1520-5501 Curtis DC Motor 48V universal Speed Controller For Electric Vehicle

Specification:

• PWM operating frequency: 16 kHz
• Electrical isolation to heatsink (min.): 500 VAC
• KSI input voltage (minimum): 16.8 V

Overview:

CURTIS 1520 controllers are separately excited motor speed controllers designed for use in a variety of transport vehicles. These programmable controllers are simple to install, efficient, and cost effective. Typical applications include golf carts and small utility vehicles.

The 1520 controller offers smooth, silent, cost effective control of motor speed and torque. The speed sensor input allows superior closed-loop control for regulating vehicle speed. Unique braking parameters allow simple, intuitive deceleration tuning. A full-bridge field winding control stage is combined with a half-bridge armature power stage to provide solid state motor reversing and regenerative braking power without additional relays or contactors.
