Peak output DC current is the DC biased current flowing through the output. Maximum duration is 1 second. Metal case (pin 7) should either be tied to +INPUT (pin 4) or -INPUT (pin 3) directly or through a capacitor (>10nF). Remote pins are inputs of an opto-isolator, with an internal 330 1/4W resistor in series. SWG75-48S75C01/P has the same input and output specifications except the remote control logic is reversed. 0.890 (22.606) 1.280 (32.512) PIN DIA.
