Power Supply / Speaker Model 960



The Model 960 Power Supply is designed to power the Ten-Tec models 560/561 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. Output over-voltage protection is also included to prevent the output voltage from exceeding 16.0 Vdc.

The output voltage is available through a heavy duty 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 and 585 transceivers. Two RCA phono jacks on the back of the supply also provide +13.5 Vdc for low current (2 or 3 amps) auxiliary applications.
