The operation manual for the Drake SCHEMATICS PS-3 power supply covers the setup, operation, and troubleshooting of the unit, including details on voltage regulation, internal fuse specifications, and overload protection mechanisms. It also provides instructions for adjusting input voltages, resetting the power supply after an overload, and obtaining factory service for repairs.
Manual Overview
The Drake SCHEMATICS operation manual for the PS-3 power supply provides detailed instructions for troubleshooting, diagnostics, and maintenance. The PS-3 is a 13.8 Volt DC regulated power supply with a maximum current output of 8 amperes, protected by an internal 1 ampere MDL fuse. In the event of an overload or short circuit, the regulator circuit will shut down, indicated by the extinguishing of the “OUTPUT” (RED) panel lamp, while the “LINE” (AMBER) lamp remains lit. To reset, switch the power off and then on again. For calibration and adjustments, internal controls are factory set to maintain 13.8 volts, with short circuit protection set to shut down at less than 10 amperes. The power supply can accommodate primary voltages of 100, 120, 200, and 240 VAC with appropriate jumper wiring adjustments. For board-level guidance, the schematic diagram provides detailed configurations for components like transistors and fuses. Factory service is available for repairs, with prior authorization required.
Quick Issues Covered
- Diagnose power-up failures with PS-3's overload protection indicators.
- Identify error codes via panel lamp status for quick troubleshooting.
- Adjust output voltage/current using internal controls for calibration.
Overview
The PS-3 is a 13.8 Volt DC regulated power supply capable of supplying up to 8 amperes of current. It features excellent voltage regulation provided by a silicon monolithic integrated circuit, with output voltage and current adjustable via internal controls. The power supply includes short circuit protection, automatically shutting down when output current exceeds a preset value. It can operate with primary voltages of 100, 120, 200, and 240 VAC, 50-60 Hz, with proper wiring adjustments. The unit is fused internally and has an auxiliary DC output. Factory service is available for repairs, with prior authorization required.
