Pacesetter Plus 24VDC PWM DC Drive 70A

Item # 910-3522-008

The IPC Automation Pacesetter Plus variable speed DC drive provides definitive control of permanent magnet motors and gearmotors used in battery powered vehicles and devices. Incorporating traditional IPC quality in a cost-effective small footprint package, the PLUS offers a host of standard features as well as extensive adjustment options available either factory pre-set or via on-board adjustment potentiometers. Designed for the realities of demanding vehicle usage, the Pacesetter's four-quadrant power stage incorporates rugged, high-speed FET's mounted on an efficient heatsink. Regenerative braking, on-demand high-current boost and anti-rollback circuitry all combine to provide powerful, smooth and silent drive performance, whether traveling uphill, downhill or over obstacles.

Simplified hook-up uses common "fast-on" connectors. In addition, standard protection circuitry prevents operation due to faults such as potentiometer/signal-input loss, reversed battery polarity, under-voltage and "throttle-not-at-neutral during startup" conditions. The Pacesetter Plus is a low cost no-compromise drive that provides you with the performance and features you need, the quality you demand, all at a surprisingly affordable price. Also available in 100 Amp output versions and programmable versions.

Features

24 Volt Four-Quadrant Operation - Provides true regenerative operation for excellent braking and speed control
Separate Accel/Decel Adjustments - Provisions for factory set resistors or on-board optional potentiometers
Anti-Rollback Circuitry - Minimizes roll back on hills by autosetting the brake delay function
Current Limit Protection with Peak-Boost Feature - Rated up to 70 amps peak 25 amps continuous. short-term boost feature for extra power in negotiating obstacles
Reverse Speed Max adjustment - Full Range Adjustment - factory set resistor or optional potentiometer
Input Pot Range Adjustment - Adjusts input gain to compensate for variations in pot Styles and Rotation - Factory set resistor or optional potentiometer
Input Pot Center Adjustment - Allows for easy adjustment of throttle neutral - Standard supplied potentiometer
Reverse Polarity Protection (Battery Input) - Prevents closure of the on-board "power" contactor - eliminates voltage blocking devices
Control Inhibit Input - (Logic High) use this input to disable the drive when charging the battery
High Throttle Monitor - Prevents operation on start-up until throttle has been returned to a neutral position
Brake Output - Provides separate output to a prake (2 amps)
Pot Loss Protection - Prevents operation when voltage is less than 16.5-17 vdc. protects motor, controller, and batteries
Anti-Plug Circuitry - Prevents instantaneous voltage reversal causing damage to the motor or controller
Neutral Throttle - Applies brakes when throttle is released or power is interrupted
Quick Connect Terminals - All connections to the controller are made through standard 0.250 "fast-on" connectors
