Power Supply Model 252G


The Model 252G Power Supply will deliver up to 18 amperes at approximately 13 VDC, regulated, from a 117 VAC 50-60 Hz source. An electronic latching circuit breaker shuts down the output voltage when a current in excess of 20 amperes is drawn from the supply. Reset is accomplished by cycling the POWER switch. Two indicator lamps monitor the LINE and OUTPUT voltages. The primary circuit is fused with a slo-blo fuse. The output voltage is available through a six pin Jones connector and a phono type jack for low current applications. Two of the six Jones pins are used for remote power on-off switching, if desired. Will accept the Model 207 ammeter.
