... With Active-High, if the ENABLE pin is left floating, the supply will be enabled. Active-Low means that a logic low at the ENABLE pin will turn ON the supply. With Active-Low, if the ENABLE pin is left floating, the supply will be disabled. If remote On/Off is not used on an Active-Low supply, short the Enable pin to –Vin.

... WALL INDUSTRIES, INC. TEST SETUP: The SPW48S24-100 specifications are tested with the following configurations: Regulation and Efficiency Setup To ensure that accurate measurement are taken, the voltage measurements are taken directly at the terminals of the module. This minimizes errors due to contact and trace lengths between the load and the output of the supply. The following diagram is of the test setup ...
