Kevin, I don't believe the RLC-3 manual had specs, but surely it's under 1 amp. If the power supply feeding the controller is at least 13.2 volts, you can put a 1-ohm resistor rated for at least 2 watts dissipation in series with the [+] power lead feeding the controller, use a digital voltmeter to read the voltage across the resistor, and it will directly read current in amps.
(For example, ".200" is 200 milliamps, etc.) The controller will actually draw a few milliamps less running through the resistor, as its linear regulators will dump less waste heat, but you can at least get it ballparked. 73, Paul, AE4KR ----- Original Message ----- From: Gmail - Kevin, Natalia, Stacey & Rochelle To: [email protected] Sent: Wednesday, April 01, 2009 8:54 PM Subject: [Repeater-Builder] Anyone got a Amp-meter Circuit to Repeater Controller for Telementry Readback? Hi All, I am in need of a circuit to read amps to my controller. Want to be able to read the current being used at the repeater site as well as the charging current to the batteries. I am using a RLC-3 controller. I have a current meter in-line at the site, but a reference from the repeater would be a great help. Thanks Kevin, ZL1KFM.
