| - | The Model 962 Power Supply is designed to power the TEN-TEC Models 560/561/563/564 and 585 transceivers. The supply delivers 20 amps at 13.5 Vdc from a 115/230 Vac 50/60 Hz source. Circuit features include an electronic over-current sensor which shuts off the output if the current demand exceeds 22 amps. The over-current shut down condition is reset by cycling the POWER switch from ON to OFF and back to ON. | + | The Model 962 Power Supply is designed to power the TEN-TEC Models [[560]]/[[561]]/[[563]]/[[564]] and [[585]] transceivers.

| + | The output voltage is available through a 4 x 14 guage 3 foot cable and connector. The cable carries +13.5 Vdc, ground and the "hot" side of the AC primary and mates directly to the POWER jack on the [[560]]/[[561]]/[[563]]/[[564]] and [[585]] transceivers with a [[80572|4 pin AMP MATE-N-LOC]] connector. Two RCA phono jacks on the back of the supply also provide +13.5 Vdc for low current (2 or 3 amps) auxiliary applications. | ||
