Power duration measurements Power duration measurements record the elapsed time after the introduction of a power step until the output is attenuated to a safe power level by the onboard protection system (Please refer to page 12 for a full description). Measurements marked with * indicate loss of output power. • Stepping the power load on the ASP-module Module Input Frequency Preload power Stepped power 1000ASP 880 Hz 500 W @ 4 Ω 1000 W @ 4 Ω 500A 1 kHz 500 W @ 4 Ω 500 W @ 4 Ω Power duration [ms] (t 150 ) 1000ASP 500A 80 Volt bus without extra capacitor 33 40 80 Volt bus with extra capacitor 9400 uF 55 50 • Stepping the power load on the hanger module Module Input Frequency Preload power Stepped power 1000ASP 880 Hz 1000 W @ 4 Ω 1000 W @ 4 Ω 500A 1 kHz 0 W @ 4 Ω 500 W @ 4 Ω Power duration [ms] (t 150 ) 1000ASP 500A 80 Volt bus without extra capacitor 33 40 80 Volt bus with extra capacitor 9400 uF 55 70 Page 38 of 46
ICEpower ASP-Series Designers Manual, Professional Analog Amplifier w/ ICEpower Supply Version 1.4 Setup 6: 1000ASP with 1000A hanger AP channel Amplifier Switching frequency AP output Load Ch1 1000ASP 352 kHz AP1 bal GND 4 Ohm Ch2 1000A 330 kHz AP2 bal GND 4 Ohm Please note! Even though the 1000A module has limited bandwidth, ICEpower strongly recommends using the 1000ASP to power the bass driver with the hardest load. This is because the integrated protection features only protects the ASP-module itself and not the hanger modules.
