7CH100 ONE QUADRANT CONTROLLER FOR PM AND 3 CLAMPS DC MOTORS

Product catalog summary

Introduction
The 7CH100 is a one-quadrant chopper controller designed for PM and 3 clamps DC motors, powered by 12V, 24V, or 36V batteries. It operates with a PWM frequency of 300 Hz and is suitable for applications such as electric vehicles and scooters. The design complies with key EC standards.

Features

Power Supply: 12V, 24V, 36V
Rated Current: 50 A (dependent on dissipation)
Max Current: 120 A at 25°C
Frequency: 300 Hz
Operating Temperature: -10°C to 40°C
Speed Reference Potentiometer: 1-5K
Size: 130x100x65 mm (51.18x39.37x25.59 inches)

Safety Features

Breaking Potentiometer
Enable Input
Thermal Protection at 90°C

Calibration

Acceleration Ramp (ACC): 0.5 – 3 s
Minimum Speed (Vmin): 0-30% V Battery
Maximum Speed (ESC): Potentiometer Angle
Maximum Current (Imax): 50 – 120 A

Installation
The chopper should be installed in a location protected from mechanical damage, water, and dirt. It should be mounted on a metal surface, preferably aluminum, to enhance heat dissipation. If thermal protection frequently activates, additional cooling measures like a heat sink or fan are recommended. Note that the controller is not protected against reversed battery connections. The speed controller can be made bi-directional with an appropriate mechanical contactor.

I/O Connector

Pin 1: Key switch input (+V battery)
Pin 2: Enable contact (enabled when closed to -Vbatt)
Pin 3: Positive Potentiometer Supply
Pin 4: Central Potentiometer
Pin 5: Negative Potentiometer Supply
