ALE Capacitor charging power supplies are specifically designed to efficiently charge capacitive loads to high voltages with excellent pulse to pulse repeatability at very high repetition rates. Capacitor charging supplies differ from conventional DC supplies in that the output current is fixed and not variable, allowing the load capacitor to be charged in the fastest possible time, with no requirement for series current limiting resistors. All of ALE's capacitor charging supplies have a fast inhibit input. This allows the user to start and stop load charging with a simple 0-10V input signal.

This feature is particularly useful in repetitive discharge circuits where inhibiting the supply output current after the load has been discharged aids in switch recovery. In addition to the fast inhibit control all of the standard power supplies feature a comprehensive control interface with programming and status signals.

The capacitor charging supply was originally designed to replace large command resonant charge supplies in high performance lasers. Even today the largest application for this type of supply is the laser industry. Although lasers are the largest users of capacitor charging power supplies, they also find applications in areas as diverse as medical sterilization and rock crushing.

Switchmode High Voltage DC
Although the ALE series of power supplies have been designed to operate as constant current capacitor charging supplies, they can be used in continuous DC applications with the addition of an external filter capacitor. When used in DC applications the ALE series can often deliver more average power, see the product details for the actual rating.
