Controller Manual — Curtis 1520

Built-in high-pedal-disable (HPD) and missing-potentiometer protection prevent runaway vehicles.

Matches the controller to the specific throttle mechanism (e.g., 0-5kΩ, 5k-0Ω, or 0-5V).

The Curtis 1520 is a high-frequency, programmable DC motor controller designed primarily for material handling equipment, light electric vehicles, and industrial automation systems. Known for its robust power management and smooth acceleration control, the 1520 series is compatible with separately excited (SEPEX) and permanent magnet (PM) motors, making it a versatile choice for OEMs and maintenance technicians.
