7CH220T(110T) ONE QUADRANT CONTROLLER FOR PM 180 VDC MOTORS

Product catalog summary

Introduction
The 7CH220T(110T) is a one-quadrant chopper controller designed for PM DC motors operating at 180 VDC. It features voltage feedback and is powered by a 230 VAC (or 115 VAC) mains supply. The controller uses a MOSFET power stage with an 18 KHz PWM frequency, ensuring high efficiency due to low current ripple. It complies with key EC standards.

Features

Power Supply: 230 VAC – 50/60 Hz (115 VAC)
Rated Current: 2 A (dependent on dissipation)
Max Current: 6 A at 25°C
Frequency: 18 KHz
Operating Temperature: -10°C to 40°C
Speed Reference Potentiometer: 10 K
Voltage Feedback
Size: 115x100x35 mm / 45.27x39.37x13.77 inches
Safety: Thermal protection at 90°C

Calibration

ACC (Acceleration Ramp)
Vmin (Minimum Speed)
Vmax (Maximum Speed)
Potentiometer Angle

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 during normal operation, additional cooling measures such as a heat sink or fan may be necessary.
