Choosing a 48V DC Battery Voltage Monitoring Relay

Hi everyone,
Our company is developing a new product and needs to source a large quantity of 48VDC battery-voltage monitoring relays. Our application requires:
1. Monitoring a 48V DC bus
2. When the voltage drops below a set threshold (around 42V), a no-volt contact should energize to start our charging system
3. When the voltage returns to normal (around 51V), the contact should release
Can the DVRD-48 perform this function?
Thanks for any guidance!

Thanks for any guidance!Hi Michael,
1. The DVRD-48 can monitor a 48V DC bus, but its over-voltage setting range is 52–68V DC. If you need the recovery/over-voltage point at 51V, it doesn'tot meet your requirement.
2. If you need the over-voltage/recovery point adjustable between 51–80V, we recommend the SVR1000/AD48, which supports 20–80VDC adjustment.
