selectable through a dip-switch. The drive delivers an armature voltage ranging from 0 to 280V DC and includes a built-in single-phase rectifier bridge with suppression varistor for field excitation. Its design ensures galvanic isolation from the mains when using tacho generator feedback, enhancing operational safety.

Features:

• Power Supply: Single-phase 230/400V AC with ±15% tolerance; 50/60Hz selectable.
• Armature Voltage: 0 to 280V DC (with 400V AC input).
• Control: Analog circuit for speed or torque regulation.
• Feedback Options: Supports tacho generator feedback with automatic polarity correction and high-impedance armature feedback with R x I drop compensation.
• Inputs: Two speed inputs (direct and ramp) via 0 to +10V DC voltage reference; one direct input via 4-20mA current reference.
• Outputs: Analog voltage signals proportional to motor speed and armature current.
• Protection: Adjustable current limit via internal trimmer or external 0 to -10V DC signal.
• Mounting: DIN rail or panel mount.
• Dimensions: Compact design for easy integration.
• Operating Conditions: Ambient temperature 0 to 40°C; relative humidity 20-90% (non-condensing); altitude up to 1000m with derating above.
• Weight: Approximately 2.65 kg for AMS90/1.10 and 1.20 models; 3.3 kg for AMS90/1.30 model.
• Protection Rating: IP20.
