Bipolar power supply for Class D amplifier 900W. S

Description: Line power supply L_SMPS 900W L_SMPS900 is a switching unstabilized power supply with bipolar output voltage. * low switching noise; * high output power; * bidirectional synchronous rectifier suppressing pumping effect; * increased capacitance of high-voltage capacitors; * extended control options; The L_SMPS600 is a high efficiency, safety class 2 switching power supply specifically designed for use with UcD/NCore/Purifi amplifier modules. Key features include high efficiency over the entire load range, small form factor, low mass and very low radiated and induced EMI. The L_SMPS600 features overcurrent protection with a high turn-on threshold, combined with large primary electrolytic buffer capacitors for high performance and guarantees high dynamic power at the output of the connected amplifier. Over the entire power range, the output transistors operate in switching mode at zero voltage and near zero current. The current through the transformer is close to sinusoidal, with a minimum of high-frequency harmonics, thus reducing radiated noise and increasing efficiency. The lack of stabilization and very low characteristic impedance of the converter improves the dynamic performance . TThe L_SMPS600 is equipped with an auxiliary +/-15V bipolar source and load control circuitry that interfaces directly with our S_AUDIO line of amplifiers and is also compatible with UcD/NCore/Purifi modules. The STBY signal is generated for the load under conditions of line voltage presence, no overcurrent, no overtemperature, and after the end of soft start. In addition, it is possible to quickly shut down the power supply unit with an additional signal in case of external alarms. Optionally, the unit can be equipped with a timer-based audio auto-activation scheme, as well as an additional independent source of standby voltage 5V 100mA.
