Product Details

Hypex SMPS3kA400 2 x 65 VDC 3000 Watt Switch Mode Power Supply


Key features are high efficiency over the entire load range, extremely small form factor, low weight and very low radiated and conducted EMI. The SMPS also features an advanced over current protection which in case of temporary overload limits the output current, only when the overload condition remains for a longer time the supply will enter hiccup mode until the overload condition disappears. This feature combined with large primary electrolytic buffer capacitors leads to the capability of delivering high dynamic headroom power to the connected amplifier.


The SMPS also includes an auxiliary isolated supply and a control circuit directly interfacing with the UcD amplifier modules. The supply is triggered for normal operation or latched off in case of critical fault via in built-in actuators. The SMPS is optimized from the first phase of design to final implementation to realize the lowest possible EMI signature required of the most demanding audio applications.


To connect multiple NC400 amplifier modules the additional SMPS1200A400 onto 2 x NC400 Connection kit is required. For every two NC400 modules there's one SMPS1200A400 onto 2x NC400 Connection kit requierd.
