 ====== Power Supply Model 251 ======
 {{251.jpg?150|}}
 ===== Description =====
-  *Delivers up to 100 watts DC power from either 115 or 230 VAC, 50-60 Hz.
+The Model 251 Power Supply will deliver up to 9 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 10 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 gype 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.
-  *Output voltage regulated at 12.5 volts, nominal.
-  *Overload protection circuit.
