Overview:

The 1228-2901 offers smooth, silent, cost effective control of motor speed and torque. A four quadrant, full bridge power output stage provides for solid state motor reversing and full braking power without additional relays or contactors.

Specifications:
* PWM operating frequency: 15 kHz
* Electrical isolation to heatsink (min.): 500 VAC
* Dielectric resistance: >1 MΩ (DC test)
* Heatsink overtemperature: linear cutback starts at 92°C; complete cutoff at 134°C
* Heatsink undertemperature: 50% armature current at -25°
* Undervoltage cutoff: 14 V
* Overvoltage cutoff: 34 V
* With kit of connectors & terminals

The CURTIS 1228 MultiMode™ controller is a permanent magnet motor speed controller designed for use in mobility aid scooters and other small electric vehicles, such as sweeper/scrubbers.
The 1228-2901 controller is fully programmable, via the CURTIS Model 1313-4331 Handheld Programmer or 1314 PC Programming Station.
This means the controllers can be tailored to the needs of specific applications. In addition to configuration flexibility, use of the programmer offers diagnostic and test capability.

inverted wigwag pot or voltage throttle
* 2 =
single-ended pot; maximum speed = 5kΩ
* 3 =
inverted single-ended pot; maximum speed = 0
* 4 =
single-ended voltage throttle; maximum speed = 5V
* 5 =
inverted single-ended voltage throttle; maximum speed = 0
