Meanings of the abbreviations on the SMPS power supplies

QR, R : SINGLE or DUAL power supplies with classical LLC resonance filter for Class AB or D amplifiers. SMPS R are characterized by their very good price/quality ratio.

RE : SMPS power supplies with differential outputs and multiple resonance filter voltages, including an LLC filter with low noise EMI filter (with CLC filter at low ripple output). Suitable for high-end amplifiers in Class AB, D or T. Replaces conventional linear power supplies advantageously. (Generally suitable for TA2022, TDA8920, TDA8950, IRS2092 amplifiers).

RS : SMPS power supplies close to RE but with Single Rail Output resonant filter including LLC filter with low noise EMI filter (with CLC filter at low ripple output). Suitable for high-end amplifiers in Class AB, D or T. Replaces conventional linear power supplies advantageously.

RXE : The high-end SMPS 600W, 800W and 2000W featuring the latest generation LLC resonant filters (with CLC filter at low ripple output) with high-end FET transistors. Specially recommended for high-end Class D amplifiers (IRS2092, Hypex, CXD). Can also be used with Class AB amplifiers.
