Single-direction PWM for low-voltage PLN series small DC motor control; there are two different types, as shown in the characteristics, catalogue and manual.
The main features of low voltage single direction PWM DC motors control PLN 19-8 are:
Line voltage at terminals FA1 and FA2: 12 – 24 Vac or 15 – 35 Vdc
The speed of the drive is to be controlled by potentiometer, 10-15 KΩ
Current Limit trimmer, in order to suit the board for small motors. In order to limit the current, turn clock wise the trimmer
Output voltage from terminals FA3 and FA4, from 0 up to Vdc MAX which is proportional to the input voltage. With 35 Vdc input voltage, the max output voltage is about 30 Vdc
Output current (*): Maximum output current allowed: 8 A in a ventilated environment, continuous duty.
Weight: 0.120 Kg
The main features of low voltage single direction PWM DC motors control PLN20 – PLN40 are:
Transistor bidirectional drive with regenerative current system.
Following settings can be adjusted (by built in trimmers): acceleration ramp: 0.5 - 10 sec, deceleration ramp: 0.5 - 10 sec, current limit 100% - about 30%
Room temperature: 0°C / +40°C (alarm below zero)
LED for system diagnosis
Switching frequency: 16kHz
Covered
5-10 kΩ Speed pot. or 0-10 Vdc external signal for speed regulation
