Middex-Electronic K480216A-24 Two-Phase Stepper Motor Drive — Lot of 13
DIN rail mounted stepper motor driver, 20-48VDC, distributed via Phoenix Contact
Overview
This lot is 13 units of the Middex-Electronic K480216A-24, a two-phase stepper motor driver housed in a compact, DIN rail mounted plastic enclosure. It accepts a wide 20-48VDC supply (momentary up to 52VDC) and drives 2-phase step motors with selectable phase current settings, opto-decoupled pulse/direction signal triggering, and a "Ready" output signal via opto-coupler. Its design generates low heat without requiring forced cooling, making it well suited to compact panel installations.
Key Features
- Selectable phase current: Configurable at 1.0/1.5/2.0/2.5 Aeff per phase (1.4/2.1/2.8/3.5 A peak).
- Automatic current reduction: Reduces output current by 50% during idle/standstill periods, minimizing motor and driver heating.
- Selectable step resolution: 200, 400, 800, or 1600 steps/revolution.
- Flexible signal voltage input: Opto-decoupled pulse/direction triggering compatible with 5V (low -8, rated 5, max. 8V) or 24V (low -30, rated 24, max. 30V) logic levels.
- Opto-coupled Ready output: Provides isolated status feedback for integration into higher-level control systems.
- Compact, low-heat design: Approx. 79 x 25 x 86 mm (H x W x D), 80g, requiring no forced cooling under normal operation.
