Smart Power Dump
PRESS release: April 2023
Birkerød, Denmark - JVL A/S, one of the world’s leading producers in the field of integrated servo and stepper motors, is announcing our own plug-n-play power supply optimizer – PDA072. This is an automatic power dump circuit and CVI control voltage power supply, that will protect both your motor and power supply.
Have you ever experienced that your power supply shuts down when your motor is slowing down?
This is because your motor will produce return energy when decelerating, also called back-emf. With the new power supply optimizer, this is no longer a problem! With the built-in power dump circuit, both your motor and power supply are much better protected.
How it works:
When the motor generates energy back to the supply line, the output voltage of PDA072 can exceed the input voltage. The PDA072 detects when the output voltage is 2-4 volts higher than the input voltage and activates the internal power dump resistor to bring the voltage back down. The "PD active red" LED remains lit while the resistor is active.
If the internal power dump resistor heats up to a critical temperature (approximately 80-90°C), the temperature sensor will deactivate the power dump resistor to prevent permanent damage. The "PD too hot" LED will remain lit as long as the temperature is too high. A notable feature of the PDS072 is its ability to operate at any voltage from 8-72V, including 12V, 24V, 36V, 48V, and 72V DC.

Easy plug-n-play installation
The power supply optimizer uses the same industrial grade M12 connectors as you find in our integrated motors.
It is easily inserted in-line with the power cable you use for your DC driven JVL motor.
It will automatically adjust to the voltage level you use, so you order the same part number for 12Vdc battery applications as you do for high-power 72Vdc applications.

Retrofitting without any further installation or settings needed
If you have already installed a motor in your machine, and experience over voltage errors, you can simply retrofit the PDA072 in-line with the standard JVL power cable – no further installation or settings are required!
