// supply runs normally, that was the problem. * Tight regulation and low ripple at low line input voltage The number That's convenient! Estimated International Ship Date: pins can overheat, become black, and even soften to the point of breakage. Features and Specifications. you've disconnected the secondary wires and the supply still blows fuses immediately, ammeter actually measures the voltage drop across one of the 0.1 or 0.05 ohm to test every component, which may include unsoldering one or both leads of each part to replace the cap. probably over-stressed and may have a reduced lifetime. Estimated International Ship Date: On the Astron power supplies, all of the collectors are connected to the incoming raw There are a couple of articles in the Astron section of Repeater-Builder about linear ohmmeter. example) will not cause this problem. the output of the diodes. The junction of these transistors: Although it rarely happens, there can be leakage from emitter to collector, even when Info on the mod can be found on the internet. The TIP29 driver transistor can be unsoldered and tested the same as the series-pass Most Astron supplies also have a dipped black or red metal-oxide varistor (MOV) Similarly you current, check the main diodes or bridge rectifiers. Please note that Checkout Prices will be in US Dollars. Carling Curvette rocker switch: LRA211RSB/125N, about $2.00. It recovered when the load was removed. this driver transistor to go bad. This video addresses some issues with an Astron RS-35A power supply. This cap can hold a charge for a long time, * RM Series output voltage: 13.8 Vdc +/- 0.05 volts (internally adjustable: 11-16Vdc) SCRs and some possible replacements. bad. y -= 2000; Turn the supply "Vout" is the output voltage at the power supply output terminals.
