Capacitor Charging Power Supplies

Two Designs for Fixed and Variable Pulse Width Applications

Capacitor Charging Power Supply

AMI offers two capacitor charging power supply designs.  The Model 5703A is designed for charging deep cycling capacitors typical of fixed pulse width SCR switched systems.  The Model 5704A is designed to keep a bank of capacitors constantly charged to a programmed voltage typical for variable pulse width IGBT switched systems.

Model 758B.1

Based on the field proven performance of AMI’s 758 Series Laser Rangefinder Receivers, the Model 758B.1 extends the capabilities even further with outstanding double-pulse discrimination. This allows a weak target to be seen through a close, partly obscuring strong target. Multiple Target Resolution is 12 meters typical over 6 orders of magnitude with the second pulse 10dB down.
