Mt switch has stored energy but the device cannot store energy

How do I use MT40 to monitor power consumption?

In order to monitor and control power for an electrical device, MT40 must be connected between upstream power and the device "in-line" with the device’s power supply. When using MT40 to monitor power consumption of a switch, the MT40 should be plugged into the power outlet, and then the switch should be plugged into the MT40.

What is a stored energy mechanism (SEM)?

A Stored Energy Mechanism (SEM) is a mechanism that opens and closes a device (Switch) by compressing and releasing spring energy. The operating handle compresses a set of closing springs and a separate set of opening springs. These springs store the mechanical energy of this movement and are held in the compressed state by close and open latches.

How can MT40 help reduce energy consumption?

Monitor, evaluate and optimize energy costs across devices: MT40 can provide benchmarking for how much energy is being consumed by different devices, and measure the effect of different initiatives to reduce energy consumption. MT40 can also be used to turn off devices when they are not needed to save on energy usage.

Where does energy come from when a switch is turned off?

For a hard switching circuit, during turn off, the energy that is dissipated in the FET during turn on originally came from Vin. This means that some energy is stored in Coss. (Idrain is divided among the channel and Coss).

Can a machine/equipment reaccumulate stored energy after shutdown?

The machine/equipment has no potential for stored energy or reaccumulation of stored energy after shutdown, which would endanger employees. The machine/equipment has a single energy source that can be readily identified and isolated. Isolation and locking out the energy source will completely deenergize the machine/equipment.

Can MT40 be connected to a power strip?

MT40 can be connected in-line with PDUs or power strips. Keep in mind that if a customer turns the power off on a power strip or PDU, it will override the power on/off state for MT40. Can MT40 be used with an uninterruptible power supply (UPS)?
