Predator XE PSU
The Predator XE PSU is a complete supply solution especially developed for class D amplifier modules. With an appropriate transformer it will generate both a traditional +/- 60V main supply and a linear, regulated +/-12V supply. The rectification for the main supply employs dual rectifier bridges to avoid charging currents to flow in the ground plane. A pair of high-quality electrolytic capacitors rated at 15.000uF/80V provides low ripple and provides an excellent power reservoir for bass and transient handling.
The Predator XE supply needs a transformer rated at 2*42VAC for the main supply (typically 100-500VA) and 1*15VAC or 2*15VAC (better) for the regulated supply. For low-profile enclosure (i.e. 1-unit 19" rack enclosures) we recommend one or two of our toroidal "pancake" transformers. For smaller amplifiers a single transformer can be used - but typically two are employed (with +/- windings on each transformer paralleled).
The supply is delivered with solder terminals for direct connection of supply wires. Alternatively one or two 4-pole terminals can be mounted (sold separately).
