Common Specifications: Efficiency rating of 85%-90%; Power factor 0.92 (typical), regulation 0.1% (typical). All AC input power supplies can be factory configured for a negative output voltage. All 57xx capacitor charging power supplies are CE marked and certified to UL60601-1.
Specifications are subject to change without notice.


Like all power supplies, AMI’s supplies must be derated when operating at less than maximum output voltage. For most supplies, this rating is linear. For capacitor charging applications below 1500V, however, the 57X3 series of supplies can deliver up to 80% of rated power even when operating at 50% of the maximum output voltage.
DC input capacitor charging power supplies
Rugged and Reliable. AMI offers a broad line of compact, high voltage capacitor charging power supplies designed for use from a DC source. Available with a variety of output power levels, these modules are ideal for OEM applications. Based on a proven design topology, these modules have been successfully employed in both commercial and military systems since 1980.
