What is the overvoltage regulation range of the voltage monitoring relay?

The overvoltage regulation range of the voltage monitoring relay is 13-17v.

What are the typical applications of the voltage monitoring relay?

The voltage monitoring relay is typically applied in dc motor, battery,UPS power supply, dc switchgear, dc panel, industrial control system.

What is the installation method of the voltage monitoring relay?

The voltage monitoring relay comes with a 35mm guide rail and standard modular structure, making it easy to install and operate.

Low voltage cut off at 42 and high at 52. Why do both relays trip?

It may be the relay is defective. But try increasing the gap between low and high settings and decreasing the time delay setting by around 1 second.

Is there a way to turn off the low voltage setting?

Yes, just don't use the undervoltage relay contacts and only use the overvoltage relay contacts.

How much current does the device draw at 12vdc?

The operating current is insignificant, enough to run a small LED or two.

Can I wire before the fuse panel in RV to cut off DC if it goes above 13 volts?

Yes, you can use the output signal to drive a relay in line with the supply to the fuse panel.

What do the dials on the unit control?

The top dial sets the high voltage limit, the middle dial sets the low voltage limit, and the lower dial sets the time delay.

At what voltage does the relay reset for a 48v unit set for 43v under voltage?

The relay will reset as soon as the voltage goes back above 44.0 to 44.5 V.

Do you have a similar concept for DC voltage up to 150v?

No, a DC-rated contactor would need to be used for that.

Why do both relay NC contacts move simultaneously to NO terminal when the input is within the range?

The relays are independent and will trip/reset simultaneously within a 1-1.5V hysteresis.

Is it a DPDT relay or independent ones for high and low voltage disconnect?

There is one SPDT relay for overvoltage threshold and one SPDT relay for undervoltage threshold. They operate independently.

What do the labeled connections 28(24), 25(21), 26(22), 18(14), 15(11), 16(12) mean?

It refers to the internally used contacts for operating relay coils. The available contacts at those connections are isolated from the input and support 250VAC and up to 6 Amps.
