The Ametek/Elgar 4643V is a dual-range manual oscillator module that delivers stable, precise frequency output for integration with Elgar AC power sources. This Series 400 plug-in unit provides decade-dial and range-switch control over frequency selection, enabling low-distortion sine wave generation across 45 Hz to 5 kHz. Manual frequency adjustment combines with optional external programming via analog voltage (6-10 VDC) or external resistance to meet diverse test and calibration requirements. Calibration accuracy of ±0.001% of set value and a front-panel frequency-limit LED ensure reliable operation within specified bounds. The module accepts single, dual, or three-phase configurations and integrates directly into Elgar power sources via captive-screw front-panel mounting and terminal connector interface.
