Station Powering Data
Data is based on stations configured for 2-way operation. AC currents specified are based on measurements
made with typical CATV type ferroresonant AC power supply (quasi-square wave), and GainMaker High Output
System Amplifier 24 V power supply, part number 4022846.
DC supply has a user configurable 30 V, 40 V, or 50 VAC under voltage lockout circuit. Default setting is 30 V.
40 V or 50 V AC under voltage lockout may be selected by changing the position of the lockout jumper.
