If you switch the poweron and off at he secondary side (24 V DC), you can cause the fuses to blow.PowersupplyPrimarysideSecondaryside100 VAC–+24 V DCMicroImage-CheckerPrimary side Secondary side100 VAC +24 V DCMicroImage-CheckerIncorrect CorrectPowersupplyUse a power supply that has sufficient surplus capacity!− When you first switch the power on, the temporary in−rush current far exceeds therated current. Therefore, be certain to use a power supply that has sufficient surpluscapacity to handle this (i.e. rated at about three times the steady−state current), andtest it to ensure that it operates correctly.
