    MX4660 shunt regulator option

    I have an email in to Leadshine, but have not heard back yet.
    For those of you who might be familiar with this driver and the use of shunt regulators, I was hoping to get feedback on whether the model I am considering is appropriate.
    The driver runs 4 NEMA 23 3.5V 4.2A steppers which are powered by a 48V 12.5A PSU.
    I have a quote for an Advanced Motion Controls SRST70, which I have seen recommended by Leadshine in one of their support documents, but it is much more expensive (at least from their distributor here in Canada). I also like the one I found as it allows a range of clamping voltages to be set.
    I appreciate any insights that can be offered.
