However, an AC stabilized (50Hz) power supply should be used to minimize the influence of AC primary side flicker noise on the reading. *4: Use the transformer power supply circuit shown in the figure below for allowable load shorted time measurement. *5: Please connect –Pre VCC pin (#1 pin) with the stable minimum voltage and connect so that current does not flow in by reverse bias. * Thermal design must be implemented based on the conditions under which the customer’s end products are expected to operate on the market. * A thermoplastic adhesive is used to adhere the case. 10000 μF 10000 μF DBA40C 500 Ω 500 Ω +VCC -VCC + + Designated transformer power supply (MG-200 equivalent) |
