Kelly KHS High Voltage Sinusoidal Brushless Permanent Magnet Motor Controller User’s Manual V 1.25
2.4 Name Regulation
The name regulation of Kelly KHS motor controllers:
KHS-I/IPS
KHS: Kelly high voltage BLDC motor controller based on sine wave. KHS-N is supposed
to work with brushless motor with three hall sensors. KHS-NPS can work with Sin/Cosin
speed sensors. There are +5V, Sin,Cosin and GND I/O ports for brushless motor with
Sin/Cosin speed sensors.
I: It is designed by opto-isolated technology. We specify 9-32V for power supply which
must be isolated from main battery pack B+/B-.

Note: Continuous current was calculated based on controller with liquid cooling bottom plate.
Chapter 3 Wiring and Installation
3.1 Mounting the Controller
The KHS controller can be oriented in any position which should be as clean and dry as
possible, and if necessary, shielded with a cover to protect it from water and contaminants.
To ensure full rated output power, the controller should be fastened to a clean, flat metal
surface with four screws. Applying silicon grease or some other thermal conductive material to
contact surface will enhance thermal performance.
Proper heat sinking and airflow are vital to achieve the full power capability of the controller.
The case outline and mounting holes’ dimensions are shown in below Figure.
