Alternating Relays can be used in various ways in applications that need to control and balance the wear between pumps, compressors and other rotating machines. The most basic of the relay family is the variant that simply requires one input to control the outputs which are connected to two loads. <...

Fundamentally, both timers are similar in that they provide a delay period that the relay remains energised for from an initial trigger. However, the trigger method for both is different. True Delay Off - This timer utilises storage capacitors internally which retain their charge when the power is ...

A phase loss fault is the condition caused by blown fuses, tripped circuit breakers, cable damage, open circuits, poor/loose connections and worn contacts. Allowing this fault to persist can lead to equipment failures and machine downtime. Read more

A phase reversal fault is a situation where two phases in a three phase system have been swapped. This typically occurs during equipment installation, upgrades or general maintenance. 3-phase motors and other rotating equipment rely on the order of the phases to be correct. That is, L1, L2 and L3 ...

Undervoltage is defined as a condition where the applied voltage drops to 90% of rated voltage, or less, for at least 1 minute. This condition if allowed to persist, can expose electrical devices to problems such as overheating, malfunction, premature failure and shut down, especially for motors (i.e. refrigerators, dryers and ...
