Open the catalog to page 2Note: 1. For further ripple & noise reduction, connect an additional capacitor each with a value between 1uF and 10uF in parallel with capacitors C2 and C3. 2. If the input impulse voltage is too high, the current-limiting resistance can be adjusted to meet the requirements of the input impulse current. A high-speed opto-coupler LED with a 200 a series resistance is connected in between the signal input terminals and the current-limiting resistance can be calculated according to the following formula: 3. For harsh applications in environments with long wires, we recommend adding an...

The built-in isolated DC-DC power supply is for internal driver use only and cannot be used for external connections. We recommend the output filter capacitor value not to exceed 220uF; 3. The driver must be wired as short as possible to the IGBT module's gate and emitter terminals (1 m max.); 4. Twisted pair is recommended for the connection of the driver to the gate and emitter of the IGBT; 5. In order to reduce the high peak voltage generated at...
