All New OEM Capacitor Charging Power Supply Design Kickoff

Coming October 2020

New Models 5727A and 5728A OEM Capacitor Charging Power Supplies

AMI is excited to announce the kickoff of a new program to design a state-of-the-art new OEM Capacitor Charging Power Supply!  The new supply will feature active power factor correction, universal input and full compliance with medical safety standards.  Modern components and manufacturing techniques will be used to provide the reliability and unmatched quality our customers have come to demand at a price point that is competitive in the market.

Capacitor Charging Power SupplyThe Models 5703A & 5704A have been the industry standards for power density, best voltage vs. power curve and rock solid reliability. Manufacture’s of flashlamp pumped solid-state lasers for medical, industrial, military and research applications have come to depend on AMI’s cap chargers.

The Models 5703A and 5704A have been in production for over 20 years with thousands of units running in systems across the world.  However, with the constant battle to find replacements for obsolete parts the time has come to create a new power supply that takes advantage of the latest components and modern manufacturing techniques.

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.
