Notes

1

1 bell = 3k

Ω in series 1.2µF, 82 bells = 36Ω in series 98µF.

2

Peak output DC current is the DC biased current flowing through the

output. Maximum duration is 1 second.

3

Metal case (pin 7) should either be tied to +INPUT (pin 4) or -INPUT (pin 3)

directly or through a capacitor (>10nF).

4

Remote pins are inputs of an opto-isolator, with an internal 330

Ω 1/4W

resistor in series.

5

SWG75-48S75C01/P has the same input and output specifications except

the remote control logic is reversed.
