Elektor ±40 V Linear Voltage Regulator Kit

Description

An alternative power supply for the Elektor Fortissimo-100 Power Amplifier

For those who object to a switch-mode power supply for the Fortissimo-100 Power Amplifier, this kit yields a linear, symmetrical, voltage regulator marked by low dropout voltage, high output current, and excellent stability – all obtained from discrete components.

Bearing in mind that nearly all high-performance audio power amplifiers benefit from a stabilized power supply, this linear power supply is specifically designed for a symmetrical output voltage of ±40 V and peak currents of 13 A (15 A peak achievable). As an example, the average current drawn by a Fortissmo-100 amp driving a 3 Ω load is 4 A per regulator.

Specifications

Input voltage range 52 V DC (low power usage) to 43 V DC
Output voltage range approx. 38.9 V DC to 41.4 V DC (theoretically)
38.6 V DC to 41.1 V DC (measured)
Dropout voltage at 6 A 42 V
Dropout voltage at 9.5 A 43 V
Dropout voltage at 13.5 A 44 V
Max. current 15 A peak (half sinewave), 4.8 A (average)
SOAR protection 15 A at 45 V DC in
Ripple rejection >60 dB (@ 5 A DC load)
No-load input current 27 mA (@ 52 V DC input)
