4.3 POWER CONNECTION

The Model 2121/2135C offers either an AC or DC power sup-

ply.

The 2121/2135C provides a strap selectable power supply.

4.3.1 AC Power Supply (100-240VAC)

The Model 2121/2135C uses a 5VDC, 2A universal input 100- 240VAC, power supply (center pin is +5V). The universal input power supply is equipped with a male IEC-320 connector. This power supply connects to the Model 2121/2135C via a barrel jack on the rear panel. A variety of international power cords are avail- able for the universal power supply.

The Model 2121/2135C powers up as soon as it is plugged into an AC outlet. The unit does not have a power switch.

The 2121/2135C is factory set to be used with the AC power supply.

Note: Default setting has strap on position 7 and 8 on J3 for AC power supply. See figure 4 below.
