For sale, eight brand new ICEpower 300A2 amplifier modules, $85/ea + actual shipping cost. I purchased a 20 ct carton of these modules directly from ICEpower in April 2022. I am keeping 12 modules for various projects and am selling the remainder to help recoop the cost of buying more modules than I needed to get better bulk pricing. For reference if you buy a single module directly from ICEpower it will be $171.
Cable kits are currently unavailable from ICEpower and the vast majority of the spec'd JST housing / contacts are not available for purchase from typical suppliers (Digikey, Mouser, Newark, etc). As a result I have found alternative housings from TE that fit the receptacles on the module. I will include the following with each module so that you can make your cabling unless you request otherwise.
P1: TE 1744036-3 housing, TE 1123721-2 contacts (x3)
P3: TE 440129-6 housing, TE 1735801-1 contacts (x6)
P4: TE 1-1123722-2 housing, TE 1123721-2 contacts (x2)
P5: TE 1-1123722-2 housing, TE 1123721-2 contacts (x2)
P6: JST PHDR-08VS housing, JST SPHD-001T-P0.5 contacts (x6)
P7: TE 1-1470107-6 housing, TE 1470106-1 contacts (x10)
These modules are based on ICEpower's newest ICEedge IC and deliver vastly improved performance over past ICEpower offerings. I am personally using these modules as they have good power output, low noise, decent THD+N performance, low output impedance, high input impedance, balanced inputs, reasonable gain and good thermal design (integrated heatsink tapped for M3 which can be attached to a larger external heat sink like that of a Modushop dissipante case).
Basic specs below from datasheet.
output power @ 1% THD+N, 20 Hz to 20 kHz, 2 ch driven: 280 W x 2 in to 4 ohm, 145 W x 2 in to 8 ohm, 560 W x 1 in to 8 ohm
residual noise, 20 Hz to 20 kHz, unweighted: 30 uV (SE), 45 uV (BTL)
gain: 25.7 dB (SE), 31.7 dB (BTL)
input impedance, 1 kHz: 38 kOhm
1 kHz SINAD at 5 W in to 4 ohm: 100 dB
output impedance, 20 Hz to 20 kHz: < 40 mOhm (SE), < 65 mOhm (BTL)
These modules require a separate power supply. ICEpower offers their 1500S power supply which is a great match for multiple module builds but is overkill for smaller builds and has not been in stock for some time. Micro Audio offers alternative power supplies that work very well with these modules. I am personally using a single Micro Audio SMPS1K-PFRC2 power supply (+/- 55 V, +15 V driver, +/- 12 V aux) to supply two modules in my builds. This supply works great and the end result has very well behaved turn on / off behavior with no nasty pops, a built in 12 V trigger and is able to achieve the datasheet power figures. I am using an extra capacitor PCB with my SMPS1K-PFRC2, they also offer a supply called the Cobra S2 which has dual outputs and added capacitance to achieve the same result. For single module builds there is also the SMPS630-G which is lower power / smaller.
Buyer pays actually shipping cost, if you are interested in purchasing a module send me a PM with your zip code and how many you would like and I will send you a quote.
