Ordering information of latching relay

On the face of relay products with various specifications, how to choose the right use of reasonable, will directly affect the performance and reliability of the whole product.Then what are the problems that should be paid attention to when buying relays? Let's look at them from the following points.

1.Make a choice between magnetic immune latching relay and magnetic latching relay: before make such choice, you must clearly know that the difference between such two kinds of latching relay~ 1)Different Driving Mode, the magnetic immune latching relay is driven by motor, magnetic immune latching relay is driven by coil, 2)Whether or not need the function of resist magnetic influence up to 500mT, the magnetic immune latching relay has the function, magnetic latching relay can only realize it by metal case. This is point is the first step when you want to purchase a latching relay.

2.Rated Load: It includes Max. Switching Voltage and Max Switching Current, compact switching voltage commonly is around 250VAC, maximum switching current commonly is around 100A. When talked about this, we have to mention IVY Metering CO., LTD, which can provide 32~200A latching relay. It can meet every people demand,  Specially, they recently developed IM801D, a mini two phases 80A latching relay.this company website is https://www.ivy-metering.com

3.Contact Form: it includes Single/Two/Three Phases,the most common still are single and three phase.

4.Coil Voltage: 6~48VDC

The common coil voltage range of magnetic latching relay is 5-48VD, 6-48VDC and 9-48VDC, while the coil voltage range of magnetic Immune latching relay is 9-36VDC, among which the driving voltage is the most common 9/12/16/24/48VDC

5.Single/Two Coil Voltage: For single coil, the fault state cannot be maintained, Double coil relays are often used for anti - trip and signal relays.

6.Coil polarity: Coil polarity can be divided into the following two categories :for single coil +-, -+, for dual coils +-+ and -+-. It is necessary for customers to choose one that suits them.

7.Fully customized output termination, primary current and ratio for easily  integrate into your meter.It able to Integrate shunt ,copper braided cable, copper blade or terminal block available.

In addition to the above essential ordering elements, you may have certain requirements on pickup & release time according to the different needs of the power company. At this time, you need to make specific analysis on specific circumstances.
